What is not working? — technical support Safe initial checks and information to help support investigate. CCTV camera: no picture Czytaj po polsku Black screen, an offline camera or no picture on your phone. These are initial checks, not a diagnosis or repair instructions. Follow the exact equipment manual and site safety procedures. Safe initial checks Establish the scope: one camera or all cameras? Is the picture available on the recorder's local monitor but missing from the app? Note when the fault began. Check that the monitor is switched on and the correct input is selected. Record the exact app message. Do not share passwords or device-sharing codes. If you have authorised access, read the channel status on the recorder: offline, authentication failure or another message. A black screen alone does not prove that the camera has failed. What not to do Do not factory-reset equipment, open power supplies or move cables at random. Do not expose the camera to the Internet as a workaround. What to tell support Provide the camera number, recorder model, exact message and whether local viewing works. Redact bystanders and credentials from screenshots.

Model-specific source material does not replace your own equipment manual. CCTV footage keeps freezing Czytaj po polsku Delayed live view, jerky movement or frozen frames. These are initial checks, not a diagnosis or repair instructions. Follow the exact equipment manual and site safety procedures. Safe initial checks Compare the affected camera with other cameras, and the local monitor with your phone. Note whether live viewing, recorded playback or both are affected. If the app offers a viewing-quality option, try a lower-quality preview in the app only. Do not change recording quality. View one channel rather than several at once. Compare your trusted Wi-Fi connection with mobile data. Better playback on one connection helps narrow the investigation but does not identify a failed component on its own. What not to do Do not format storage or switch off recording. Avoid repeated restarts during an incident whose footage may be needed. What to tell support Report the interruption times, channel number, connection type and the results of comparing local viewing with the app. Contact DATPOL support · 55 621 29 29 Source material BCS Ultra — diagnostyka podglądu / viewing troubleshooting DATPOL guidance, 15 September 2026. Model-specific source material does not replace your own equipment manual. CCTV recorder: missing recordings Czytaj po polsku Live view works, but recordings cannot be found. These are initial checks, not a diagnosis or repair instructions. Follow the exact equipment manual and site safety procedures. Safe initial checks Select the correct channel, date and time range in playback. Check the time displayed by the recorder, but do not change it now. An authorised user can inspect storage status and the recording schedule. Note messages such as no disk, disk error or no recording. Checking status does not require initialising storage. Record whether all footage, one channel or a particular time period is missing. Some installations record events rather than continuously; confirm the intended setup with the administrator. What not to do Do not format, initialise or attempt to repair storage without agreeing this with support. Say immediately if footage may be evidence of an incident. What to tell support Provide the required time period, channel, storage status and the last known successful recording.

These are initial checks, not a diagnosis or repair instructions. Follow the exact equipment manual and site safety procedures. Safe initial checks If there is no burning smell, leak or damage, check the selected mode, temperature setting and timer. Note any error code. Replace remote-control batteries only as described in the manual. Visually check that the air inlet and outlet are not obstructed. Do not remove service covers or touch internal parts. Check whether a central controller intentionally restricts operation. Start-up delays vary by model; consult the manual rather than repeatedly switching the power off and on. What not to do A burning smell, hot cable, repeated protective-device trips or a leak requires stopping operation and contacting support. Isolate power only from a safe, dry location if you know how to do so. What to tell support Provide the model, operating mode, temperature setting, error code and when cooling stopped.

These are initial checks, not a diagnosis or repair instructions. Follow the exact equipment manual and site safety procedures. Safe initial checks Assess safety from a dry location first. If water reaches a socket, cable or electrical installation, do not touch the appliance or plug and do not step into the water. Stop using the equipment. Isolate its supply only by a safe, accessible method; if that is not possible, keep people away and obtain professional help. If the surroundings are safe, note where the water appears, when the leak started and the temperature shown by the equipment. Do not assume it is harmless condensation. What not to do Do not use wire to clear a drain, chip away ice or open the casing. Do not dry electrical equipment with a hairdryer. For immediate danger or fire in Poland, call 112. What to tell support Provide the model, leak location, temperature and a photograph taken from a safe distance.

Model-specific source material does not replace your own equipment manual. A socket has no power Czytaj po polsku One socket or part of the building has lost power. These are initial checks, not a diagnosis or repair instructions. Follow the exact equipment manual and site safety procedures. Safe initial checks First look for scorching, melting, moisture or damage. If any is present, do not test the socket: stop using it and call an electrician. Without dismantling anything, establish whether one appliance, one room or the whole site has lost power. Ask the site manager about planned interruptions. Note what happened immediately before the fault: a storm, an appliance being connected or a leak. A loss of power does not mean that internal conductors are safe to touch. What not to do Do not unscrew the socket or insert tools. Do not increase a protective device's rating or repeatedly reset it after it trips. What to tell support Provide the location, extent of the power loss and visible symptoms. If there is smoke, fire or danger to people, move away and call 112 in Poland.

Model-specific source material does not replace your own equipment manual. Scorched socket or burning smell after a storm Czytaj po polsku Urgent: do not use the damaged installation. These are initial checks, not a diagnosis or repair instructions. Follow the exact equipment manual and site safety procedures. Safe initial checks Do not use the socket or connected equipment. Do not touch a melted plug, scorched parts or wet surroundings. Keep other people away. If there is smoke, fire, sparking or immediate danger, leave the affected area, follow the evacuation procedure and call 112 in Poland. Never use water on energised electrical equipment. Consider isolating the supply only if access and the distribution board are dry and safe, and you know how to operate it. Do not put yourself at risk to switch off power. An electrician must assess the installation before reuse. What not to do Do not re-energise the affected circuit. Cooling down or the smell fading does not establish that it is safe. A photograph alone cannot establish the cause. What to tell support Once people are safe, report the location, storm time and observed symptoms. An online support ticket is not a substitute for contacting emergency services.

Choose a symptom on the homepage or use search. Use PL / EN for Polish or British English. Paired articles link directly to their translation. Guidance is written for sites in Poland and does not replace an equipment manual or an on-site assessment. If there is smoke, fire or immediate danger, move away and call 112 in Poland. An online ticket is not an emergency call. If the guidance does not resolve your issue, contact support. Provide the location, symptoms and error message, but never passwords or alarm codes. Circuit breaker trips when an appliance starts Czytaj po polsku A circuit trips when a kettle, heater or machine is switched on. Guidance for people using properties in Poland, written in British English. These are safe initial actions, not a diagnosis or electrical repair instructions. Smoke, fire, electric shock or immediate danger: move away and call 112 in Poland. Do not touch anyone who is still in contact with an electrical supply. A DATPOL ticket does not replace an emergency call. What to do now Stop using the appliance associated with the trip. Do not restart it merely to reproduce the fault. Note which equipment was running and which rooms lost power. Photograph circuit labels only from a safe position, without removing covers. You may unplug a portable appliance only if its plug and socket are dry, undamaged, cool and readily accessible. Do not touch scorched or sparking parts. Repeated tripping requires an electrician. The position of a breaker alone does not establish whether the cause is an overload, faulty equipment or a wiring fault. What not to do Do not fit a higher-rated protective device, hold a breaker on or bypass protection. Do not test suspect equipment on another circuit. Do not open the distribution board or take live measurements. What to include in your support request Provide the appliance name and rated power from its documentation, the time, other equipment in use, circuit label and whether the trip was immediate or delayed. Do not cause another trip to obtain this information.

Do not touch anyone who is still in contact with an electrical supply. A DATPOL ticket does not replace an emergency call. What to do now Treat the trip as a reason to check safety, not to remove protection. An RCD detects a current imbalance; the symptom alone does not locate a fault. Record whether rain, flooding, building work or an appliance starting coincided with the trip. Do not touch wet accessories. Read or photograph markings only if visible without removing covers. A TEST/T button can help identify a device, but one device may combine several protective functions. If trips recur, leave the affected circuit off and arrange an electrician. Tell support about critical loads, such as refrigeration or medical equipment, so assistance can be planned safely. What not to do Never bypass an RCD or protective conductors. Do not reset repeatedly or touch equipment casings to look for a fault. The test button does not replace installation testing; follow the manufacturer's test procedure and interval. What to include in your support request List affected circuits, protective-device markings, timing, weather conditions and recent work. Do not open a distribution board to take photographs for support.

A DATPOL ticket does not replace an emergency call. What to do now Establish the extent from existing observations: the whole building, one floor or one circuit. You can ask neighbours, but their answer is not a definitive diagnosis. Check the relevant network operator's notices on your phone. In the Energa-Operator area, a map lists faults and planned outages; information is also available on 991. Observe accessible protective-device positions and labels without removing covers. Do not interfere with the meter, seals or service fuses. Report a network problem to the operator and an internal installation fault to the property manager or electrician. If the boundary is unclear, describe the symptoms and ask which service should investigate. What not to do Never feed a generator into a building socket. Backup power must use a purpose-designed connection arrangement. Darkness does not mean that every conductor is dead. What to include in your support request Provide the address, start time, extent, any operator notice, critical equipment and an on-site contact number.

Smoke, fire, electric shock or immediate danger: move away and call 112 in Poland. Do not touch anyone who is still in contact with an electrical supply. A DATPOL ticket does not replace an emergency call. What to do now Note whether one fitting or several rooms are affected and whether it started suddenly. Do not reproduce the symptom by switching on further heavy loads. If several lights suddenly change brightness markedly, or other appliances misbehave at the same time, stop using the affected equipment and urgently contact an electrician or property manager. Do not assume it is simply a faulty lamp. For a single fitting, find the model in existing instructions or packaging and note whether a dimmer is fitted. Support can investigate component compatibility and the circuit condition. Crackling, a burning smell, smoke or signs of overheating make this urgent. Do not touch the damaged fitting. Move away and call 112 in Poland if there is immediate danger. What not to do Do not tighten wiring or fittings or take measurements at a socket. Do not climb a ladder in poor lighting just to read a label. Recording a video is never more important than staying safe. What to include in your support request List the rooms and fittings, any dimmer, the time and recent lighting changes.
