L If the power of the Gazer recorder is turned on, the car’s radio will not work properly. In some cars, there is interference with the radio with the DVR on. Interference may also be related to the operation of the power supply of the Gazer DVR, which uses a pulse voltage conversion circuit. To avoid interference, please do not install the DVR’s power cord near the radio antenna. Do not place the main power supply of the DVR in close proximity to the radio or its antenna connector. You can easily use cigarette lighter socket extensions to remove the cigarette lighter socket and the DVR power supply from the car radio.
