CAUTIONS FOR OPERATING TEMPERATURE
1. The camera cannot operate properly at temperatures lower than -50ºC.
2. Even if the surrounding temperature is -50ºC or higher, the camera may not thaw itself and
operate properly depending on the installation environment.
3. Always keep the power on, so the camera can maintain its internal temperature at -10ºC or higher.
4. If the camera was turned on after being left at temperatures lower than -50ºC for a long duration:
- If the internal temperature is lower than -20ºC, the camera does not transmit video signals
and displays a black screen along with the "Wait to warm up(xx Left)" message, instead of
operating properly.
- If the internal temperature is higher than -20ºC and lower than -10ºC, the "Wait to warm up(xx
Left)" message disappears as the camera resets itself and enters the operation mode.
However, only manual P/T operation is in effect while the Sequence and Turbo commands are
limited in use.
- If the internal temperature is higher than -10ºC, the camera activates all Sequence and Turbo
commands.
