Check the following guide for the possible cause of a problem before contacting service.
Symptoms 
Solutions
The system power does not turn 
on.
Check the power cable is connected correctly.
Check the input voltage is correct.
Check the main power switch is turned on.
If the system power does not turn on even if the power cable is connected correctly, 
please contact the service center.
The system power is turned on 
but no video data is displayed 
on the monitor.
Check the input mode of the system. Make sure the mode is set to VCS.
Unplug the power cable and plug in again.
The subject is not clear enough 
to see.
Adjust the camera brightness and white balance in User Preferences : Diagnostics 
setting menu. 
The remote control is not 
working.
Check the battery.
Make sure that the battery polarities are connected with (+) and (-) matched correctly.
Check the remote control contains three AAA batteries that are in good working 
condition.
Verify whether objects are obstructing the sensor on the front of the camera.
Check that the LED on front of the camera flashes bright blue when you use the remote 
control.
The image is not visible.
Verify that the blue LED on the front of the camera is lit, indicating that power is active, 
and reboot the system if necessary to verify that the camera turns on.
The sound is not audible
If you are unable to hear the ringer when an incoming call arrives, adjust the Ring Tone 
Volume preference in User Preferences : Audio. Muffled audio reception from the far 
side may be caused by highly reverberant rooms. If you are experiencing poor audio 
reception, add more sound absorbency to the room and speak in close proximity to the 
microphone. 
Degradation in audio quality can also be caused by faulty microphones or dust and debris 
on the microphones. Do not use any kind of liquid or aerosol cleaner on the camera that 
includes microphones. A soft, slightly damp cloth is sufficient to clean the top surface of 
the units if necessary.
Ensure both ends are not muted. Verify that the audio out cables are properly connected 
to the monitor and that any external speaker systems are powered and configured 
correctly.
