TROUBLESHOOTING
The system does not work
■
Make sure the door camera is powered, refer to below
■
Make sure the receiver is powered, refer to below
■
Move the receiver closer to the door camera to
receive a better signal
■
If new, make sure the door camera is programmed to
the receiver – see ‘Pre-installation Setup’ on page 3.
Door camera is not powered
This is indicated when the red confi dence light on the
front does not light when the call button is pressed.
Check;
■
The batteries are all inserted in the right direction
■
The batteries are new and Alkaline type
■
If transformer powered, the transformer is connected
to the mains and powered on
■
There is no damage to the transformer connecting
cable
■
The two wires in the transformer connecting cable
are making contact to the terminals in the unit and
in the transformer.
Receiver is not powered
■
The batteries are discharged. Place the receiver on
the charging unit for a minimum of 12 hours to
fully recharge the batteries. The receiver battery
indicator will blink once a second to indicate
charging, and will stay on when the receiver is fully
charged.
The receiver only displays a black and
white picture
■
The light level at the door camera is very low
■
The light sensor under the door camera is covered, is
too close to an adjacent object, or is facing a very
black surface.
The signal is poor, or there is interference
■
The receiver is in a signal ‘dead spot’. Rotate or
move the receiver 50cm and try again. People
walking near the receiver can also temporarily affect
the reception quality.
■
Make sure that the receiver is in range of the
door camera, approximately 30 meters in a typical
building. Move the receiver closer to see if the
picture improves. If this does not improve the
picture then there is nearby interference on the
video channel. Open the door camera and change
the video channel switch from 1 to 3, for example.
■
If there is more than one video transmitter (door
camera or others), every unit must have its video
channel switch set to a different channel.
G-11
■
A microwave oven may be in use in the path
between the door camera and receiver. Move the
microwave oven or turn it off.
■
Computers and other IT equipment can radiate
signals and affect the video quality. If this is a
likely problem, move the receiver away (at least one
metre) from the units.
The receiver chimes, followed by a beep-
beep
This indicates low battery power in the door camera.
Replace the door camera batteries.
A beep-beep tone sounds for 30 seconds
This is an alert triggered by the tamper switch indicating
someone is trying to unscrew and remove the door
camera. Check outside immediately.
The tone may sound if the screws that fi x the front of
the door camera to the rear are not fully screwed in
place.
Press any button on the receiver to stop the alert tone.
The receiver switches on randomly
This is probably due to the motion sensor on the camera
picking up passers by, passing cars or moving heat
sources.
Switch the PIR sensor off, (refer to the ‘DOOR CAMERA’
section), block off the unwanted movement, or relocate
the door camera.
Chime sounds but the picture is displayed
for only a few seconds
■
The video signal has been interrupted. Press the
Scan button to recapture the video signal, move the
receiver to another position nearby.
■
If this occurs regularly, locate the receiver closer
to the door unit, or place the receiver higher up.
Generally, the receiver will receive a stronger signal
up on a shelf, and a weak signal near the fl oor.
■
The battery charge is low. Place the receiver on
the charger for at least four hours to recharge the
batteries.
