5. System Programming
5.1 Audio jumper
The audio jumper has to be put on AF position in the indoor phone if there is only one indoor phone in the
system. In case there are more indoor phones in one system, only the last indoor phone is required to do that.
Meanwhile all the other indoor phones' jumpers have to be put on NC position.
Please take the following figure as reference
5.2 Video resistor
In case the image display is rolling or with any other abnormal problem and the image adjuster can not help,
please try to use the enclosed video resistors to connect between GND (G) and Video (V) terminals in the last color
indoor phone. Please take the following figure as reference.
