2.4GHz Receiver Operation:

Changing Channels:

To change channels, simply depress the Toggle/Standby switch momentarily until the

LED for the desired channel pattern is lit up. Remember to change the receiver

channel as well, since it is not automatically changed when the transmitter channel is

changed. For best performance, multiple systems transmitting along the same path

should be operated using horizontal polarization on channels 1 and 3, and vertical

polarization on channels 2 and 4.

Alarm Conditions:

When the VRX2400 receives an alarm condition from the transmitter, the active

channel LED will begin blinking.

If Alarm 1 is activated, then the active channel LED blinks once between pauses.

If Alarm 2 is activated, then the active channel LED blinks twice between pauses.

If both alarms have been activated, then the active channel LED blinks three times

between pauses.

The active channel LED will stop blinking when the alarm condition is cleared.

RSSI Mode:

To ease alignment of the receiver antenna, the received signal strength may be

viewed by placing the unit in RSSI mode. The LEDs will then act as a bar-graph

indicator, with more LEDs lit for a stronger signal.

To enter RSSI mode, hold down the Toggle/RSSI button for 2 seconds. To exit,

depress the button momentarily. The number of LEDs lit is a relative indication of

signal strength to be used only to find the best antenna position. Viewing the

received picture quality should be used in conjuction with this mode.
