•
Remove the 1000 Hz tone from the Line
Input and the REMOTE PTT.
•
Repeat this step for every channel.
4. Repeater Gain
•
If the station is
not
a repeater, leave the
Repeater Gain pot
RG
at 1023.
•
If the station
is
a repeater, apply an "on
channel" RF signal modulated with a 1000
Hz tone at 60% of system deviation to the
receiver.
•
Adjust
RG
pot for 60% of system deviation
(Table 8).

NOTES:
1) VOL/SQ sensitivity: 1000 mV rms = 3 kHz peak deviation (System Module, Pin, B2)
2) MOD sensitivity: 1000 mV rms = 5 kHz peak deviation (System Module, Pin, C3)
3) Refer to Handset manual, LBI-38599, for instructions on page selection.
