Repeat Steps 2 thru 5 at 12.5 kHz channel spacing.
7.
Select radio channel 1 at 25 kHz channel spacing.
8.
Adjust Squelch _Offset_Low value until squelch
opens at 8 dB SINAD. Adjustment range should be
very small. When value is increased at 0.02 steps
(values will be 0.02, 0.06, etc.), squelch open level
goes down. When value is decreased at 0.02 steps
(values will be 4.98, 4.94, etc.), squelch open level
goes high.
9.
Select radio channel 1 at 12.5 kHz channel spacing.
10.
Adjust Squelch_Offset_Low value the same as Step 8.
11.
Select radio channel 3 at 25 kHz channel spacing.
12.
Adjust Squelch_Offset_High value the same as Step
8.
13.
Select radio channel 3 at 12.5 kHz channel spacing.
14.
Adjust Squelch_Offset_High value the same as Step
8.
TCXO
1.
Connect Communications Monitor to radio.
2.
Key the radio and monitor the transmitter frequency
stability.
3.
Adjust TCXO reference voltage using the PC Pro-
gramming Software to get required transmitter fre-
quency (typical voltage should be 2.20V, adjustable
range is between 2.00 and 2.40 V).
BATTERY INFORMATION
CHARGE BEFORE USING
Insert the radio into the slot on the charger and ensure that
the ON/OFF/VOLUME control is in the OFF position. Con-
nect charger to a 120 VAC outlet. Charge the battery for the
