L1 Tx Power Adjustment (L1 POWER)
Transmit, and adjust the output power level for 50 mW
m
(+50/-30 mW) by rotating the DIAL, then press the V/M
button. Rotate the DIAL to select the next setting.
TX Deviation Adjustment (MAX DEV)
Inject a 1 kHz audio tone at a level of 50 mV (rms) to
m
the MIC jack. Press the V/M button, then transmit and
adjust the deviation for 4.5 kHz (±0.2 kHz) (USA Ver-
sion: 4.2 kHz (±0.2 kHz)) by rotating the DIAL, then
press the V/M button. Rotate the DIAL to select the next
setting.
CTCSS Tx Deviation Adjustment (TN 67.0)
Press the V/M button, then transmit and adjust the de-
m
viation for 0.5 kHz (+0.05/-0.1 kHz) by rotating the
DIAL, then press the V/M button. Rotate the DIAL to
select the next setting.
CTCSS Tx Deviation Adjustment (TN 183.5)
Press the V/M button, then transmit and adjust the de-
m
viation for 0.5 kHz (±0.1 kHz) by rotating the DIAL,
then press the V/M button. Rotate the DIAL to select
the next setting.
CTCSS Tx Deviation Adjustment (TN 254.1)
Press the V/M button, then transmit and adjust the de-
m
viation for 0.5 kHz (±0.1 kHz) by rotating the DIAL,
then press the V/M button. Rotate the DIAL to select
the next setting.
DCS Tx Deviation Adjustment (DCS DEV)
Press the V/M button, then transmit and adjust the de-
m
viation for 0.6 kHz (±0.1 kHz) by rotating the DIAL,
then press the V/M button. Rotate the DIAL to select
the next setting.
Press the MON/F to activate the TX Power and Devia-
tion alignment routine.

m
(±0.1 W) by rotating the DIAL, then press the V/M but-
ton. Rotate the DIAL to select the next setting.
High TX Power Adjustment (L1 POWER)
Transmit, and adjust the output power level for 50 mW
m
(+50/-30 mW) by rotating the DIAL, then press the V/M
button. Rotate the DIAL to select the next setting.
TX Deviation Adjustment (MAX DEV)
Inject a 1 kHz audio tone at a level of 50mV (rms) to the
m
MIC jack. Press the V/M button, then transmit and ad-
just the deviation for 4.5 kHz (±0.2 kHz) (USA Version:
