○
Squelch Hysteresis Adjust
(HIS)
Rotate the DIAL for minimum squelch hysteresis, then press the [V/M] button.
Rotate the DIAL to select the next setting.
○
Squelch Preset Threshold
(tHL)
Inject a -15dBµ RF signal (1 kHz tone @ ±3.5kHz deviation), then press the [V/M]
button. Rotate the DIAL to select the next setting.
○
Squelch Preset Tight
(tIg)
Adjust the generator level for a -4dBµ signal, then press the [V/M] button. Rotate
the DIAL to select the next setting.
○
Low-Scale S-1 Adjustment
(S1)
Adjust the generator level to -7dBµ (1 kHz tone @ ±3.5kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○
S-Meter Full-Scale Adjust
(S9)
Adjust the generator level to +20dBµ (1 kHz tone @ ±3.5kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○
Wide Low-Scale S-1 Adjustment
(S1)
Adjust the generator level to 0dBµ (1 kHz tone @ ±20kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○
Wide S-Meter Full-Scale Adjust
(S9)
Adjust the generator level to +20dBµ (1 kHz tone @ ±20kHz deviation), then press
the [V/M] button. Rotate the DIAL to select the next setting.
○
High TX Power Adjust
(HPo)
Transmit and adjust the output power level for 3W ±0.3W by rotating DIAL, then
press the [V/M] button. Rotate the DIAL to select the next setting.
○
Low TX Power Adjust
(LPo)
Transmit and adjust the output power level for 50mW ±30mW by rotating DIAL,
then press the [V/M] button. Rotate the DIAL to select the next setting.
○
TX Deviation Adjustment
(dEV)
Transmit and adjust the deviation for 4.2KHz ±0.2KHz by rotating DIAL, then
press the [V/M] button. Rotate the DIAL to select the next setting.
This completes the UHF band internal alignment routine, to save all settings and
exit, press [BAND] button.
