(PLL REF)

 Transmit and adjust the counter frequency for within ±300Hz by rotating the
DIAL, then press the [

V/M]

 button. Rotate the DIAL to select the next setting.

   

430MHz band Alignment

  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)
