Reference Oscillator Alignment

Adjustment of the reference oscillator is critical for proper radio operation. Improper adjustment will

result not only in poor operation, but also in a misaligned radio that will interfere with other users

operating on adjacent channels. For this reason, the reference oscillator should be checked every

time the radio is serviced, or once a year, whichever comes first. The frequency counter used for this

procedure must have a stability of 0.1 ppm (or better).

NOTE: Reference oscillator alignment is required after replacing (or servicing) the transceiver board.
