6.5.1 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). Also, checking this parameter when the
product is placed in service is especially important if the product has been in storage for a significant
period of time (6 months or more) between being shipped from the factory and commissioned for
service.
NOTE: Reference oscillator alignment is required after replacing (or servicing) the transceiver board.
