Signalling deviation for DTMF and high-speed Trunking data should
be checked whenever the radio is serviced and must be adjusted when
any of the modulation circuitry is replaced. Before adjusting signalling
deviation, radio compensation/deviation adjustments must be made.
No adjustments are required for DPL, PL, or Trunking connect time
deviation.
