❒ Modulation Limit: Reference Attenuator
In addition, signalling deviation for DTMF, MDC, Single Tone,
SECURE and High-Speed Trunking Data should be checked every time
the radio is serviced. Prior to adjusting signalling deviation, radio
compensation/deviation adjustments must be made. No adjustments
are required for DPL, PL or Trunking Connect Tone Deviation.
