HELP
Refer to your radio service manual for the DTMF signalling deviation alignment procedure. This procedure should
only be attempted by qualified service personnel.
DTMF deviation should be checked any time the radio is serviced and must be adjusted whenever any of the
modulation circuitry has been replaced. All radio compensation/deviation adjustments must be made before
adjusting DTMF deviation.
DTMF deviation is increased or decreased by first keying the radio via F6, and then by pressing the up/down
arrow keys respectively. A relative deviation value is displayed, but the actual transmitter deviation must be
determined from your service monitor. Set your modulation analyzer to read peak deviation.
