Refer to your radio service manual for the MDC signalling deviation alignment procedure. This procedure should only be attempted by qualified service personnel.
MDC 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 MDC deviation.
MDC 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.
PROGRAMMING PROCEDURE:
1.Press F2 at the MAIN MENU. The SERVICE MENU appears.
2.Press F4. The SIGNALLING ALIGNMENT MENU appears.
