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.
The function key descriptions and field definition are on the following page.
PROGRAMMING PROCEDURE:
1. Press F2 at the MAIN MENU. The SERVICE MENU appears.
2. Press F4. The SIGNALLING ALIGNMENT MENU appears.
3. Press F4. The TRANSMIT SIGNALLING: MDC 1200 screen appears.
4. Press Tab to select the desired field, or press the desired function key (F1 - F10).
5. If a field is selected, press the up/down arrow keys to select choice or value.
