Refer to your radio service manual for the transmit deviation limit alignment procedure. This procedure should
only be attempted by qualified service personnel.
Transmit deviation limit alignment is a way of correcting for deviation sensitivity versus RF frequency variations in
the VCO. The transmit and receive bands are divided into frequency zones with a calibration point (value) in each
zone. Compensation for each of these points must be checked and adjusted if the VCO is replaced.

2. Press F2. The TRANSMITTER ALIGNMENT MENU appears.
3. Press F5. The TRANSMIT DEVIATION LIMIT screen appears.
4. Press Tab to select the desired field, or press the desired function key (F1 - F10).
