HELP
Transmit Power Alignment is required after replacing (or servicing) the RF
Board. This alignment limits the RF power from the radio and must be
performed at multiple frequencies to allow for proper alignment
across the entire RF band. The RF band is divided into frequency
zones with a calibration point (value) in each zone.
This procedure should be attempted only by qualified
!
service personnel. Failure to perform alignment
procedures properly may result in seriously degraded

radio or system performance.
Refer to your Radio Service Manual for the Transmitter Power
Alignment procedure.
1. Press F6 at the TRANSMIT POWER screen to key up the radio. (The
radio's RF output must be terminated into a 50 ohm load.)
2. While transmitting, modify the Tx power softpot setting using the
UP/DOWN arrow keys. To increase the adjustment speed, use the
Shift-UP/DOWN arrow keys.
3. A relative Tx power value will be displayed, but you must
determine the actual transmitter power output from the service
monitor.
4. Press F6 to de-key the radio and Tab to move between frequency
points.
5. Press F8 to save the new value.
Use UP/DOWN Arrows To Adjust Softpot.
