Transmit Deviation
Balance
(Compensation)
AlignmentFrom the MAIN MENU, press F2 twice and then F4 to access this
screen.
Refer to your Radio Service Manual for the Transmit Deviation Balance
Alignment (Compensation) procedure.
This alignment procedure balances the modulation contributions of
the low and high frequency portions of a baseband signal. Power
alignment is critical to the operation of signalling schemes that have
very low frequency components (i.e., DPL) and could result in
distorted wave-forms if improperly adjusted.
This procedure 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.
Balanced attenuator alignment balances the modulation sensitivity of
the VCO and reference modulation (synthesizer low-frequency port)
lines. It is a method 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 in each zone.
Note: Balanced attenuator alignment is required after controller
board or RF board replacement and servicing.
Using the UP/DOWN arrow keys, adjust compensations according to
instructions provided in your Radio Service Manual. Performing this
procedure automatically calculates compensation alignment.

This screen can be accessed for Portables only. Refer to your Radio Service
Manual for the Transmit Deviation Limit Alignment procedure.
Transmit deviation limit alignment is a method 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.
Note: Compensation for each of these points must be checked
and adjusted if the VCO is replaced.

Limit Alignment
(Mobiles Only)From the MAIN MENU, press F2 twice and then F6 to bring up the
TRANSMIT CURRENT LIMIT ALIGNMENT screen.
This screen can be accessed for Mobiles only. Transmit current limit
alignment is required after RF board servicing or replacement. Refer to
your Radio Service Manual for the Transmit Current Limit Alignment
procedure. This alignment procedure limits the transmitter current
drain of the radio.
Press Ta b to select the desired field, or press the desired function key
(F1 - F10). If a desired field is selected, use the UP/DOWN arrow keys
to select the desired choice or value.
Programming Procedure1. Press F6 to key up the radio. (The radio’s RF output must be
terminated into a 50 ohm load).
2. While transmitting, measure current drain on the first test
frequency.
3. Press F6 to de-key the radio and Ta b to move between frequency
points.
Repeat the steps above for each frequency.
4. Press Ta b to select the frequency which had the highest current
reading.
5. While transmitting, use the UP/DOWN arrow keys to adjust the
transmit current limit according to instructions in the Service
Manual.
