5. ALIGNMENT (LEVEL 3 SERVICE ONLY)
This procedure is applicable to all versions of
SRP9100
portable transceivers.
p
If the radio contains customer configuration data that must be retained, you
must
first
use the SRM/SRP
Personality Programmer (FPP) software to read all radio configuration files and save them on to alternative
media
before
commencing the alignment procedure.
When the Alignment is completed, use the FPP software to retrieve this stored data and write it back to the
radio.
It is preferred that the radio remain installed in its cast and ABS case so that appropriate shielding and
battery supply are maintained.
Note. Final Tx power adjustments must be performed with the radio board installed in the chassis.

Caution
Preparing the radio for alignment will erase from the radio all customer PMR and Trunking
configuration data (channel, signalling information etc). The only data retained by the Alignment
Tool is the factory alignment data for the radio (DAC settings for Tx power, front-end tuning etc).
Using the Alignment Tool will allow changes to the original factory alignment and will invalidate
all warranties and guarantees unless performed by an authorised level 3 service centre.
