Simoco SRM9000 Alignment Manual

ALIGNMENT (LEVEL 3 SERVICE ONLY)
This procedure is applicable to all versions of SRM9000 mobile transceivers.
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.
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 aluminium extruded case throughout this alignment
procedure. If the radio is to be aligned when removed from the case, a temporary heat sink must be fitted
under the Transmitter PA module and the receiver output must be kept below 100mW.
Note. Final Tx power adjustments must be performed with the radio board installed in the chassis.
