Verifying the Transmitter
Prerequisites: Take the MTS out of service.
WARNING: RF energy burn hazard. Disconnect power in the cabinet to prevent injury and
equipment damage while disconnecting and connecting antennas.
IMPORTANT: Unless it is already out of service, Motorola Solutions recommends performing
this procedure during off-peak hours to minimize or eliminate a disruption of service to system
users.
When and where to use: This procedure provides commands and responses to verify proper
operation of the transmit path for the Power Amplifier and is recommended after replacing the Base
Radio module.
IMPORTANT: BR-Arch-1 Base Radios: To avoid the risk of causing a high bit error rate to
occur, do not use 385.572 MHz and 419.175 MHz as receiving frequencies in the Base Radios
of the MTS.
Procedure:
1 Log on to the Test Application of the Base Radio.
See Logging on to the Test Application on page 242.
2 Type power -otxch1 -a0 in the command line.
This command dekeys the transmitter.
