9-6 MTR2000 MOTOTRBO Digital Upgrade: Operational Verification
9.4 Operational Verification
After the station equipment has been mechanically installed and all electrical connections have been
made, replace the new MTR3000 station front bezel by inserting one of the front bezel locking clip
into corresponding latch on the station housing, and carefully pressing the bezel on the opposite side
until the second locking clip snaps into place.
9.4.1 Applying Power
Before applying power to the station, make sure all modules are securely seated in the appropriate
connectors on the backplane and that all RF cables are securely connected.
Plug in the AC line cord that supplies power to the station Power Supply, or switch on the DC-
breaker to a station with a DC power source to the Power Supply.
9.4.2 Alignment and Configuration
After the station and ancillary equipment have been mechanically installed, properly cabled, and
power applied, the equipment must be optimized before placing the station in operation. Align with
the Tuner application followed by configuration with the CPS application.
9.4.3 Optimizing Tasks
Refer to Chapter 12 : MTR3000 Programming and Tuning for optimizing tasks.
