OPTIONS
If the Audio Test is ENABLED, it is performed next on the Radio. The field status
changes to RUNNING and the screen prompts to, “Install Audio Connectors.
Press CONT when ready”. It is extremely important that audio connections to the
Radio are installed correctly. Press F4 CONT to continue the test.
The COM-120C establishes a Group Call identical to the Group Call used in the
Radio Test.
If the PTT cable is properly connected, the Radio is instructed to automatically
engage the PTT button. Otherwise, manually depress the PTT button.
Once the Radio is connected via Group Call, the screen displays the message:
“Taking Measurements...”. The PTT button must remain depressed (if manually
doing PTT) during measurements or the Audio Test terminates. The field status
indicates DROPPED. The message, “CALL DROP” is briefly displayed.
After the Transmitter Audio Tests are complete, the COM-120C prompts to release
PTT (if manual PTT) and calls the Radio to do Receiver Audio Tests. When the
call to the Radio is complete, the screen prompts to, “Set Radio Volume to
Maximum. Press CONT when ready”. Check the Radio for a busy (‘BSY’) light
indicator and/or a Group Call (GR) light indicator with the caller’s Logical ID
which indicates a successful call to the Radio. If the call is not successful,
ABORT the test.
If the F4 CONT is pressed, the screen displays the message: “Taking
Measurements”. The field status changes to COMPLETE when the test is finished
and goes to the next ENABLED part in the Automatic Test.
C. REPEATER TEST
If ENABLED, Repeater Test executes next. The field status changes from
ENABLED to RUNNING. The Working Channel programmed from the Setup
screen is used for the RF Frequencies. The Repeater Test is a conventional-
mode test.
Manually control the Repeater Transmitter/Receiver as instructed by the COM-
120C. When the test begins, the screen prompts, “Turn on Repeater transmitter
now”. The screen displays the message: “Taking Measurements..” when the
transmitter is on,.
The Repeater Transmitter must remain on during measurements. If not, the test
terminates and the field status indicates DROPPED. The message, “REPEATER
DROP” is briefly displayed.
If the Audio Test is ENABLED, it is performed next on the Repeater. The field
status changes to RUNNING and the screen prompts to, “Install Audio
Connectors. Press CONT when ready”.
It is extremely important that audio connections to the Repeater are installed
correctly.
Press F4 CONT to continue the test. If the Repeater’s Transmitter is not on, the
screen prompts for it to be turned on. Once the Repeater is transmitting, the
screen displays the message: “Taking Measurements...”.
The Repeater Transmitter must remain on during measurements. If not, the test
terminates and the field status indicates DROPPED. The message, “REPEATER
DROP” is briefly displayed. The field status changes to COMPLETE after the test.
