Transmitter Status
This screen displays the transmitter state. “Keyed” means the transmitter is set to
transmit; “dekeyed” means the transmitter is prevented from transmitting. The
transmitter can be keyed or dekeyed by selecting
Manual Key
from the
Configuration
menu (page 56). This setting is used when working on the radio,
and the radio must be keyed to evaluate transmitter output power.
Show Temperature
and Voltages
This screen displays the radio’s internal temperature and voltages. The input
voltage is the voltage that connects to the transceiver board and is
unregulated
.
This voltage is essentially the output from the power supply assembly. The output
voltage is read after a 10 V dc regulator on the transceiver board.
Serial Number
This screen displays the serial numbers of the
transceiver
boards
. These numbers
will not match the serial number on the serial number label on the radio. If the radio
is not equipped with a second transceiver board, one of the lines will read “NOT
EQUIPPED.”
Software Revision
This screen displays the internal software part number and version number.
GROUP 4—EVENT LOG
Event Log
This screen shows the events logged on the
active
transceiver board. In many
cases, the events leading up to a failure can be reviewed to help determine the
cause of a problem. The event log number, date and time of the event, and a
description of the event are shown.
This screen shows the most recent log when first entered. Use the up/down arrow
buttons to scroll through the stored history of events.
Clear Logs
This screen is used to erase
all
events from the event log.
