Refer to paragraph VII., F. Troubleshooting and
Repair to realign the radio.
F. Fastener Torque Chart
Table 17 lists the various fasteners by part number
and description, followed by the torque values and the
location where used. Torque all fasteners to the recom-
mended value when assembling the radio.
IX. TEST FREQUENCY MENU
The test mode is part of the diagnostics built into the
radio and is entered through the front panel program-
ming sequence. (See FRONT PANEL PRO-
GRAMMING AND ADJUSTMENTS in this manual, and
specifically, paragraph XVI. for password entry.)
After the password is successfully entered, the radio
enters a test mode where basic radio and signalling
measurements are made at three separate frequencies
across the band. The first six characters of the display
show the six least-significant digits of the selected
receive or transmit frequency, and the last two charac-
ters indicate the type of signalling or modulation
selected. For example, the first receive frequency upon
entry to the test mode is 935.0125 MHz and the sig-
nalling is carrier squelch. The display shows
"350125CS”. When transmitting, the display will change
to the transmit frequency. The three test frequencies
are:
The signalling types are shown in Table 18.
In test mode, press Volume to adjust volume. How-
ever, the volume display in test mode is in 256
