All service and tuning procedures are performed from the SERVICE
menu, which is selected by pressing F2 from the MAIN MENU.
Figure 2 illustrates how the RSS SERVICE screens are organized.
All SERVICE screens read and program the radio codeplug directly; you
do NOT have to use the RSS GET/SAVE functions to use the SERVICE
menus. You will be prompted at each screen to save changed values
before exiting the screen. RSS references in this manual are to
HT 1000 / JT 1000 RSS. Some slight differences may be noted it you are
using the MTS/MTX RSS.
The radio contains internal test modes that can be accessed from the
RSS. The test modes permit the service technician to easily select
various frequency, modulation, and transmit power combinations to
verify proper operation of the radio. The test modes can be used to
check both transmit and receive operation. From the Service Menu
press F6 to navigate to the TEST MODE screen.
The SERVICE screens introduce the concept of the “softpot”, an analog
SOFTware controlled POTentiometer used for adjusting all transceiver
alignment controls.

Do NOT switch radios in the middle of any
SERVICE procedure. Always use the EXIT key to
return to the MAIN menu screen before
disconnecting the radio. Improper exits from the
SERVICE screens may leave the radio in an
improperly configured state and result in
seriously degraded radio or system performance.
