The SERVICE screens introduce the concept of the "softpot," an analog
SOFTware-controlled POTentiometer used for adjusting all transceiver
alignment controls.
Each SERVICE screen provides the capability to increase or decrease the
'softpot' value with the keyboard UP/DOWN arrow keys respectively. A
graphical scale is displayed indicating the minimum, maximum, and
proposed value of the softpot, as shown in Figure 3.

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.
