All SERVICE screens read and program the radio codeplug directly; you do NOT
have to use the RSS GET/SAVE functions to program new tuning values.
CAUTION
!
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.
The SERVICE screens use 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 6-8.
