NOT have to use the RSS GET/SAVE functions to use the SERVICE menus.

C a u t i o n

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.
