Warm-up delay (▲▼,ENT)

ST

arrow keys to edit

the value, then press

ENTER.

The range of accepted values is from –2048 to +2047.

IMPORTANT

The numbers displayed here do not correspond to an exact frequency
increment. The user should perform this fine adjustment while using an
external frequency counter connected to either:

a)

the internal 10 MHz reference, or

b)

the Tx Output set for CW, and an exact center frequency of – for
example – 1000 MHz.

To edit the Circuit Identification string, use the

arrows keys to select the position to edit,

then use the ST arrow keys to select the character for that position.

( ) * + - , . / 0-9 A-Z

Once the Circuit ID string has been composed, press

ENTER

to save.

Note: Backup devices in redundant groups do not have an ID. If plug-in devices are to be
grouped, the grouping should precede assigning IDs so the group can be named instead of the
individual devices.
