Warm-up delay (▲▼,ENT)
For fine adjustment of the Internal 10 MHz reference oscillator, use the 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.

28 CHARACTER TST MESSAGE

then use the ST arrow keys to select the character for that position.
Only the bottom line is available (28 characters). The following characters are available:
[Space] ( ) * + - , . / 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.
