Display contrast

The LCD contrast can be adjusted through 9 levels.

(default: 5)

D

Duplex direction

Sets the duplex direction. The displaying frequency shifts the
programmed offset frequency (below) when monitor function
is in use (pushing [MONI•T/T-SCAN]).

• OFF : Simplex operation. (default)
• DUP– : The displaying frequency shifts down during

monitor.

• DUP+ : The displaying frequency shifts up during moni-

tor.

D

D

Offset frequency

Sets the duplex offset frequency for each frequency band in-
dependently within 0 to 1000 MHz range. During duplex op-
eration (DUP– or DUP+), the monitoring frequency (pushing
[MONI•T/T-SCAN]) shifts the set frequency.

The default value may differ according to the selected fre-
quency band 

(before accessing set mode)

and receiver version.

The selected tuning step in VFO mode is used for setting
the offset frequency.
