TTuunneerr ((AAuuttoo SSttaarrtt))

The internal antenna tuner has an automatic start ca-

pability which starts tuning if the SWR is higher than

1.5–3:1.

When “OFF” is selected, the tuner remains OFF even

when the SWR is poor (1.5–3:1). When “ON” is se-

lected, automatic tune starts even when the tuner is

turned OFF.

You can set the antenna connector selection to auto-

matic, manual or non-selection (when using 1 an-

tenna only).

When “Auto” is selected, the antenna switch is acti-

vated and the band memory memorizes the selected

antenna. See p. 46 for details.

When “Manual” is selected, the antenna switch is ac-

tivated and selects an antenna manually.

When “OFF” is selected, the antenna switch is not ac-

tivated and does not function. The [ANT1] connector

is always selected in this case.

AAuuttooAntenna switch is activated and the

selection is automatically memorized.

(default)

MMaannuuaallAntenna switch is activated.

OOFFFFAntenna switch is deactivated and

[ANT1] is always selected.
