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. 87 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.
