Telephone Configuration
The GMA 35 provides a 2-way telephone interface. Operation depends on
the state of the
TEL
key and ICS mode. Telephone communication is much like
using the intercom, allowing both parties to talk at once.
The TEL channel may be disabled in Configuration mode. Contact a Garmin-
authorized service center for details.
1. While viewing the Intercom Setup page, touch the
Telephone
key to set its configuration.
