How to listen to messages on the displayed channel -
The Solid Speaker Icon
will be displayed when a
valid signal is being received and audio can be heard
through the loudspeaker.
An Outline Speaker Icon
will be displayed if a
signal is being received that is not addressing this radio
and is not audible. For example, another user group
may be having a conversation on another Talk Group
when receiving in Selective Mute.
The analog channel’s receive mute setting can be altered from the Mute Adjust menu. While
on an Analog channel, both P25 and Analog FM transmissions will be received. While on a P25
channel, only P25 transmissions will be received.
6.6.1. RECEIVED INDIVIDUAL CALLS
Unanswered received individual calls addressed to the radio are stored in radio memory. The
caller unit ID may be viewed, answered and deleted by the user as desired.
A newly received individual call addressed to the radio will produce an intermittent alert tone
until any key is pressed.
If the caller unit ID of a newly received unanswered
call is already in the Stored Calls list, the old Stored
Call record of that unit ID will be replaced by the new
record and added to the top of the list.
To view/answer/delete received call records, the Stored
Calls screen is selected.
For further details of the Stored Calls Menu and functions see Section 5.7.
