6.3. VOLUME ADJUSTMENT
The Volume Control adjusts the speech level at the radio speaker. The volume is
adjusted by the Volume Up and Volume Down buttons on the top of the SRM9022
Controller Microphone.
Note:- The radio may be programmed so that the volume cannot be completely
turned off.
6.4. RECEIVING (SINGLE CHANNEL SCREEN)
The radio will listen on the displayed Channel.
The Solid Speaker Icon will be displayed when a valid signal is being received and audio
will be heard at the loudspeaker.
An Outline Speaker Icon will be displayed if a signal is being received that is not
addressing this radio and, hence, is not audible. For example, another user group may
be having a conversation on another Talk Group when receiving in Selective Mute.
The analogue channel’s receive mute setting can be altered from the Mute Adjust
menu.
While on an Analogue channel, both P25 and Analogue FM transmissions will be
received.
While on a P25 channel, only P25 transmissions will be received.
To change channels, press the ▼ and ▲ keys while in the channel screen.
Zones can be changed from the Zone menu, see section5.2.
