6.4.1.5 Common Functions
Some functionality is available regardless of whether a transceiver is operating in Tactical mode or ATC-
COM mode, such as volume control. The following sections describe operation that is common to both
Tactical and ATC-COM mode.
6.4.1.5.1 Test Function
When the operator presses and holds the TEST Transceiver-Menu button the active transceiver shall be
forcibly un-squelched for as long as the button is pressed. When the operator releases the Transceiver-
Menu button, the active transceiver shall resume its normal squelch operation.
6.4.1.5.2 Mute Function
When the operator presses the MUTE Transceiver-Menu button the active transceiver shall be muted if it
is not already muted, and shall become unmuted if it is currently muted. When a transceiver is muted,
no audio from that transceiver shall be audible.
6.4.1.5.3 Volume Adjustment
When the operator turns the volume knob, the volume adjustment dialog shall appear to adjust the
volume on the active transceiver. Figure 16 depicts the volume adjustment dialog after the volume knob
has been turned. Turning the volume knob clockwise shall increase the volume level, while turning the
knob counter clockwise shall decrease the volume level. The current volume level shall be displayed
within the dialog. The volume adjustment dialog shall automatically disappear when no knob turning
activity has occurred for more than 2 seconds.
When the operator pushes the VOL Transceiver-Menu button the volume adjustment dialog shall appear
to adjust the volume on the active transceiver. Touching the volume scale and sliding the pointer to the
left shall decrease the volume level, while sliding the pointer to the right shall increase the volume level.
The current volume level shall be displayed within the dialog. The volume adjustment dialog shall
automatically disappear when no touch pointer activity has occurred for more than 2 seconds.
