Desk Set Button Panel
Transmit Button and LED : The red
TRANSMIT
button is
used to place the desk set in the transmit mode and to
initiate voice transmissions. The
TRANSMIT
LED, located
to the left of the button, illuminates steadily when
transmitting, and flashes when a parallel desk set is
transmitting.
Monitor Button and LED : The
MONITOR
button
(CTCSS/CDCSS disable) is used to place the radio in the
monitor mode. This disables coded squelch and prevents
“running over” other user’s communication. The
MONITOR
LED, located to the left of the button,
illuminates when monitor is activated.
Volume Buttons: The units contain two buttons labeled
VOLUME
imprinted with up and down arrows. They are
used to increase and decrease the local speaker volume and
microphone levels. They are also used for special
applications.

available on the IPE2500A-MLS.
