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.
CTL
:
CTL
is used in conjunction with other buttons to provide secondary key functions.
IC
: The
IC
button allows communication between desk set users without transmission over the radio air
waves. When this button is pressed and held, microphone audio is routed to the line without activating
the radio transmitter. If using the handset, it is not necessary to press the handset PTT. The
IC
button
will serve as the PTT. Other desk sets in parallel will hear the audio automatically.
Keypad Buttons:
The numeric keypad is used for the selection of a desired frequency and page capcode
entry. See the “Operation” section of this manual for further information.
LCD Display:
Each of the desk sets includes a backlit 2
16 character LCD display for operator
information.
Signaling Buttons:
Refer to the diagram above for the location of the front panel buttons. The following
paging buttons are used for paging and initiating alert tones:
ALERT
SELECT
PAGE
DOWN
CLEAR
UP
The function and operation of each of the paging buttons is discussed in the “Operation” section of this
manual.
SELECT
, in addition to being used in the various signaling modes, also allows entry into the frequency
selection mode. This is useful when direct DTMF mode is enabled and the operator must change the
frequency of the base station.
N
OTE
:
This method of entry into the frequency selection mode is not
available on the IPE2500A-MLS.
Programmable Buttons:
The
PB1
,
PB2
,
PB3
, and
PB4
programmable buttons can each be configured to
perform two separate functions. Depending on its configuration, the selected button illuminates when it
is pressed. It continues to be illuminated until a different button is pressed.
