Receiving Calls
When power is applied, the IPE2500A is in the receive mode, allowing receive audio to be heard through
the speaker or handset. It is always in receive mode unless the unit is transmitting, or a parallel desk set
is transmitting (parallel mute function enabled).
The IPE2500A Desk Set contains an internal or local speaker and a handset speaker that operate as
follows:
 When the handset is in the cradle, or on-hook, receive audio is heard on the internal speaker. In some
operational modes, this can be changed, i.e., muting the speaker during TX of a parallel desk set.
 When the handset is off-hook, receive audio is routed to the handset. By using the front panel
buttons, you may optionally select to hear audio through the local speaker in addition to the handset.
Initiating Calls
Before initiating a call, press the
MONITOR
button to verify that the radio channel is clear. The
MONITOR
button remains illuminated until a transmit function is initiated. This operation is typically
required when a community or shared repeater is in use. Always allow time for the radio channel to be
established. In addition, if the unit is configured to generate PTT IDs and to generate side tone, a tone
will be heard during the PTT pretime and PTT generation. A voice delay can be programmed via the
CARD Suite software to eliminate this waiting time if no PTT ID is used.
To initiate a call, press the
TRANSMIT
button, the handset push-to-talk (PTT) pressbar, or an accessory
PTT button. When the desk set is transmitting, the
TRANSMIT
LED illuminates. The
TRANSMIT
button
or handset PTT bar must be held down while talking to the radio user and released to listen. When the
transmission is completed, the
TRANSMIT
LED extinguishes and the desk set returns to the receive
mode.
