Answering A Telephone Interconnect Call; Placing A Special Call To Another Radio; Receiving An Individual Call - Ericsson TRUNKED MDX Operator's Manual

Your MDX radio is capable of simplex (one way) conversation only.
The person you are talking to can hear you ONLY when you have the
PTT button pressed. You can hear the person on the telephone ONLY
when the PTT button is released.
If you leave the PTT button released for too long, the system will send
three beeps. When you hear these beeps, you have five seconds to press
the PTT button before the call is automatically terminated.
4. To terminate the call, momentarily press the CLR button or hang up
the microphone.

Answering A Telephone Interconnect Call

1. Receiving a telephone interconnect call is much like receiving an
individual call (refer to RECEIVING AN INDIVIDUAL CALL).
When the telephone call is received, the radio displays PHN CALL.
2. To terminate the call, momentarily press the CLR button or hang up
the microphone.
3. If you were out of the vehicle when the call came in, the display will
show "C*" or "*C" or P1 & P2 indicators will flash to indicate that
a call was received. If you select SPC CALL from the menu, the "C*"
or P1, P2 indicator, will go away if the call was a phone call. See
RECEIVING AN INDIVIDUAL CALL for more detail.

Placing A Special Call To Another Radio

1. Make sure the radio is turned ON, and the proper System has been
selected. Press the MENU button until the name SPC CALL appears
in the display. Press the GROUP/SEL + or - buttons until the desired
name appears in the display. The radio ID may be entered manually
if using the MDX System Model radio.
2. Press the PTT button and wait for the channel available tone before
talking.
3. When completed, release the PTT button and listen for any reply.
4. When your call is finished, press the CLR button or return the
microphone to the hookswitch. The previously selected Group name
appears on the display.
