Type 99 is Ericsson’s proprietary method for in-band, two-tone
sequential signaling. It is a conventional signaling protocol used to
control the muting and unmuting of a radio. This signaling is commonly
used for selective calling of individual units or groups of units in a
conventional system. Type 99 is typically used in paging operations,
where a dispatcher is able to select which radio or radios are to be
selectively called.

If Type 99 has been setup, the radio can decode individual, group and
supergroup paging calls. When the radio decodes an appropriate Type
99 decode sequence, an alert sounds, the PG icon flashes and the radio
enters the Monitor mode.

1.

 

Turn scan OFF. The radio cannot receive selective
calls with scan ON. When scan is enabled, the radio
automatically switches to the Monitor Mode and
Type 99 decode is disabled.

2.

 

Select the proper system and channel as described in
the Basic Operation on page 14.

3.

 

When the radio receives a selective call:

À

 

The green TX/RX indicator will turn ON to
indicate the radio is receiving a carrier.

À

 

For an individual call, a single ½ second tone
will sound to indicate the call is an individual
call.

For a group call, two short tones will sound to
indicate the call is a group call.

For a supergroup call, three short tones will
sound to indicate the call is a supergroup call.
