The saved call list shows all ten storage locations. If no calls have been received, the saved call list will be
empty and the pre-stored list will be available upon entering the individual call mode.

When in the saved call list, pressing MENU toggles the time stamp ON and OFF. The time stamp
indicates how long ago the call was received. The display indicates this information as HH:MM:SS where
HH = hours, MM = minutes and SS = seconds.

When in the pre-stored list, pressing MENU toggles the Logical IDentification (LID) on and off.

9.11.3 Sending an Individual Call

The following procedures describe how to initiate and complete an individual call.

1. To select a previously stored individual, select the I-Call mode from the menu or press IND followed

by the

ramp control to scroll through the list of stored individuals. The selection mode rules

apply. While in the individual call list, the menu key will toggle the display between the call name
and the unit ID number. If the individual is not stored in this list but the individual’s unit ID is known,
it can be entered directly from the keypad.

2. Press the PTT button; the radio performs the necessary signaling to obtain a communication channel.

When the signaling is complete and the radio is clear to transmit, TX indicator turns ON and the
channel access tone sounds. Line 1 shows the called individual's name if found in the list of stored
individuals or ID followed by the logical ID number of the unit being called. The message *INDV*
displays on line 2. Proceed with the message.

9.12 SCAT OPERATION

A SCAT™ (Single Channel Autonomous Trunking) System operates with the same set of features as a
standard EDACS system. The only significant user change relates to the BSY indicator. Since only one
channel, operating as both control and working channel, exists in a SCAT System, the BSY indicator will
be ON when the SCAT channel is in the working channel mode. When the transmission on the channel is
completed, the indicator turns OFF and indicates the return of SCAT control channel signaling.

9.13 TELEPHONE INTERCONNECT CALLS

9.13.1 Receiving a Telephone Interconnect Call (Trunked Mode Only)

Receiving a telephone interconnect call is identical to receiving an individual call. See the DTMF
Overdial Operation section if access to services requiring "over-dial" is needed. Overdial operations are
available for any special call whether it is an individual call or a telephone interconnect call.
