8.22 INDIVIDUAL CALLS
8.22.1 Receiving and Responding to an Individual Call
When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the
assigned working channel and displays . The first line on the display shows the logical ID number of the
unit sending the message, or the associated name if the ID number is found in the individual call list. The
radio can be programmed to ring when an individual call is received. If enabled, the ring begins five
seconds after the caller un-keys and will continue until the PTT button, the button or the individual call
mode is entered.
The volume of the ring is adjustable through the volume control levels.
If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call
will automatically be directed to the originating unit. If a response is not made before the call-back time-
out, the radio will return to normal receive display, and
*WHC*
will appear on the first line of the LCD.
To respond after the call-back time-out, press the key. The radio's display will show the callers ID on
the first line and
WHCI=1
on the second line. Pressing the PTT button at this point will initiate an
individual call back to the original caller.
The radio stores the IDs of the last 10 callers in the Calls Received List as shown. Individual calls are
stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The
most recent call is stored in position 1, the second most recent call is stored in position 2, etc.
Figure 8-11: Calls Received Lists
To access the Calls Received List, press the key twice. Use the or buttons to scroll through
the list. Pressing the key will display the time elapsed since the call was received. After pressing
the display will appear similar to Figure 8-12.
