To clear the emergency, first press and hold the 

 button. While continuing to hold the 

 button, press 

the EMERGENCY button. (This will work if the radio is programmed to clear emergencies.) 

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. 

 

To access this list, press the 

 key twice. Use the 

 or 

 buttons 

 or 

 buttons to scroll through 

the list. Pressing the 

 key will display the time elapsed since the call was received. After pressing 

 an 

example of the display is shown in Figure 9-11:
