Receiving an Acknowledgement
Depending on the signalling format used, the sending radio may look for an
acknowledgement from the receiving field unit on Call Alert and radio check calls.
The sending radio will show an “A” and four alert tones will sound if the field unit
received and acknowledged the call. It will try to reach the field unit five times and,
if unsuccessful, a “-A” will be displayed and a low tone will sound to indicate no
acknowledge.
Exiting the Call LIst
The Select or Call button can be used to exit the signalling call list. Repeated
pressing of the Select or Call button takes one through the sequence of call
letters to the channel display for normal operations.
Six channel radios also have an Exit or H/L button. A single press of the Exit or
H/L button will take the radio out of signalling and return to the channel display at
any time.
Receiving an Emergency Alarm
When an emergency alarm is received by the control unit, an alert tone will
sound. The display will alternate “EE” and the ID number of the radio sending the
emergency.
Five different emergency IDs can be queued. However, the first ID to be received
will be displayed until it is cleared. Then the next ID in the queue will be displayed
until each has been displayed and cleared.
Clearing an Emergency Alarm
To prevent accidentally losing an incoming emergency, the clearing of an
emergency alarm has been designed as a two-step process. First, the alert tone
must be cleared by any button press on the radio.
The second step requires the use of an external push button or footswitch. Only a
press of the external switch will clear the emergency display.
