7.3.4.3.2 ALE Receive Operation
ALE Receive operation places the RT-9000 B ’s Receiver and ALE system in a mode that permits the RT-
9000 B to monitor and automatically respond to ALE calls from other Network Stations. The RT-9000 B
MUST BE set in Receive scan (‘RX-ALE’) mode for these capabilities to function. Perform the following steps
to enable ALE Receive scanning and operation:
1.
Depress the '*'/‘ALE’ key at 1 as shown in Figure 7.3.4.13. The Feature Menu shown in this same
figure will appear after the key is depressed.
2.
Confirm or select the correct Channel Group as described in the previous section (7.3.4.3.1).
3.
Depress the ‘RX –ALE’ key at 4 to start the ALE Receive scanning process. The Operational Display
may initially display a ‘PLEASE WAIT’ message for approximately 7-10 seconds immediately following
‘RX-ALE’ key depression. This message will automatically clear and change to ‘ALE RECEIVE’ with all
other normal Receive information disappearing. After Receiver scanning begins, the ‘TX-ALE’ and ‘RX-
ALE’ selections in the Feature Menu Display will also disappear.
4.
After the ‘ALE RECEIVE’ message appears in the Operational Display, the Receiver will begin
scanning. The operating frequency and Channel information sections of the Operational Display will
begin changing approximately every 1/2 second to indicate the instantaneous Receiver settings during
Receiver scanning.
RT-9000 B ALE Receive operation is designed to receive and to appropriately react to ALE calls from other
Network stations. The RT-9000 B will respond to the four (4) supported calling methods previously specified.
The ALE system automatically monitors all incoming ALE calls that are addressed, or apply, to any of your
station SELF IDs for each established ALE Network. This capability DOES NOT require any ALE Network
selection nor operation action for proper operation.
RT-9000 B responses to received ALE calls are covered in detail for each supported calling method later in
this section.
To cause Receiver scanning to stop, depress either the ‘END’ key or the ‘MORE’ key on the Feature Menu.
No other choices appear on the Feature Menu Display.
