ALE LINKED TO ADDRESS DISPLAYED ON LINE 2
This state indicates that the radio is linked to another ALE radio. The
ALE address listed on the second line (Figure 3-20) is the address of
the other ALE radio or the ALE net or group. An audible alert is gen-
erated and the Remote Lamp discrete is set when the link occurs.
The Remote Lamp discrete will be reset on the first activation of the
microphone key or any key or knob action. The operator hangs up
(unlinks) by pressing the SCAN key. On hang-up the radio returns to
the ALE idle state.
ALE RECEIVING AMD MESSAGE
This state (Figure 3-21) indicates that an AMD message is being or
has been received. The message scrolls across the display as it is
being received. The message will remain on the display for 15 sec-
onds or until the operator removes it by pushing a key or initiating
another action. An audible alert is generated, the Remote Lamp dis-
crete is set and the message flag (flashing M) will be displayed to
inform the operator of the message. The message flag will be
removed if a key is pushed while in the MsgRcv state.
