Intercom Keys: Assignable for several types of oper-
ation, including talk only, listen only, talk with
auto-listen, and all-call (where activating the key
also activates all keys to the left of that key). Keys
feature momentary or latching operation. For mo-
mentary operation, the operator presses and holds a
key while communicating, then releases it when
finished. For latching operation, the operator taps a
key to turn it on, then taps it again to turn it off.
Latching can be disabled via an options switch (13)
or from ADAMedit or ZEUSedit.
