A short mid-pitched alert tone sounds after keying the
radio (Push-To-Talk button is pressed). This indicates the radio
has been assigned a working channel or that the radio is trans-
mitting on a conventional channel and voice communication may
begin immediately. In conventional mode, this tone may be de-
layed after the PTT button is pressed due to GE-STAR signalling
(if enabled through programming).

talk; immediately press the PTT button to keep the assigned
channel.

whenever a channel becomes available (see Autokey).
