Differences between semi-automatic and manual
Semi-automatic: When no op-
eration is performed, the
transceiver automatically
sends an Unable to comply acknowledgement 4.5 min.
after the call is received.
Manual: When no operation is performed after receiving a
call, NO acknowledgement is transmitted.
When full automatic (FA) is selected in SET mode
(p. 21):
The transceiver automatically replies to the call in one of
two ways, depending on the
auto acknowledge setting in
SET mode (p. 21).
When able to comply is set (Ab),
the transceiver automatically
transmits an able to comply ac-
knowledgement and then selects
the channel as specified by the
calling station for voice communications.
When unable to comply is set
(Un), the transceiver automati-
cally transmits an unable to com-
ply acknowledgement and
remains on channel 70.
