NOTE
The Automatic Reset allows the user to
define a reset schedule for the transmitter
after a shutdown condition. The schedule can
have up to five sequential levels, each with
their own user definable delay period (up to
24 hours) and subsequent instruction.
x
ENABLED (continue)
: attempts a reset
the denoted delay time after a shutdown
and then, if no reset occurs, continues to
the next item in the Fault schedule.
x
ENABLED (repeat)
: attempt a reset the
denoted delay time after a shutdown and
continues attempting (as necessary) after
each delay time. All subsequent items in
the Fault schedule default to
DISABLED
.
x
ENABLED (halt)
: attempts a reset the
denoted delay time after a shutdown and
then, if no reset occurs, stops attempting.
All subsequent items in the Fault
schedule default to
DISABLED
.
x
DISABLED
: no attempt to reset.
x
Waits the Fault 1 delay period (40 min)
x
Attempts to reset transmitter. If
successful, Automatic Reset schedule
will begin on Fault 1 next shutdown. If
unsuccessful, reset sequence continues
to Fault 2 item.
x
Waits the Fault 2 delay period (20 min)
x
Attempts to reset transmitter. If
successful, Automatic Reset schedule
will begin on Fault 1 next shutdown. If
unsuccessful, repeats Fault 2 item.

and press
Select
. The following message
is displayed. Press
Continue
to proceed.
NOTE
As the warning message indicates, ensure
that the transmitter is operating at the
minimum allowable modulation depth before
computing the thresholds. If the transmitter is
to operate in both PTT and Normal modes,
set up both thresholds, otherwise, set up only
the applicable threshold.
(i) The screen shows the minimum
allowable modulation for
PTT Inactive
(no voice) and
PTT Active
(voice).
x
The left column has side A values and
the right column has side B values.
-Before proceeding, make sure that you
have set the ident tone to the minimum
acceptable modulation depth with PTT
inactive, and again with PTT active.
-If this is a dual system, ensure tone
has been set correctly on both sides.
