3.5
Dual
Watch
Because
the
KRT2
radio
contains
only
one
receiver,
DUAL
watch
is
achieved
by
alternating
between
the
active
and
standby
frequencies.
The
DUAL
button
activates
and
deactivates
the
dual
watch
function.
Deactivation
can
also
take
place
by
pressing
either
the
FREQ
or
MEMORY
buttons.
The
frequencies
to
be
watched,
should
be
selected
prior
to
the
DUAL
watch
selection.
Scanning
of
frequencies
is
only
possible
when
differentiating
between
radio
noise
and
radio
transmissions.
This
can
be
achieved
with
the
squelch
system
set
to
a
value
of
02
or
higher.
There
must
be
radio
noise
suppression
in
order
to
recognize
reception.
SQ
must
be
02
or
higher.
When
DUAL
watch
is
activated,
DUAL
is
displayed
on
the
lowest
line.
The
pointer
next
to
the
DUAL
display
indicates
the
frequency
on
which
there
is
reception.
The
Active
frequency
always
has
priority,
so
the
receiver
remains
on
the
Active
frequency
as
long
as
there
is
reception
on
the
Active
frequency.
When
there
is
no
reception
on
both
the
Active
frequency
and
the
Standby
frequency
the
receiver
scans
both
frequencies
5
times
per
second.
When
there
is
reception
on
the
Standby
frequency
the
receiver
stays
on
the
Standby
frequency,
however
it
switches
to
the
Active
frequency
every
2
seconds
for
0.3
seconds.
When
reception
is
detected
on
the
Active
frequency
the
receiver
stays
on
the
Active
frequency.
