The

11
(11

A2

as
shown
in
tables
from
pages
6
to
11.
The
wireless
channel
groups
other
than
group
00
are
designed
so
that
you
can
use
all
wireless
channels
of
any
one
group
simultaneously
within
the
same
UHF
wireless
microphone
system
without
causing
intermodulation.
It
is
therefore
recommended
that
you
make
it
a
rule
to
use
a
wireless
channel
group
other
than
group
00
unless
the
use
of
group
00
is
specifically
necessary.
Each
“wireless
channel”
is
represented
by
a
2-digit
TV
channel
number
and
another
2-digit
number,
for
example:
68-23.

The

depends
on
the

conditions.
To
eliminate
interference
or
noise,
please
note
the
following.
e
Do
not
use
two
or
more
wireless
microphones
or
transmitters
whose
wireless
channels
are
the
same.
e
If
there
is
a
TV
broadcasting
station
nearby,
to
avoid
possible
interference
from
its
broadcast,
do
not
use
that
station’s
channel.
e
The
number
of
wireless
channels
actually
usable
in
a
multi-channel
system
may
be
smaller
than
the
normal
capacity
of
that
system
if
there
is
interference
from
TV
broadcasting
or
other
RF
signals.
e
To
operate
two
or
more
UHF
synthesized
wireless
microphones/transmitters
using
the
same
wireless
channel
of
the
same
group,
ensure
that
the
wireless
microphones/
transmitters
are
at
least
100
m
(330

apart
as
far
as
they
are
installed
within

e
When

more
WRR-810As,
do
not
directly
put
one
unit
upon
the
other.

On operation
e The tuner must be used within the temperature range of
0°C to 50°C (32°F to 122°F). Avoid using for an
extended period time in extremely high temperature, or
the place subject to direct sunlight, especially outdoors,
because the finish of the case might be damaged.
Never install the tuner on or near heat sources, such as
lighting equipment, power amplifiers.
e The tuner is designed to be portable and is built to resist
humidity and dust. However, try to avoid using in very
humid or dusty places, because such use may shorten the
life of the tuner.
e To avoid degradation of the signal-to-noise ratio, do not
use the tuner in noisy places or in locations subject to
vibration, for example:
— near electric equipment such as motors, transformers or
dimmers
near air conditioning equipment or places subject to
direct air flow from an air conditioner
near a public address loudspeaker
in a location where adjacent equipment might knock
against the tuner.
The switching of lights may produce electrical
interference over the entire frequency range.
Position the tuner and the wireless microphone in a place
where such interference is at minimum.
e The tuner is precisely adjusted at the factory and no
adjustment before use is necessary. Do not touch the
inside of the unit or try to repair it by yourself.
On cleaning
Clean the tuner with a dry, soft cloth. Never use thinner or
benzine, since these will damage the finish.
