on Operation
On Usage and Storage
• The WRR-855S must be used within the
temperature range of 0°C to 50°C (32°F
to 122°F).
• Avoid using for an extended period of
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 unit on or near heat sources,
such as lighting equipment, power
amplifiers.
• The tuner unit 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 unit.
• To avoid degradation of the signal-to-
noise ratio, do not use the tuner unit 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 unit.
• The switching of lights may produce
electrical interference over the entire
frequency range. Position the tuner unit
and the wireless microphone in a place
where such interference is at minimum.
• The tuner unit has been factory-adjusted
precisely. Do not tamper with its internal
parts or attempt to repair it.

On Cleaning
Clean the tuner unit with a dry, soft cloth.
Never use thinner or benzine, since these
will damage the finish.
Keep a distance between
eyes and antenna
When looking into the upper-panel display
or making settings with the buttons, be
careful to keep a sufficient distance
between your eyes and the tuner unit.
