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 on or near heat sources, such as
lighting equipment, power amplifiers.
• 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

• 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.
• The unit has been factory adjusted precisely.  Do not
tamper with its internal parts or attempt to repair it.
