Precautions
Table of Contents
On operation
· The unit must be used within a temperature range of 0°C to
40°C. Avoid using the unit for extended periods at
extremely high temperatures or placing it in direct sunlight,
especially outdoors because this may damage the finish of
the case. Never install the unit on or near a heat source,
such as lighting equipment or power amplifiers.
· Avoid using in very humid or dusty places, because such
use may shorten the life of the unit.
· To avoid degradation of the signal-to-noise ratio, do not
use the unit in noisy places or in locations subject to
vibration, such as the following:
-- near electrical equipment, such as motors, transformers
or dimmers
-- near air conditioning equipment or places subject to
direct air flow from an air conditioner
-- near public address loudspeakers
-- where adjacent equipment might knock against the unit
· Switching lights on or off may produce electrical
interference over the entire frequency range. Position the
unit and the wireless microphones so that interference is
minimized.
· The unit 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 unit with a dry, soft cloth. Never use thinner,
benzene, alcohol or any other chemicals, since these may
damage the finish.
