When holding the microphone, do not hook your fingers
on the antenna, or touch or cover the antenna with your
hands.
Doing so can weaken the signal, resulting in noise.
•
The unit is designed for use in an ambient temperature
range of 0°C to 50°C (32°F to 122°F).
•
Do not place the unit on or near a heat source such as
lighting equipment or a power amplifier, or in a place
subject to direct sunlight or excessive moisture. In such
places, the external finish or internal parts of the unit may
be damaged.
•
If the unit is used in a very humid or dusty place or in a
place subject to an active gas, clean its surface as well as
the connectors with a dry, soft cloth soon after use.
Lengthy use of the unit in such places or not cleaning it
after its use in such places may shorten its life.

When cleaning the unit, never use organic solvents such
as thinners or benzine, which will damage the finish of
the unit.
•
The unit has been factory adjusted precisely. Do not
tamper with its internal parts or attempt to repair it.
