Storage/usage location
Do not use or store the unit in the following locations.
Malfunction may occur as a result.
● Location outside the allowed operating temperature
range (0 I to 40 I) where the temperature may
become extremely hot or cold.
● Location outside the allowed operating humidity range
(20 % to 80 %) where the humidity is high.
● Location with strong magnetic force such as from a
transformer, motor, etc.
● Location with presence of electric waves such as from a
transceiver, mobile phone, etc.
● Location that is dusty or sandy.
● Location with strong vibrations.
● Location with condensation.
● Location where radiation, x-ray or corrosive gas is

Handling
To prevent the internal temperature from rising, do not stack
units when using.
Do not place the unit on its side.
Handle the unit with caution and do not apply excessive
force.
Wipe the unit with a soft cloth.
The surface may fog or even melt when wiped with
benzene or paint thinner. For stubborn dirt, use neutral
detergent diluted in water and then dry wipe.
To completely cut off the power, disconnect the power cable
from the wall outlet or remove the power cord from the AC
adaptor.
Installation
Be sure to ground the unit.
Place the unit near a wall outlet.
Always use the specified (included) power cord and AC
adaptor.
Use of a cord other than that specified or a cord that has
been damaged may result in fire or electrical shock.
Do not use power cord or AC adaptor other than with this
unit.
Do not place heavy objects such as a monitoring television
on top of the unit. Malfunction may occur as a result.
About the echo canceller
The echo canceller of the unit is provided for the prevention
of howling. However, repeated echoing of sound other than
from a VN-E4 may not be suppressed sufficiently.
When using a speaker and a microphone at the same time,
place them apart, change the direction of the microphone
or take caution so that the playback sound from the speaker
is not picked up by the microphone.
When using a camcorder with audio AGC (Auto Gain
Control), the echo canceller may not work properly. Please
turn off the AGC.
If the AGC feature cannot be turned off, use a separate
microphone amplifier with no AGC.
When not using the unit for a long time, turn the power of
the unit off for conserving energy.
About electrical interference
When using the unit near a television, radio receiver or
transceiver, screen images may become disturbed or noise
may be heard. In this case, try the following:
● Place the unit away from radios and televisions or
change the direction of the unit.
● If an indoor antenna is used, change the direction or the
location of the antenna.
● Use a wall outlet other than the one used for radios,
televisions, etc.
● Install a commercially-available noise filter between the
wall output and power plug.
