TABLE OF CONTENTS
2
When Installing the Unit
• Do not expose the unit to rain or an environment
where it may be splashed by water or other liquids,
as doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the
unit. Using a voltage higher than that which is
specified may result in fire or electric shock.
• Do not cut, kink, otherwise damage nor modify the
power supply cord. In addition, avoid using the
power cord in close proximity to heaters, and never
place heavy objects -- including the unit itself -- on
the power cord, as doing so may result in fire or
electric shock.
• Avoid installing or mounting the unit in unstable
locations, such as on a rickety table or a slanted
surface. Doing so may result in the unit falling
down and causing personal injury and/or property
damage.
• To prevent lightning strikes, install the unit at least
five meters away from a lightning rod, and yet
within the protective range (angle of 45°) of the
lightning conductor. Lightning strikes may cause a
fire, electric shock or personal injury.
• Since the unit is designed for in-door use, do not
install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal
injury. Also, when it gets wet with rain, there is a
danger of electric shock.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately switch off the power, disconnect
the power supply plug from the AC outlet and
contact your nearest TOA dealer. Make no further
attempt to operate the unit in this condition as this
may cause fire or electric shock.
· If you detect smoke or a strange smell coming
from the unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged (exposure of
the core, disconnection, etc.)
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
your nearest TOA dealer.
• Do not place cups, bowls, or other containers of
liquid or metallic objects on top of the unit. If they
accidentally spill into the unit, this may cause a fire
or electric shock.
• Do not touch a plug or antenna during thunder and
lightning, as this may result in electric shock.
The servicing instructions are for use by qualified
personnel only. To reduce the risk of electric shock
do not perform any servicing other than that
contained in the operating instructions unless you
are qualified to do so. Refer all servicing to qualified
service personnel.
When Installing the Unit
• Never plug in nor remove the power supply plug
with wet hands, as doing so may cause electric
shock.
• When unplugging the power supply cord, be sure
to grasp the power supply plug; never pull on the
cord itself. Operating the unit with a damaged
power supply cord may cause a fire or electric
shock.
1. SAFETY PRECAUTIONS
• Be sure to read the instructions in this section carefully before use.
• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.
• We also recommend you keep this instruction manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
WARNING
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
CAUTION
3
• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.
• When moving the unit, be sure to remove its power
supply cord from the wall outlet. Moving the unit
with the power cord connected to the outlet may
cause damage to the power cord, resulting in fire or
electric shock. When removing the power cord, be
sure to hold its plug to pull.
• Leave the installation of the optional YW-4500
antenna to your TOA dealer because the
installation requires expert knowledge. Improper
installation may cause the antenna to fall, resulting
in personal injury or electric shock.
• The socket-outlet shall be installed near the
equipment and shall be easily accessible. A fire or
electric shock may result.
• Install the AC-DC adapter in well-ventilated
locations. Do not install the adapter in a confined
space such as a book case or similar unit . In
addition, keep over 1 m space above the adapter.
When the Unit is in Use
• Do not place heavy objects on the unit as this may
cause it to fall or break which may result in
personal injury and/or property damage. In
addition, the object itself may fall off and cause
injury and/or damage.
• Make sure that the volume control is set to
minimum position before power is switched on.
Loud noise produced at high volume when power is
switched on can impair hearing.
• Use the dedicated AC-DC adapter for the unit.
Note that the use of other adapter may cause a
fire.
• If dust accumulates on the power supply plug or in
the wall AC outlet, a fire may result. Clean it
periodically. In addition, insert the plug in the wall
outlet securely.
• Switch off the power, and unplug the power supply
plug from the AC outlet for safety purposes when
cleaning or leaving the unit unused for 10 days or
more. A fire or electric shock may result.
2. GENERAL DESCRIPTION
The WT-4820 is a diversity tuner that can accept up to two wireless tuner modules of UHF band (WTU-4800).
It can be mounted in an EIA 19-inch equipment rack using an optional MB-WT3 or MB-WT4 Rack Mount
Bracket Kit.
3. FEATURES
• Half-rack mount size
• Easy-to-change channel number accessible from the front.
• Front-loading modular construction permits easy installation of the WTU-4800 tuner module even after the
unit is rack-mounted.
• Antenna outputs connect an additional tuner unit, expanding the system to maximum 4 channels (2 each
tuner modules incorporated) without need for extra antenna mixers/distributors.
• A mix input mixes outputs of two or more tuner units into one output signal.
4. HANDLING PRECAUTIONS
• Use only WM-4200 series and WM-4300 series Wireless Microphones. Other wireless microphones cannot
be used.
• Turn the power switch off after use.
• When mounting in an equipment rack, place the unit away from high-temperature equipment.
• When using two or more wireless microphones at the same time in the same location, set them to different
channels and keep them at least 50 cm from each other.
• Keep the wireless microphone at least 3 m away from the antenna.
• Connect two antennas to the unit. Using a single antenna disables the diversity effect.
• Keep the unit as far away as possible from fluorescent lamps, digital equipment, computers, and other
equipment generating high-frequency noise.
• To clean the unit, switch the power off, then wipe with a dry cloth. When the unit gets very dirty, use a cloth
damped in a neutral cleanser. Never use benzene, thinner or chemically-treated cleaning cloth because
such volatile liquids could deform or discolor the unit.
