2. 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.
1. IMPORTANT SAFETY INSTRUCTIONS
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water.
• Clean only with dry cloth.
• Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers)
that produce heat.
• Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider
than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are
provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet.
• Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
• Only use attachments/accessories specified by the manufacturer.
• Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with
the apparatus. When a cart is used, use caution when moving the cart/apparatus combination
to avoid injury from tip-over.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
• 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.
Thank you for purchasing TOA's Antenna Distributor.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.

• 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.
• 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.)
•
To prevent a fire or electric shock, never open nor remove
the unit case to modify 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.
3. GENERAL DESCRIPTION
The TOA Wireless Antenna Distributor WD-4800 is designed to be used in conjunction with a VHF/UHF band system for
sound reinforcement applications. It comes with two channels, in which two input signals are mixed and distributed to four
outputs. The WD-4800 also has four DC power distribution outputs.
4. HANDLING PRECAUTIONS
• When installing, keep the unit, receiving antennas, and antenna cables as far away as possible from fluorescent lamps,
digital equipment, personal computers, and other equipment which generate high frequency noise.
• Avoid installing the receiving antennas in close proximity to metal objects, such as iron frames and lockers. Keep the
antennas at least 30 cm away from the wall surface.
• Keep two antennas at least 3 m away from each other to obtain the optimum diversity effect, although this distance
differs depending on the construction and size of the room where they are installed.
• When cleaning the case, use a dry cloth. Never use benzine, thinner or other volatile liquids.
• 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.
• The socket outlet shall be installed near the equipment and shall be easily accessible.
• 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.
• 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.
• 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.
• 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.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.

2. ALLGEMEINE BESCHREIBUNG
Der Antennenverteiler WD-4800 wird in Kombination mit VHF/UHF-Funkmikrofon-Systemen eingesetzt. Zwei Eingänge
können gemischt und auf vier Ausgänge verteilt werden. Zusätzlich hat das Gerät Buchsen für die Spannungsversorgung
von bis zu vier WT-4800 Empfängern.
3. HINWEISE ZUM BETRIEB
• Bei der Installtion sollte auf ausreichenden Abstand zu Leuchtstofflampen, PCs und anderen Geräten geachtet werden,
die hochfrequente Störungen erzeugenden.
• Die Antennen sollten mindestens 30 cm Abstand zur Stahlbetonwand oder zu anderen metallischen Objekten
(Traversen etc.) haben.
• Die Vorteile eines Diversity Systems werden erst ab einem Mindestabstand von 3 m zwischen Sende- und
Empfangsantennen voll genutzt.
• Die Reinigung sollte mit einem feuchten Tuch erfolgen. Verwenden Sie keine Lösungsmittel, wie Benzin oder Verdünner
oder andere leichtflüchtige Flüssigkeiten.
