YW-4500
WALL-MOUNTED WIRELESS ANTENNA
INSTRUCTION MANUAL
• Be sure to securely mount the unit on the wall or ceiling that is robust enough to stand the antenna weight.
Failure to do so may drop the antenna, causing personal injury and/or property damage.
• 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.
• 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.
• Use nuts and bolts that are appropriate for the ceiling's or wall's structure and composition. Failure to do so may
cause the unit to fall, resulting in material damage and possible personal injury.
• Do not touch a plug or antenna during thunder and lightning, as this may result in electric shock.
• Leave the installation of an antenna to your TOA dealer because the installation requires expert knowledge. The
falling of an antenna may cause personal injury.
• 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.
