Toa YW-7000 - Manual (Page 2)

2. GeNeRAL DeSCRIPTION
The YW-7000 is an antenna booster designed for use to compensate for high frequency loss (cable loss) that occurs when
the antenna cable is extended.
It is used in combination with the optional YW-7520 or YW-7570 Wireless Antenna.
Since power is supplied from the antenna input terminal of the wireless tuner, the YW-7000 operates by simply connecting
the antenna cable to it.
3. HANDLING PReCAUTIONS
• The unit cannot be used with a direct mount L-type antenna.
• Do not install the unit at following locations. Doing so may cause damage to the unit.
· Locations directly exposed to rain such as outdoors or under the eaves.
· Locations with high humid or dust.
· Locations exposed to the direct sunlight or near heaters.
· Locations generating sooty smoke or steam.
• Do not use countersunk head screw to mount the unit, as the screw widens the mounting hole, causing damage to the
unit.
4. CONNeCTION
Notes
• Only 1 unit can be connected per antenna.
• If the unit is connected in reverse (antenna side and tuner side), it will not operate.
