Step 3 Placing the receiver
For best reception, we recommend that the receiver be placed within the line of
sight from the transmitter. If possible, the receiver should be placed right side up
with its front toward the transmitter.
Example 1 below shows the optimum placement of the receiver. If no line of sight is
possible, place the receiver such that there is the minimum possible number of
walls and obstacles between the transmitter and receiver.
You can mount the receiver vertically as shown in Example 2 by using the 2 screw
openings at the bottom. In this case, the operating range is reduced compared to
mounting the receiver right side up.
The receiver incorporates a directional antenna which prefers signals transmitted
toward the front of the receiver. Therefore, the front of the receiver should always
be facing toward the direction of the strongest transmitter signal.
Note: This product will not work properly from within an enclosed metal cabinet.

extremely short
Strong interference
In s ome c as es, there may be strong
interferenc e preventing proper reception
of the audio si gnal which can be caused
by 5.8 GHz cordless telephones or 5.8
GHz wireless networks . Either eliminate
the interference, l ocate the base unit of
the cordless phone i n another room, s et
the wi reles s network to use the 5.1 GHz
frequenc y band rather than 5.8 GHz ,
relocate the trans mitter, relocate or
reori ent the receiv er to improve reception.
Audi o will drop out if there are too many
obstacles between the transmitter and the
rec eiver, try relocating the transmitter or
rec eiver to improve rec eption.

READ THESE SAFETY INSTRUCTIONS CAREFULLY AND
HEED ALL WARNINGS IN THIS MANUAL.
POWER SOURCE
To product malfunction, and to protect against electric shock, fire or personal injury,
please observe the following:
• This product has been designed to work with 120-volt AC current using
the supplied AC adapters. Connection to a line voltage other than that or
use of non-compatible AC adapters may create a safety and fire hazard
and may damage the product.
• Do not run power cords under rugs or carpets or place heavy objects on
them.
• Damaged or deformed power cords are hazardous and should be
replaced immediately by a qualified service technician.
LOCATION
• Do not use this product outdoors or in cars.
• Do not place this product in direct sunlight, or near heat sources.
• Keep this product away from strong magnetic objects.
VOLUME CONTROL
• Do not turn up the transmitter volume while listening to a portion with very
low level input or no audio signal to avoid damage to your speakers
during a peak level audio portion.
• Turn the transmitter volume control to minimum prior to connecting or
disconnecting the transmitter or receiver and prior to switching audio
sources as this may cause loud clicks which can damage your speakers.
CARE
• Do not place any object containing water or other liquids on this product.
• Do not remove the cabinet. Touching parts inside the cabinet could result
in electric shock and damage to the product.
