transmission.
Interference from infrared communications
between other devices or from direct sunlight is
present.
Solution
Insert the batteries with the correct polarity
orientation.
Replace the batteries with new ones.
Clean the 3 and # terminals with a cotton swab.
Insert batteries, or change the PWR SOURCE
setting.
Use the same channel setting on both the
transmitter and receiver.
Use the same compander mode setting on both
the transmitter and receiver.
Use the same channel setting on both the
transmitter and receiver.
Refer to the operating instructions of the
connected device, and perform proper
connections.
Two or more transmitters cannot be used on the
same channel. Refer to the frequency list stored
on the supplied CD-ROM, and reconfigure the
channel on each transmitter.
The channel plan is set so that no signal
interference occurs when two or more transmitters
are used simultaneously. Set each transmitter to a
different channel within the same channel group.
Use the channels separated by at least two
channels (250 kHz).
Set the channel on the receiver to a channel for
which the RF indicator does not light, or use the
Clear Channel Scan function to switch to a
channel without interference. Then, set the
transmitter to the same channel as the receiver.
If using two or more transmitters, change to a
channel group that is not affected.
Set the channel on the receiver to a channel for
which the RF indicator does not light, or use the
Clear Channel Scan function to switch to a
channel without interference. Then, set the
transmitter to the same channel as the receiver.
If using two or more transmitters, change to a
channel group that is not affected.
Reduce the distance between the infrared receptor
on the transmitter and the infrared transmission
port on the receiver to within about 20 cm (8 in.).
The transmitting distance is reduced when
interference from strong sunlight, for example, is
present. Place the transmitter and receiver as
close to each other as possible.
