INSTALLING THE SECOND ANTENNA

The true diversity system requires two antennas for proper operation. You
can connect the supplied second antenna directly to the BNC connector on
the top of the receiver.

The antennas should be fully extended, and oriented as shown for the best
performance.

Or you can connect an RG58 cable to the BNC connector and the antenna, and
locate the second antenna farther away from the receiver. In some
locations, this provides better performance.

CONNECTING THE RECEIVER AUDIO OUTPUTS

To connect the receiver's LINE output to the LINE input of an amplifier,
tape recorder, or mixing board, use a shielded cable with phono-plugs on
both ends.

To connect the receiver's MICROPHONE output to the MICROPHONE input of an
amplifier, tape recorder, or mixing board, use a shielded cable with a 1/4
inch phone plug on one end and the appropriate connector (phone plug or XLR
connector) on the other end.

Follow the instructions in the owner's manuals for your other audio
equipment to make all other connections.

SETTING THE RECEIVER CHANNEL

You can set your receiver to one of eight channels. This lets you use more 
than one wireless microphone system in the same audio system.

Follow these steps to set the channel.

1.  Follow the instructions in the microphone's owner's manual to set the
    microphone's channel.

2.  Set the CHANNEL selector switch on the receiver to the same channel 
    as the microphone.

NOTE:  When using more than one wireless system with the same audio system,
       do not set any two wireless systems to adjacent channels. For
       example, if one wireless system is set to Channel C, do not set any
       other wireless system to Channel B or D. Two wireless systems set to
       adjacent channels will interfere with each other.

If you intend to use more than two wireless microphone systems in the same
location, follow these recommended channel combinations for the best
performance.

IMPORTANT:  Always use the STANDBY setting on your transmitter to mute a
            microphone. Using the STANDBY setting minimizes interference
            when you use more than one wireless system.

POWERING THE RECEIVER

You operate the receiver from the supplied 12-volt DC power adapter.

CAUTION:  Use only the supplied adapter. If you lose or damage this
          adapter, order a replacement from your local Radio Shack store.
          Other adapters could damage the receiver.

          Be sure the receiver's POWER button is out (OFF), then connect
          the adapter as shown.
