Confirming Correct Installation
The transmitter’s TX LED (6) will flash
when a microphone or line level signal is
broadcast by the transmitter. If “TX” does
not flash, turn the audio input gain control
clockwise. This will increase audio level
and cause “TX” to flash along with the
program source. When “TX” is flashing,
the transmit ter is broadcasting properly.
Test the trans mit ter with an ALD-800
receiver. This pro ce dure is explained in
the receiver instructions.
Note: For the best performance, and to minimize
the possibility of interference from another source,
we suggest you experiment to find the minimal
height the antenna must be extended in order to
perform well in your particular environment.
Channel Selection
Channel selection is controlled by
DIP-switches inside the trans mit ter.
The system is preset at the factory.
Changing the channel can be done
quickly by any qualified service tech ni cian.
Contact your dealer or the Nady Customer
Service Department for details.
