Nady Systems ALD-800 owner manual Confirming Correct Installation, Channel Selection

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 transmitter­ is broadcasting properly. Test the transmit­ter­ with an ALD-800 receiver. This proce­dure­ 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 transmit­ter­. The system is preset at the factory.

Changing the channel can be done quickly by any qualified service techni­cian­. Contact your dealer or the Nady Customer Service Department for details.
