Powering The Receiver

Install a 9V battery in Battery Compartment

(1), observ­ing­ polarity. To preserve battery life, always turn the ALD-800 receiver off when it is not in use. When the sound becomes weak or distorted, replace the battery. The number of hours of operation per battery is as follows: carbon zinc type battery: 10-12 hours; alkaline battery (recommended): 17-20 hours.

Using the ALD-800 Earphones

Plug the included earphones into the Earphone jack (2) on top of the receiver. The earpads can be ordered sepa­rate­ly,­ and since they cost very little, you may wish to dispose of them after use. However, the earpads can be replaced and reused after being washed in a mild detergent, rinsed and air dried.

Operating the Receiver

While wearing your earphones, stand near the ALD-800 transmitter. Turn the receiver on by rotating the Off/On/Volume wheel (3).

The Power On indicator (4) will go on. (To turn the receiver off, rotate the Off/On/ Volume wheel until it clicks, and the “Power On” indica­tor­ will go out.) Listen for your program source, and adjust receiver volume to a comfort­able­ listening level.

Note: A slight buzzing may be heard if the receiver is used within six feet of the transmit­ter­.

This is normal and does not affect performance. For best performance, keep the receiver and the transmitter at least ten feet apart.

Channel Selection

Your receiver is pre-tuned at the factory to the same channel as your transmit­ter­. Should you wish to have your transmitter channel changed, as explained in the Transmitter Operating Instructions section of this manual, you must also have your receiver(s) retuned as well. Contact the Nady Customer Service Department

for details.

Adjusting Earphones Volume

Listen for your program source, and adjust receiver volume to a comfort­able­ listening level.

Note: A slight hum may be heard if the receiver is used within six feet of the transmitter.

This is normal and does not affect performance.

Testing Receiver Range

Wearing your receiver and earphones, walk around your seating area and listen for audio quality. In certain areas of the room the audio may disappear or “drop out.” This is a normal occurrence whenever radio signals are transmitted inside a building.

If you step away from the “drop out” zone, the audio will return.
