Safety Information
HEARING SAFETY:
CAUTION!
The R863 receiver is designed to amplify sounds to a high volume level
which could potentially cause hearing damage if used improperly.
To protect your hearing and the hearing of others:
1. Make sure the volume is turned down on the receiver before putting
on the earphone or headphone. Then adjust the volume to a
comfortable level.
2. Set the volume level at the minimum setting that you need to hear.
3. If you experience feedback (a squealing or howling sound), reduce the
volume setting and move away from the microphone being used with
the T800 transmitter.
4. Do not allow children or other unauthorized persons access to the
receiver.

The R863 receiver may be supplied with Alkaline batteries. Do not attempt
to recharge Alkaline batteries, which may explode, release dangerous
chemicals, cause burns, or other serious harm to the user or product. See

device, consult your physician or the manufacturer of your pacemaker
or other medical device.
