This device complies with the European R&TTE directive 1999/05/EC.

Operation is subject to the condition that this device does not cause harmful interference.

Notice to individuals with implanted cardiac pacemakers orAICD devices:

Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difficulty, especially if they are at least a few inches away. However, since a ”body-pack” mic transmitter typically is placed against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent to the medical device. Note also that any medical-device disruption will cease when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any problems with the use of this or any other RF equipment.

CAUTION! The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compliance with national regulations. Do not attempt to open the receiver or transmitter. To do so will void the warranty, and may cause improper operation.

Warning: To prevent fire or shock hazard, do not expose this appliance to rain or moisture.
