This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device

does not cause harmful interference.

This device complies with INDUSTRY CANADA R.S.S. 210, en conformité avec IC: RSS-210/CNR210.

Operation is subject to the following conditions: 1) This device may not cause harmful interference and 2)

this device must accept any interference received, including interference which may cause undesired

operation.

CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing to qualified service

personnel. No user-serviceable parts inside. Do not expose to rain or moisture.

The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and

compliance with federal regulations. Do not attempt to open the receiver or transmitter. To do so will void the

warranty, and may cause improper operation.

Notice to individuals with implanted cardiac pacemakers or AICD 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.

200 Series Owners Manual v.1 7-6-06 Page 7 of 9 Tips To Obtain the Best Results 1. Use only fresh alkaline batteries. Do not use “general purpose” (carbon-zinc) batteries. 2. Position the receiver so that it has the fewest possible obstructions between it and the normal location of the transmitter. Line-of-sight is best. 3. The transmitter and the receiver should be as close together as conveniently possible, but not less than 6' (2 m). 4.
