Many people with active lifestyles like yours have chosen Lexis to improve the quality of their participation in social situations. Lexis is an addition to your behind-the-ear hearing instruments. Simply attaching the small receiver to your hearing instrument creates the mobility and freedom to partici- pate in situations that might otherwise be uncomfortable. You’ll notice improved speech understanding in almost any environment — even in the presence of noise or reverberation, or at a distance from the speaker. Your Lexis solution is compatible with most manufacturers’ hearing instruments, so even if you decide to change your hearing instrument, your investment is safe in Lexis. Lexis conforms to the guidelines of the Mosaic standard. Mosaic (www.mosaic-consortium.org) helps ensure the interoperability of new wireless systems for hearing healthcare. 2163 Lexis User Guide (final) 1/22/03 4:20 PM Page 5 2 1 typical package contents • Lavalier cord • External antenna • Auxilliary input cables • Microphone/ transmitter • Receiver module(s) • Extra color pin locks • Microphone charger • NiMH rechargeable batteries* *NOTE:batteries need to be charged for ? hours before they are ready to use in the microphone/transmitter 2163 Lexis User Guide (final) 1/22/03 4:20 PM Page 6 3 you will also need: • Behind-the-ear hearing aid (contact manufacturer for compatibility information) • Audio shoe: • Must be compatible with your hearing aid •Note:Some versions of Lexis include the audio shoe as a component of the receiver 2163 Lexis User Guide (final) 1/22/03 4:20 PM Page 7 4 2 microphone features (top) On/off/mode switch • • Microphone grille • External antenna jack • Auxilliary audio input jack • Charge jack Superfocus mode • Focus mode • Omni mode • 2163 Lexis User Guide (final) 1/22/03 4:20 PM Page 8 5 microphone features (bottom) • Battery chamber & stand • Channel button • Pocket clip • HI/LO level button • Battery status & channel display 2163 Lexis User Guide (final) 1/22/03 4:21 PM Page 9 6 microphone features (display) • Battery level indicator • Display only shows channel number when in low sensitivity mode • Display alternates between channel number and HIwhen set to boom mic (high sensitivity) level.

Your microphone and receiver must be on the same channel to work together. Never operate two microphones on the same channel — you’ll experience annoy- ing interference. If you are travelling internationally, be aware that your channel may not be approved for use in all countries. Contact your manufac- turer for a list of channels approved around the world. Push button to change channel Microphone and receiver channels must match! 5 changing channels If you want to use your microphone with a receiver on a different channel, you can change the microphone channel as shown here. 2163 Lexis User Guide (final) 1/22/03 4:53 PM Page 12 9 7 changing pin orientation 6 connecting the receiver to your hearing aid Audio shoe required (see 1) Important! Back of Lexis must face same direction as back of hearing aid Note large pin 1 Pull out lock 3 Push in lock 2 Rotate pins to align with audio shoe holes If pins don’t align with holes 2163 Lexis User Guide (final) 1/22/03 4:21 PM Page 13 8 professional fitting Your hearing instrument has unique characteristics. To work properly, your Lexis receiver must be adjusted to match those characteristics. Only a hearing care professional is qualified to perform such adjustments. Fitting procedures are available in the Lexis Fitting Guide. Please visit your hearing care professional for a complete fitting. Lexis has a unique feature in its variable FM gain control that allows your hearing care profes- sional to change the FM signal relationship to the environmental sounds. This creates the optimal signal-to-noise ratio, which improves your ability to hear in noise and over distance. Your hearing instrument has distinctive characteristics, so for it to work properly with your Lexis receiver it must be correctly adjusted. Only a hearing care professional is qualified to perform these adjustments; please visit them for a…

Yes, There is an external and internal antenna. The external antenna gain is 2.5dBi. Used external antenna to test and worst case was measured. 2. Client has been notified to revise user manual. Either Scott, Helen, or I will forward to you when received it from client. See the MPE Calculation Attachment. 3. The Emission Designator: 15K6F3E. Please see the attachement. 4. Yes, 3 orthogonal planes have been investigated and only the worst case reported. -----Original Message----- From: Mike Kuo Sent: Wednesday, February 05, 2003 3:58 PM To: Mike Kuo; CLIENT ADVOCATES Cc: Steve Cheng; Thu Chan; Michael Heckrotte Subject: RE: PHONIC EAR, INC., FCC ID:BRG-871T, AN03T2547 Question #4: Since this device is handheld device, tests shall be performed by positioning the EUT in three orthogonal axes. In the test report, no such procedures were indicated. Please explain.

Test report indicates the ear phone and microphone cable is used as antenna. However, page 23 of user guide indicates that this device is equipped with internal antenna. Through out the test report, there is no indication that which antenna was used during the tests. Please explain. Question #2: User manual does not include RF exposure warning statement. Suggested wording may be " IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, only use supplied antenna that sold with this transmitter. Use of any other antenna which has not been approved by the manufacturer will violate FCC rules and regulation and avoid the user's authority to operate this device. This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter." Question #3: Please provide emission designator and justify necessary bandwidth by using Carson rule. ( 2M+2DK ). Best Regards Mike Kuo The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 60 days of the original e-mail date may result in application dismissal and forfeiture of the filing fee.

Check the calibration of the measurement instrument using either an internal calibrator or a known signal from an external generator. b). Set-up the test equipments as shown. c). Set the level of audio signal generator to obtain 16 dB greater than required for the rated 50% modulation. d). The occupied bandwidth is measured with the spectrum analyzer set at 10 KHz/div scan and 10 dB/div. The transmitter output is connected to the spectrum analyzer. The RBW is set to 1% of the Emission bandwidth. The VBW is set to 3 times the RBW. The sweep time is coupled. MEASUREMENT INSTRUMENT EQUIPMENT MANUFACTURE MODEL NO. CAL.
