Do not burn or bury them. Use only fresh batteries of the required size and recommended type. Do not mix old and new batteries of different sizes or types. If you do not plan to use the headphones for an extended time, remove the batteries. Batteries can leak chemicals that can damage electronic parts. When the power LED on the headphones turns off, replace your alkaline batteries or charge the rechargeable batteries. When using NiMH rechargeable batteries, capacity of 750mAh or above is recommended. 2 Charge 1. Connect the AC adapter plug into your charging hub’s DC 5.0V jack. 2. Connect the charging hub’s larger plug to your headphones’ jack. Make sure rechargeable batteries are installed and ALK/RCH is set to RCH. 3. Connect the charging hub’s smaller plug to your transmitter’s jack. 4. Connect the AC adapter to a standard power outlet. AUVIO logo on the charging hub flashes blue when charging and lights blue after charging. n Notes: Charge the built-in battery for at least 2 hours before the first time. Music does not play while charging. Charge your transmitter when the AUVIO logo does not light. Recycle your old rechargeable batteries at one of the many collection sites in the U.S. and Canada. To find the site nearest you, visit www.call2recycle.org or call toll-free 1-877-2-RECYCLE.

Slide the battery compartment cover on the left ear cup in the direction of the arrow and open it. 2. Insert two AAA alkaline or NiMH rechargeable batteries (neither included), matching the polarity symbols (+ and –) marked. 3. Use a small tool to switch ALK/RCH to ALK for alkaline or RCH for rechargeable batteries. 4. Replace the cover. w Warning: Never install alkaline batteries with the ALK/RCH switch set to RCH. Alkaline batteries can get hot or explode if you try to recharge them. Power On/Off Turn on/off the headphones. Power LED Lights blue when the headphones are turned on. ON/OFF Turn on/off the transmitter. AUVIO logo lights blue when the transmitter is turned on. AUVIO logo flashes in blue when charging and lights blue after charging. 3 Use your headphones 1. Connect the transmitter to the 3.5mm headphones jack on your audio device. 2. Turn on the transmitter. AUVIO logo lights blue. 3. Turn on the headphones. The power LED lights blue. 4. Set the headphone volume to minimum. 5. Turn on the audio source, and gradually increase the volume to a comfortable level. nNotes: Remove objects between the transmitter and headphones. To preserve battery life, be sure to turn off the headphones and transmitter when you are not using them. Handling and Disposal: Do not burn or bury batteries. Do not puncture or crush. Do not disassemble. Recycle lithium batteries. Do not dispose of in the trash. Never allow loose cells to short circuit against battery tabs or other conductive items. Keep loose cells and battery packs out of reach of children. If the electrolyte in the cells should get on your skin, thoroughly wash with soap and water. If in the eyes, rinse thoroughly with cool water. Immediately seek medical attention. Charging Use only the supplied charging hub for the transmitter built-in lithium battery charging. Be sure the charging hub is powered by the provided AC adapter. Charge batteries on a fireproof surface away from flammable items or liquids. Do not charge inside an automobile, especially while driving. Follow the manufacturer’s instructions for charging the product and do not charge longer than recommended. Unplug the charger when the battery is charged. Listening Safely Set the headphone volume to the lowest setting before listening. After you begin listening, adjust the volume to a comfortable level. Do not listen at extremely high volume levels. Extended high- volume listening can lead to permanent hearing loss. If you connect the transmitter to an audio source headphone jack, set the audio source’s volume to the middle position. Then adjust VOLUME on the headphones to the desired level. Turn off the headphones before turning off the transmitter. This prevents you hearing a loud click that may be generated when you turn off the transmitter.

INTERTEK TESTING SERVICE Report No.: HK09101135-1 FCC ID: AAO330283T RF Exposure Evaluation For Specific Absorption Rate (SAR) evaluation of the Transmitter Unit, with reference to TCB Exclusions List revised on July 17, 2002, portable transmitters with output power less than low threshold and operating within 2.5cm from person’s body can be certified by TCB without the SAR evaluation. The output power for portable transmitters is defined as the higher of the conducted or radiated (EIRP) source- based time averaging output power. And the low threshold is equal to (60/fGHz) mW for d < 2.5cm, where fGHz is mid-band frequency in GHz, and d is the distance from the portable transmitter to a person’s body, excluding hands, wrists, feet, and ankles. For the Transmitter Unit of the tested model of 33-283, the measured peak conducted power was 1.73 mW. The maximum source-based time averaging duty factor is 2.64%. The conducted source-based time averaging output power = (1.73 * 0.0264) mW = 0.046 mW The measured maximum field strength (FS) was 98.3 dBμV/m. The distance (D) between the antenna and the equipment under test (EUT) was 3 meters. From these data, the radiated (EIRP) source-based time-averaging output power can be calculated by: The radiated power = (FS*D)2 / 30 mW = 2.0 mW The radiated (EIRP) source-based time-averaging output power = (2.0 * 0.0264) mW = 0.054 mW The low threshold in the 2400 – 2483.5MHz band is 25 mW. From the above calculation, output power obtained in both method is less than low threshold, it is concluded that the handset can be certified by TCB without the SAR evaluation.
