Insert three AAA alkaline or rechargeable batteries (neither included), matching the polarity symbols (+ and –) marked inside. 2. Switch ALK/RCH to ALK for alkaline or RCH for rechargeable batteries. 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. Battery Notes: Dispose of old batteries promptly and properly. 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 blinks, replace your alkaline batteries or charge the rechargeable batteries.

Press 1to turn on the transmitter. The power LED lights red. 2. Slide Power On/Off to On to turn on the headphones. The power LED lights blue. 3. Set the headphone volume to minimum. 4. Turn on the audio source, and gradually increase the volume to a comfortable level. nNote: Place your transmitter away from strong light; avoid pointing it at a window where sunlight might prevent optimum reception. Remove objects between the transmitter and headphones. To preserve battery life, be sure to turn off the headphones when you are not using them. wCAUTION: Do not connect the transmitter to a speaker output. Doing so could damage the transmitter or the audio source. 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.

Analysis Report Report No.: 13031420HKG-001 The Equipment Under Test (EUT) is a 900MHz stereo wireless transmitter for it corresponding headphone and using two discrete (left and right channel) radio carriers rather than the conventional FM multiplex system. Transmit carriers are generated by two VCO and controlled by a microprocessor. The operating frequencies are 911.400MHz and 915.600MHz for Left and Right channel respectively. It is powered by an AC/DC adaptor (Model: U120025D, Input: 120VAC, Output: 12VDC, 250mA). The unit can be activated at the back of the unit. At the same time the power on LED (red colour) in front of the unit will be lighted. Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength: 88.9dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 91.9dBμV/m at 3m in frequency 2.4GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.465mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.465mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (0.9156) mW = 15.68 mW Since the above conducted output power is well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
