Insert 2 pieces of AAA size rechargeable batteries (supplied in the package) into the right earphone's battery compartment (supplied in the package). Make sure the batteries are placed at the right polarity. 3. Snap the earpad mounting back to the earphone cabinet after inserted the batteries. OPERATION TRANSMITTER Turn on the audio source (TV or audio component) to which the transmitter is connected with. The Power / Signal LED on the transmitter will start light on in red when it receives the audio signal. HEADPHONE RECEIVER 1. Turn on the headphone by pressing the Power button. The POWER LED (Red) will light up, the green LED will be flashing until signal link between transmitter and receiver is established. 2. Place the headphone on your head and adjust for comfort. To obtain the desired sound level, you can adjust the volume control on the headphone. 3. If interference or poor signal reception occurs, the headphone will perform the muting function automatically, and the green LED will be flashing and search for the best channel. 4. Charging the batteries a) Turn OFF the headphone first. b) Retract the cabinet hanger back to the Headband. c) Place the headphone on the transmitter's charging cradle. The charging process begins automatically, and the charging LED will light up in green when the charging contacts of transmitter and headphone are made successfully. When the charging process is completed, the charging LED will off d) For the initial use, please charge the battery for 7 hours. e) If the headphone is not in use, please place it back to the transmitter's charging cradle. IMPORTANT 1. Switching Off a) For protection of the transmitter and power saving, the transmitter will be off automatically if there is no audio source signal for around 4 minutes. If the audio source signal returns, the transmitter will automatically switches back on. Then, power on the headphone again b) The headphone will switch off automatically if there is no signal from the transmitter 2. Make sure the headphone is turned off when charging is in process 3. Only use the included rechargeable AAA batteries. When the headphone is not in use, turn the headphone OFF. 4. To ensure a long service life, fully charge the batteries before using the headphone for the first time. Ensure the charging socket located on the right earphone connects securely with the charge prongs on the transmitter cradle. Depends on the capacity of the rechargeable battery to be used, the battery charging process will be around 5 to 7 hours. This device must be used with the AC/DC adaptor supplied in the package. TROUBLE SHOOTING No Sound - Ensure the AC/DC adaptor is fully inserted into the AC outlet and the power connection input on the transmitter. - Ensure the headphone is switch ON. - Headphone battery charge level may be too low, recharge the batteries fully. - Ensure the TV or the connected audio device is switched ON. - The volume of headphone may be too low, adjust the volume to a moderate level. - The audio signal input level is too low. Increase the volume of the audio source. Distortion - Ensure the volume level of headphone is set to an approximate level. - The headphone is too far from the transmitter, move it closer. - The audio signal input level is too low. Increase the volume of the audio source.

MPE Calculation (Mobile Device) FCC ID: MVADHP381A-001T EUT Description: 2.4GHz Digital Wireless Headphone (transmitter=docking part) Company: Uni-Art Precise Products Ltd Model: DHP380A Typical use distance: d β₯ 20 cm Frequency: 2406-2472MHz (31 channels) Modulation: FHSS(GFSK) Power density limit for mobile devices at 2.4GHz: S β€ 1 mW/cm 2 Maximum measured conducted power (Peak): P conducted = 14.55 mW = 11.63 dBm Antenna Gain: G = 2 dBi Remark: Average β€ Peak, which means that calculating the power density applying Peak power is worst case. Calculation: P radiated = P conducted + G linear = 11.63 dBm + 2 dBi = 13.63 dBm = 23.07 mW (P radiated ) S = ----------- (mW/cm 2 ) = 0.0046 mW/cm 2 (4Ο x d 2 ) Conclusion: At 20 cm distance, the power density EUT appears to be (far) below the required limit, so PASS.
