CHARGING THE HEADPHONES Battery type: Rechargeable batteries AAA No. of cells: 2pcs Rated capacity: 300 mAH / 9 hrs Rated DC output voltage (V): 2.4V Rated DC output current (A): 60mA Step 1: Insert 2 pcs AAA size rechargeable batteries into the Battery Compartment (8) at the Left hand side of the headphones. Step 2: Switch OFF (3) the headphones. Step 3: Connect the transmitter to a conveniently located electric wall outlet with the supplied AC/DC Adaptor (18). Step 4: Insert one end of the Charging Cord (19) to the Charging Socket (14) at the rear side of transmitter and the other end to the Charging Socket (7) of headphones. The batteries should be charged for a full 12 hours before use. During charging process, the Charging LED Indicator (10) will glow RED showing the headphone is being charged. *** Regular (non-rechargeable type) batteries can also be used to operate this headphone. However, you must never attempt to charge non-rechargeable batteries in this appliance as this could prove dangerous. Step 5: When the batteries have been charged, remember to remove the Charging Cord from the headphones. 6 *** Charging procedure should never exceed 48 hours. Caution! To avoid risk of fire or injury, do not attempt to recharge non-rechargeable batteries. Replace only with the same or equivalent type recommended by the manufacturer. Please dispose of old, defective batteries in an environmentally friendly manner in accordance with the relevant legislation. TROUBLE SHOOTING GUIDE If you encounter any trouble in setting up the Headphones, please check the following points: (1) Distorted sound quality or unclear sound: ~ Check if the sound of your audio source is distorted and whether the volume control is tuned to the suitable level. ~ Check if the batteries in the headphones have insufficient power. Replace fresh ones if necessary. ~ Check if you have selected the best channel, Turn the Channel Tuning Knob (4) again to check. ~ Check if the distance between the headphones and transmitter are within the effective range. (The effective range of the device is approx. 100M in open area.) Place the headphones closer to the transmitter. (2) No Sound from the headphones: ~ Make sure that your audio equipment, the transmitter and headphones are properly connected, powered and switched ON. ~ Check if the batteries are inserted properly into the battery compartment. ~ Check if the transmitter is powered on with the AC/DC adaptor: the Power LED Indicator (11) will glow GREEN showing the transmitter is powered (only when there is audio signal from the audio source). ~ Check if all the connection cords are properly connected. (3) Mono Sound: ~ Check if the audio source is mono only, use stereo audio source. (4) Interference: ~ At the rear side of the transmitter, there is a Channel CH1/CH2/CH3 Switch (12), select a different ch…
