TU-10 is a tube headphone amplifier, the sound feels warmer than transistor products. it has built-in battery protection circuit. It powers off after is is fully charged automatically, Can realize the use of human intelligence.

Direction for use:
- CD/MP/MD:connect the LINE OUT/PHONE OUT signals to TU-10 INPUT socket by RCA to 3.5 audio cable.
- Switch & volume control share the same knob:Please rotate the VOL Knob to the left,then plug in your Headset/earplugs to HEADPHONE socket.
- Turn on your media player, and tune VOL knob from left to right till the volume is suitable.
- Turn off: When you do not want to listen, please take off the headphone,turn down the volune till the machine is powered off.

Buyer's Notes:
- Please charge it only when it's power off. Or it will affect the Charge balancing of the 2 Lithium battery so that you might be unable to charge it.
Please pulled out the power supply while using it!
- Storage: Please keep it  fully charged before storage if you do not use it for a long period. Be sure to charge it every 3-6months,Empty electricity stored isforbidden!
- If it is ran out of electrisity, the volume will become smaller, please charge it in time.
It's better to avoid charging it till it's completely ran out of electrisity!
