INTRODUCTION
Please read and follow the instruction manual 
carefully before operating in order to avoid any 
damages to the unit. Any adjustment or repair 
should be done by a qualified service center only 
to receive warranty.
BATTERY OPERATION 
 (BATTERIES NOT INCLUDED)
Your unit operates on two(2) AA size alkaline batteries. 
Open the CD cover and insert the batteries in the battery 
compartment following the polarity diagram located 
inside.
RE-CHARGEABLE BATTERY OPERATION
(RE-CHARGEABLE BATTERIES NOT INCLUDED)
You can operate this unit with two “AA” rechargeable 
batteries. For new or exhausted rechargeable batteries, 
we recommend that (Refer to battery manufacturer’s 
guide).
 When operating the unit with AC adapter 
 and non-rechargeable batteries in the 
 compartment, please make sure to set the 
“Charge” switch to “Off” position to avoid 
 damaging the unit.
1. Open the CD cover and insert the batteries (2*”AA”) in 
  the battery compartment following the polarity diagram 
  located inside.
BOTH BATTERIES MUST BE RECHARGEABLE NiCd 
TYPES OTHER BATTERIES MAY EXPLODE OR LEAK.
2. Plug in AC adapter and slide the “CHARGE SWITCH“ 
  to “ON” position to start charging.
3. Unplug the AC adapter after charging.
DO NOT CHARGE THE BATTERIES MORE THAN 24 
HOURS OR MORE THAN RECOMMENDED TIME. 
OVERCHARGING MAY DETERIORATE THE PERFORMANCE OF THE RECHARGEABLE BATTERIES.
4. If the operating time decrease drastically after the 
batteries have been recharged properly, purchase new 
rechargeable NiCd batteries. 
Do not attempt to recharge alkaline batteries. This may 
cause leakage and damage to the unit. 
Do not mix alkaline batteries with rechargeable batteries.
MONEY SAVING TIPS.
Due to the nature of CD technology, the unit uses power 
even when the unit is off. To extend the batteries’ life, use 
the adapter for indoor operation or where power is 
supplied. Use the battery operation only when the unit is in 
mobile.
DBBS FUNCTION
The Dynamic Bass Boost System(DBBS) enhances the 
low frequency(Bass) response of the output. Set the
Volume to low listening level and press DBBS switch in 
the direction of the arrow to turn this function ON.
Note: Some CD’s with DBBS may exceed the bass 
response capacity and can cause distortion. Do not play 
DBBS in high volume. Playing DBBS in high volume may 
cause damage to the headphone and more importantly to 
your hearing.
HOLD FUNCTION
This HOLD function prevents any unwanted function 
changes during PLAY or STOP mode. Slide HOLD switch 
to the arrow direction (or opposite) to turn the function 
ON (OFF). No other function buttons operate on HOLD 
mode, except DBBS function.
CAUTION
Hearing experts advise against the constant use of 
personal stereos played at high volume. Constant high 
volume use can lead to hearing loss. If you experience 
ringing in the ears or hearing loss, discontinue use and 
seek medical advice.
To remove the disc from its storage case, press down on 
the center of the case and lift the disc out. Hold it carefully 
by the edges as shown below.
Insert the disc into the unit with the label of the disc 
facing up. 
Gently wipe the disc using a soft cloth from the center 
to the outer direction to remove dust, fingerprints or any 
other particles on the disc surface.  Never use 
chemicals, such as record sprays, anti-static sprays, 
benzene or thinners to clean the CD. These chemicals 
can damage the disc surface permanently. 
To avoid serious scratches on CD, keep them in the 
cases after each use. Scratches can cause the laser 
pick-up skip in the future play. 
Do not place stickers or write anything on the disc.
Read the instruction manual before operating this unit. 
Do not expose the unit to high temperature or humidity. 
Use dampened soft cloth to clean the unit. Do not use 
strong detergent or solvent to clean the unit.
Ensure that all electrical connections(including the main 
plug, extension leads and interconnections between 
pieces of equipment) are properly made and in 
accordance with the manufacture’s instructions. 
Consult your dealer if you are ever in doubt about the 
installation, operation or safety of your equipment.
IMPORTANT
The CD mechanism and the sensitive circuitry may 
cause interference to a radio tuner nearby. Do not 
operate this unit while operating other radio devices.

        radiation. Avoid direct exposure 
        to the beam.
