CHARGING THE BATTERY WITH THE INCLUDED AC ADAPTOR 

1.  Charge the built-in Lithium battery a minimum of 5 hours prior to first use. Firmly and securely 

insert the DC plug of the adaptor into the DC Jack on the back of the unit.

2.  Plug the AC Adaptor plug into the 120V AC outlet. Connecting this system to any other power 

source may cause damage to the system.

3.  When the AC power is connected, the battery charging indicator will light solid Red showing 

that the internal battery is being charged. 

4.  After the battery is fully charged, the charging indicator will turn to solid Green.

Notes:  

1.)  Charging time will vary if you are listening to music while charging the internal battery. We 

recommend you place the unit in Power off mode during the charging process or until SB2149 
batteries are fully charged.

2.)  To prolong the life of a rechargeable battery, it is recommended to completely discharge it 

before fully charging it again. 

3.)  Rechargeable batteries need to be cycled for maximum performance and longer battery life. If 

you don’t use the player that often, be sure to recharge the battery at least once a month in 
order to keep the internal battery working properly.

        Battery Note and Care

 

•  Do not burn or bury batteries. 

 

•  Do not puncture or crush. 

 • Do 

not 

disassemble.

 

•  Recycle Lithium batteries. Do not dispose of in the trash.

 

•  Use only chargers rated for Lithium cells. Be sure the charger’s voltage and current 

settings are correct for the battery pack being charged.

 

•  Charge batteries on a fireproof surface away from flammable items or liquids. 

 

• 

Batteries should NEVER be left unattended while charging. Only adults should charge the 
batteries.

 

•  Follow the manufacturer’s instructions for charging the product and do not charge longer 

than recommended. Unplug the charger when the battery is charged or not in use.

NOTE:

 These speakers are not magnetically shielded and may cause color distortion on the

further away from the TV or monitor if unnatural color shifts or image distortion occurs.

tor lights.

panel.

you tune to an FM Stereo station, the FM STEREO LED Indicator will light.

4.  Adjust the MASTER VOLUME knob to obtain the desired sound level.

FM & FM-STEREO RECEPTION

● 

Set the BAND SELECTOR to “FM” position. Stations will now be received in MONO mode. 

When a FM station is weak or distorted, listening is usually improved by switching the band 
selector to the FM (mono) position.

● 

Set the band selector to “FM-ST” position to receive stereo broadcasts. The FM-Stereo LED 

indicator will light up to show a FM stereo station is detected.
