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 SB2145 
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.
