BATTERIES  
Charge the Handset Battery Pack  
This battery should remain charged up to six days with the ringer  
turned on and up to 10 days with the ringer off. A fully charged  
battery provides an average talk time of about 10 hours.  
The battery pack needs charging when:  
— A new battery is installed in the handset.  
— The phone beeps twice every five seconds.  
— The screen displays  
and the low battery icon.  
Place the handset in the base so the CHARGING light turns on.  
The battery pack is typically fully charged in 10 hours.  
You can keep the battery fully charged by returning the handset  
to the base after each use.  
If you repeatedly get a low battery indicator, even after charging  
overnight,the battery should be replaced. Use only Replacement  
Battery 3301,SKU#91076.  
CAUTION: To reduce the risk of fire or injury to persons or  
damage to the telephone, read and follow these instructions  
carefully:  
Charge the battery provided with or identified for use with this product  
only in accordance with the instructions and limitations specified in the  
User’s Manual, Part 1.
