Battery Information 
 
 
In order to get the best performance of your DP730/DP722 Handsets, we recommend using original 
batteries provided in the package or batteries compliant with above specifications. The specifications 
may differ depending on the age and capacity of the batteries used.  
Important Note: Be careful when inserting the batteries into your handset to avoid any risk of short-
circuit, which lead to damage your batteries and/or the handset itself. Do not use damaged batteries 
which can increase the risk of serious harm.
