Note: 
•  Actual battery performance depends on usage and 
ambient environment. 
•  Even after the batteries are fully charged, the 
handset can be left on the base unit or charger 
without any ill effect on the batteries. 
•  The battery level may not be displayed correctly 
after you replace the batteries. In this case, place 
the handset on the base unit or charger and let it 
charge for at least 7 hours. 
Intelligent eco mode 
This feature automatically reduces handset power 
consumption by suppressing handset transmission 
power when the handset is close to the base unit. 
•  When this feature is activated, ECO is displayed. 
However, during a cellular call, ECO is not 
displayed even though this feature is activated. 
•  Eco mode is turned off when the clarity booster is 
activated (page 80).
