BATTERY INFORMATION
New Batteries
A battery that is delivered with the phone is not charged.
However, there may be enough power to turn the phone on.
Before using the phone, it is recommended that you
condition the battery by first charging it, and then
discharging it, three times in succession. See chapter 3.
Batteries and Recharging for information about battery
conditioning.
Used Batteries
An old battery that no longer works MUST be returned
to the place of purchase or to a place where used
batteries are taken care of for recovery. It must NOT be
disposed of together with household waste.
