Battery & Charger
Getting Started
Before using your handset for the first time, charge the battery.
Battery Pack
7 The battery pack of your handset uses a lithium ion battery. It has a
tendency to gradually lose its voltage with the operating time as shown in
the figure below.
7 Extreme temperatures will reduce battery capacity and shorten the
operating time. Do not use the battery pack in high temperatures. This may
shorten battery life.
7 Charging at low temperatures does not produce the best results. Make
sure you charge the battery pack at temperatures of 5 to 35 degrees.
7 When storing the battery pack separately, make sure you put it in a case,
etc. and store it in a dry and cool place. This will avoid short-circuiting the
battery pack terminal. It is recommended that you store it uncharged.
7 Repeated charging and discharging of a battery shortens the operating
time.
