122 Safety Precautions and Conditions of Use
• When the battery charging alert is displayed on the screen,
charge the battery as soon as possible. If you continue using
your phone ignoring the alert, the phone may cease to function,
and all data and settings you have stored may be lost at any
moment.
• Before removing the battery from the phone, make sure the phone
is switched off.
• Replace and charge the new battery as soon as possible after
removing the old one.
• Do not touch the battery terminals. Batteries can cause damage,
injury or burns if a conductive material touches exposed terminals.
When the battery is detached from the phone, use a cover made
of non-conductive material for keeping and carrying the battery
safely.
• Recommended temperature for using and storing batteries is
approximately 20°C.
• The batteries’ performance is limited in low temperatures,
particularly below 0°C and the phone may not work temporarily
regardless of the amount of remaining battery power.
• Exposing the phone to extreme temperatures will shorten battery
life.
• The battery can be charged and discharged hundreds of times but
it will eventually wear out. When the operating time (talk-time and
standby time) is noticeably shorter than normal, it is time to buy a
new battery.
