Using Batteries
Precautions when using batteries
o Never use any charger or battery that is damaged in any way.
o Use the battery only for intended purpose.
o No indication of charging: When you start charging a battery that is empty or a battery that has
not been used for a long time, it may take up to 20 minutes before the battery icon appears in
the display.
o If you use the Diorphone near the network’s base station, it uses less power; talk and standby
times are greatly affected by the signal strength on the cellular network and the parameters
set by the network operator.
o Battery charging time depends on the remaining battery charge and the type of battery and
charger used. The battery can be charged and discharged hundreds of times, but it will
gradually wear out. When the operation time (talk time and standby time) is noticeably shorter
than normal, it is time to buy a new battery.
o If left unused, a fully charged battery will discharge itself over time. When charging after
complete discharge, the Diorphone will not display anything for about 30 minutes.
o Use only approved chargers. When a charger is not in use, disconnect it from the power
source. Do not leave the battery connected to a charger for more than a week, since
overcharging may shorten the battery life.
o Extreme temperatures will affect the charging capacity of your battery: it may require cooling
or warming first.
o Do not leave the battery in hot or cold places, such as in a car in summer or winter conditions,
as it will reduce the capacity and lifetime of the battery. Always try to keep the battery at room
temperature. A phone with a hot or cold battery may not work temporarily, even when the
battery is fully charged. Li-ion batteries are particularly affected by temperatures below 0°C
(32°F).
o Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object
(coin, clip or pen) causes a direct connection between the + and – terminals of the battery
(metal strips on the battery), for example, when you carry a spare battery in a pocket or bag.
o Short-circuiting the terminals may damage the battery or the object causing the short-circuit.
o Dispose the used batteries in accordance with local regulations. Always recycle. Do not
dispose of batteries in a fire.
o The only way to turn off the charger is to unplug it, so use an easily accessible AC power
socket.
o
o In case of hot weather or after a prolonged exposure to the sun (e.g., behind a window or a
windscreen), the temperature of your phone's casing might increase, especially when
featuring a metallic finish. Be very careful in this case when picking up your phone and also
avoid using it with an ambient temperature over 40°C or below 5°C.
o Battery information:
o Do not incinerate.
o Do not deform or open the battery.
o Do not allow metal objects (such as keys in your pocket) to short circuit the battery contacts.
o Avoid exposure to excessive heat (>60° C or 140° F), moisture or caustic environments.
