55 Charging and caring for batteries
■
Before using a Li-ion battery, read the Li-ion Bat-
tery Safety Information (MPC-00006-xx) included
with your battery, and follow the instructions it pro-
vides. Incorrect use of a Li-ion battery can cause
explosion or fire.
■
Do not short-circuit the battery contacts, neither
intentionally nor accidentally, e.g. by placing the
battery with conductive materials such as keys or
jewelry inside a pocket or container. Short-circuit-
ing the battery contacts can heat up the conduc-
tive material.
■
Do not obstruct the vent hole(s) on the battery.
If the vent on the battery is obstructed the battery
may explode, causing personal injury and/or
equipment damage. If the vent on the radio is
obstructed, audio quality and/or key function may
deteriorate and radio seals may be damaged.
Notice
Turn the radio off before removing the battery,
and turn it on again after attaching the battery. This
ensures that the radio powers down and up correctly.
Failing to follow this procedure may require the radio
to be turned off then on again to operate correctly.
Charging temperatures
Notice
Do not expose a battery to very high or very
low temperatures for extended periods of time. Doing
so will shorten the usable life (‘service life’) of the
battery.
To achieve the best results when charging your
battery:
■
Before you begin to charge your
battery, make sure that the battery
temperature is close to the room
temperature in which the battery is
to be charged.
■
If possible, charge the battery in
temperatures between 50 °F
and 77 °F (between 10 °C and 25 °C).
