Radio Shack CT-400 - Manual (Page 9)

• When the battery is not in use, store it un-
charged in a cool and dark place.
• The battery is a sealed unit with no service-
able parts. Do not try to open the case.
• You can purchase additional standard or ex-
tended capacity batteries through your local
RadioShack store.
• A battery can be charged and discharged hun-
dreds of times, but it eventually wears out.
When the operating time (talk time and stand-
by time) is noticeably shorter than normal, it is
time to get a new battery.
• Leaving the battery in a hot or cold place, such
as in a closed car in the summer or winter, re-
duces the battery’s capacity and life. Always
try to keep the battery between 59° and 77°F
(15° and 25°C). A phone with a battery that is
too hot or too cold might not work, even when
the battery is fully charged, until the battery re-
turns to a normal temperature. Nickel metal
hydride (NiMH) batteries are particularly limit-
ed in temperatures below 14°F (–10°C).
• Use the battery only for its intended purpose.
• Never use any charger or battery that is dam-
aged or worn out.
