 Although the battery pack’s operating temperature range is from 0 °C to 40 °C (32 °F
to 104 °F), the optimal range is from 10 °C to 30 °C (50 °F to 86 °F). At cold
temperatures, performance will temporarily decline. Warm it in your pocket before use.
 Replace the battery pack if the usable time after full charge diminishes substantially at
normal temperatures.
About the battery terminal cover
The battery terminal cover has a [ ]-shaped hole. This is useful when you wish to
differentiate between charged and uncharged battery packs. For example, with charged
battery packs, attach the terminal cover so that the [
]-shaped hole shows the white
label.
Mini DVD Disc
 Keep the disc clean of dust, dirt or smudges. If it gets dirty use a dry, soft lens-cleaning
cloth to remove any fingerprints, dirt buildup or smudges from the disc surface. Clean
the disc in a radial motion from its center outwards.
 Never use a chemically treated cloth or flammable solvents such as paint thinner to
clean the disc.
 Do not bend, scratch or wet the disc and do not subject it to strong shocks.
 Do not attach labels or stickers on the disc surfaces. The disc may not rotate in a stable
manner and this may cause malfunctions.
 Return discs to their case for storage.
 When writing on the label side of the disc, avoid hard tip pens. Use waterproof soft-
tipped felt pens instead.
 Moving a disc rapidly between hot and cold temperatures may cause condensation to
form on its surfaces. If condensation forms on the disc, put it aside until the water
droplets have evaporated completely.
 Never expose the disc to direct sunlight and do not store it in places subject to high
temperatures or high humidity.
 Make sure to finalize a DVD-RW disc recorded in VIDEO mode before inserting it in a
DVD player, DVD recorder or a computer’s DVD drive. Failing to do so can result in the
loss of the recorded data.
