12 Pulse Laser Station NPL-302 Series Instruction Manual
• To prevent malfunction, keep the charging plug clean.
• If the CHARGE indicator blinks repeatedly after charging starts, there is a
problem with the battery pack. Do not use or charge the battery pack any further,
and contact your dealer.
• If the ambient temperature drops below 0 °C (32 °F) while the battery pack is
charging, the charger stops charging the battery pack. When the ambient
temperature rises above 0 °C (32 °F), charging resumes. Charging will be
completed after restarting.
• If the CHARGE indicator remains lit for more than four hours, and the ambient
temperature during charging was within the specified operational range
(0 °C through 40 °C or 32 °F through 104 °F), there is a problem with the
battery pack. Do not use or charge the battery pack any further, and contact your
dealer.
• During charging or discharging, the battery pack and quick charger will become
warm. This is normal.
• After charging the battery pack, do not recharge it until it has been fully
discharged. Recharging a fully charged battery pack lowers its performance.
• If the battery pack is used at low temperatures (below –20 °C or –4 °F), its
capacity is reduced, and it will allow less operation time than a battery pack
used at normal (room) temperature.
• If a battery pack is not used for a long period, it cannot be charged to its full
capacity again. To improve the battery pack’s capacity, charge and discharge it
several times.
• You can use a battery charger with part number Q-70U/E or Q-70C to charge a
battery pack with part number BC-65. However, these chargers cannot fully
charge this battery pack.
