On charging the battery pack

• Charge the battery pack before using this unit.
• We recommend charging the battery pack in an ambient temperature of between 10°C to 30°C (50°F to 86°F) until the POWER/CHG (Charge) lamp turns off. The battery pack may not be effectively charged in temperatures outside this range.
• The POWER/CHG (Charge) lamp may blink during charging this unit in the following situations:
  • Battery pack is damaged.
  • The temperature of this unit is low. Put it in a warm place.
  • The temperature of this unit is high. Put it in a cool place.

Effective use of the battery pack

• Battery pack performance decreases at a low ambient temperature lower than 10°C (50°F). In cold places, therefore, the operational time of the battery pack is shorter.

Remaining battery charge

• If the battery pack runs out quickly even though the remaining charge indicator is high, fully charge this unit again. The remaining charge indicator will then be displayed correctly. Note that it may not be displayed correctly in the following situations:
  • This unit is used for a long time at high ambient temperature.
  • This unit is left fully charged.
  • This unit is used heavily.

On battery pack life

• The battery pack has a limited life. Battery capacity decreases over time and through repeated use. If decreased usage time between charges becomes significant, it is probably time to replace it with a new one.
• The battery pack life varies according to how the battery pack is used.
