IMPORTANT SAFETY INSTRUCTIONS:

CAUTION! TO REDUCE THE RISK OF DAMAGE, SAVE THESE INSTRUCTIONS

- Do not store, place, or use the charger where it may come into contact with excess heat, water or moisture.

• High-voltage internal components present the risk of electric shock when exposed.

- Charge only on a vibration-free, dry surface at room temperature.

- Should you ever notice smoke or a strange odor coming out of the charger, immediately unplug the charger from the power outlet. Using the charger under these conditions can cause fire and electric shock.

- Do not short-circuit the terminals of your battery or charger.

- Do not attempt to disassemble any part of the charger.

- Use this charger with the specified types of batteries only.

- The charger, adapters, and batteries may feel warm during the charging process. This is normal.

- Unplug the charger from the power outlet and clean the area around the prongs of the plug when necessary. The presence of dust around the prongs can cause fire.

- Never use an electrical outlet whose voltage is outside the rating marked on the charger. Doing so can cause fire or electric shock. Use only the supplied AC adapter or DC car cord (optional) for the charger.

• To reduce the risk of electric shock, unplug the charger from the outlet before attempting cleaning or when not in use.

- Do not use solvents to clean the unit. They may damage the surface and the plastic parts of the unit. Clean the unit gently with a soft dry cloth only.

• Not recommended for use by children.

TO MAXIMIZE BATTERY PERFORMANCE

• Make sure the battery is fully charged before use.

- Clean the battery and terminals with a clean, soft, dry cloth.

- The battery may be warm during use or recharging. This is normal.

- When storing the battery for an extended period, be sure that it is not completely charged, nor completely discharged. The ideal level is a 40% charge. This is approximate; the closer the battery is to this level, the better it will hold its charge during storage. The battery should be stored in a cool, dry place. The recommended temperature for storage is 59°F (15°C). You may store a battery in a refrigerator. Do not store batteries in a freezer.

- Remove the battery from your equipment when not in use. Some electronic equipment will draw current even when the switch is off.

- When operation time has noticeably shortened, the battery may need to be replaced.
