2 Plug in to the wall outlet.

Charge indicator

High speed charging (50% charge in 10 minutes)	After the charge indicator flashes for approx. 5 – 10 seconds (while checking the remaining amount of power in the battery), it will begin to flash slowly and high speed charging will start*.When the indicator lights steadily (10 minutes later).the rechargeable battery is 50% charged.
Full charge	Leave the battery charger for approx. 20 minutes more until the indicator goes off. (Total charging time: approx. 30 minutes)

- If after flashing rapidly, the indicator lights steadily instead of starting to flash slowly.

This shows that the power in the rechargeable battery still remains. If this happens, charging is performed in the normal speed mode instead of the high speed mode. The charging will be completed when the indicator goes off. The charging time varies according to the remaining amount of power (approx 40 min.).

When you use an optional rechargeable battery

Sony NC-6WM and NC-5WM rechargeable batteries are available.

NC-6WM: The same procedure as the supplied rechargeable battery.

NC-5WM: Set the selector on the battery charger to NC-5WM. You cannot charge the battery at a high speed.

The indicator lights up and the battery will be charged in approx. 40 minutes. (The indicator will go off.)

Notes

• The rechargeable battery may become warm during charging.
- Use only the NC-6WM or NC-5WM rechargeable battery with the supplied battery charger.
- Do not use the battery charger near a receiver. If you do so, it may interfere with the receiver.
- Detach the rechargeable battery from the battery charger when the indicator goes off. Overcharging (for more than 20 hours) may damage the battery.
- Do not short circuit the battery connecting points of the unit when the rechargeable battery is inserted.
- If the rechargeable battery is new or has not been used for a long period of time, it may not be charged completely. (The playing time is shorter.) The battery will be charged fully after it is used several times.
