When using rechargeable batteries and a charger, use only the combination of rechargeable batteries and charger speci ed by the battery manufacturer.
• When turning the unit upside-down, get a bunch of newspapers or magazines, and place them under the four corners or at both ends to prevent damage to the
buttons and controls. Also, you should try to orient the unit so no buttons or controls get damaged.
