Using batter-ies with damaged insulation could result in leakage, over-heating, or rupture. Note that due to manufacturingdefects even new batteries may have faulty insulation.• Batteries with insulation that covers only the sides of thebattery and not the area around the negative terminal.• Batteries with a flat negative terminal. Do not use such bat-teries even if the insulation adequately covers the areaaround the negative terminal.Alkaline BatteriesPerformance of alkaline batteries may vary greatly depending on the manufacturer. Choose a reli-able brand.EN-MH1 BatteriesUsing an MH-71 battery charger, charge EN-MH1 batteries before first use. Charge each pair ofbatteries at the same time — do not charge batteries one at a time or mix batteries with differentcharges. Note that EN-MH1 batteries may discharge quickly immediately after purchase or after thebatteries have been left unused for an extended period. This is normal, and the batteries will retaina charge for longer periods after being used and recharged several times. For more information oncharging batteries, see the documentation provided with the MH-71.Alternative Power SourcesTo power the camera continuously for extended periods, use an EH-62B AC adapter (Q 113).
