- 75 -Usage cautions and notes● Do not peel off or scratch the battery covering.• Do not use commercially available batteries that are entirely or partly uncovered. Donot use batteries with flat poles. Using such batteries may cause leakage, heatgeneration or explosion.● Take spare batteries when going out.• Be aware that the recording time is reduced in low temperature conditions such as ata ski slope. Battery performance deteriorates when the ambient temperature is low(10 °C (50 °F) or less) and the recording/playback time may become extremely short.In particular, when using alkaline batteries, warm them in your pocket etc. beforeusing them. Make sure that pocket heaters or metal objects such as lighters do notcome into contact with the batteries when warming them in your pocket etc. Thebattery performance will recover when the temperature returns to normal.• Battery performance may vary greatly depending on the brand used, the storage lifefrom the date of manufacture, and the storage conditions of the batteries.• Depending on the temperature and the conditions of use, the camera may notoperate properly or the batteries may run out (the remaining battery power may notbe accurately displayed). This is not a malfunction.• Expended batteries may temporarily recover some performance if they are left fora period of time. However, they cannot be used for an extended period. Be sure toreplace them with new batteries.Rechargeable Ni-MH batteries● You can use Ni-MH batteries after charging them with a dedicated battery charger.However, improper handling of the batteries may cause leakage, heat generation, fireor an explosion. Observe the following.• If there is dirt on the battery poles, you may not be able to charge the batteriesnormally. Carefully clean the battery poles and battery charger terminals with a softdry cloth.• Do not peel off or scratch the covering on Ni-MH batteries.• When the batteries are used for the first time, or after having not been used for a longperiod of time, they may not fully charge. This is a characteristic of Ni-MH batteriesand is not a malfunction. Battery performance will return to normal after a fewcharges and discharges.• We recommend charging the batteries after they are fully discharged. If you repeatcharging before they are fully discharged, battery performance may be reduced. (Thisis called “memory effect.”)If a “memory effect” occurs, continue using the batteries until the camera can nolonger perform recording or playback and then charge them fully. Battery performancewill be restored after a few charges and discharges.• Once the Ni-MH batteries have reached full charge, do not continue to charge them.• Over time, Ni-MH batteries naturally discharge and their performance lowers even ifthey are not used. If the batteries are left in the camera in this condition, they will bedrained excessively and may become unusable even if they are charged again.• When storing the batteries for a long period of time, we recommend charging themonce a year. Remove the batteries from the camera and store them again after theyhave been completely expended.
