Replacing Batteries
Turn the camera off and make sure that the power-on lamp has gone out before
removing or inserting batteries.
Read Battery Warnings
Read and follow all warnings and instructions supplied by the battery manu-
facturer.
Damaged Batteries
The following batteries can not be used:
• Batteries with peeling or damaged insulation. Using
batteries with damaged insulation could result in
leakage, overheating, or rupture. Note that due to
manufacturing defects even new batteries may have
faulty insulation.
• Batteries with insulation that covers only the sides
of the battery and not the area around the negative
terminal.
• Batteries with a fl at negative terminal. Do not use
such batteries even if the insulation adequately covers
the area around the negative terminal.
EN-MH1 Batteries
Using an MH-70 battery charger, charge EN-MH1 batteries before fi rst use. Charge
each pair of batteries at the same time — do not charge batteries one at a time or mix
batteries with different charges. Note that EN-MH1 batteries may discharge quickly
immediately after purchase or after the batteries have been left unused for an extend-
ed period. This is normal, and the batteries will retain a charge for longer periods after
being used and recharged several times. For more information on charging batteries,
see the documentation provided with the MH-70.
Alternative Power Sources
• To power the camera continuously for extended periods, use an EH-61 AC adapter
( 81). Do not, under any circumstances, use another make or model of AC
adapter. Failure to observe this precaution could result in overheating or in damage
to the camera.
• We recommend that you buy CRV3 lithium batteries as a back-up power source.
• The camera can also be used with a pair of ZR6 (AA) nickel-manganese batteries or
FR6/L91 (AA) lithium batteries.
