Using the Optional MS-D70 CR2 Lithium Battery Holder When inserted in the MS-D70 battery holder (available separately), CR2 lithium batteries can be used as a backup power source in place of the EN-EL3a. CR2 batteries are however suited to use at a restricted range of temperatures. Read the following notice before using CR2 batteries. Using CR2 Lithium Batteries Note the following when using CR2 lithium batteries: The capacity of CR2 batteries drops sharply when the ambient temperature is below 20 °C (68°F). Operation has been confirmed with the following CR2 lithium batteries: SANYO CR2 lithium batteries Toshiba CR2 lithium batteries Maxell CR2 lithium batteries Energizer CR2 lithium batteries The capacity of the above batteries may vary with storage conditions; in some cases, they may cease to function before their expiry date. The presence of fingerprints or other foreign matter on the battery terminals or on the battery contacts inside the holder can also affect battery performance; clean the terminals and contacts with a dry cloth before use. Place three CR2 batteries in the MS-D70 battery holder as shown in the illustration on the holder and insert the holder in the battery chamber as described on the previous page. CR2 batteries can not be recharged. 15
