MEMO
• New CR2 batteries were used under Pentax testing conditions.
• Actual battery life and performance may vary drastically depending on
usage of autofocus, built-in flash and external conditions such as
temperature and freshness of the batteries.
• Generally battery performance is temporarily deteriorated as
temperature decreases. When the camera is used in a cold
environment, keep this product warm by holding it in some protection
against cold. Battery performance once deteriorated due to low
temperature will be recovered when the batteries are returned to room
temperature.
• See page 128 regarding battery life when "Battery Grip BG-20" is used.
