Abstract
A battery powered camera with a collapsible handgrip movable between a closed and an extended position is equipped with a battery checker that signals when the battery drops in capacity to a predetermined level. The battery checker is operable only during the period in which the handgrip is moved between the closed and extended position or vice versa. The battery powered camera further comprises means for signalling a switching state in which the main power switch remains closed. The signalling means is also operable only when the handgrip is being moved between closed and extended positions.
