Sears KS-2 - Manual (Page 9)

Batteries for the KS-2 [NOTE: click here for a listing of most Chinon
Camera Batteries]
Two LR-44 Alkaline batteries; life-span about 6 months; or two SR-44
Silver Oxide batteries; life-span about 12 months.
* Since dirt or sweat on the batteries may cause a bad contact, wipe
the batteries clean with a dry cloth before inserting them.
* When your camera is not used for a long period of time, remove the
batteries.
* Generally. in cold conditions, the voltage of the batteries
decreases. and this will impair the functioning of the shutter
and exposure meter. In these cases, either warm up the batteries
or keep a spare set of batteries warm in your pocket ready to
insert just before shooting.
* If no batteries are inserted, if they are incorrectly inserted,
or if they are worn out, the camera will not operate. Check that
the batteries are correctly inserted, and if they are and the
camera does not operate, replace them with new batteries.
* When the voltage of the batteries is getting low, the BAT
(Battery Low Warning Signal) in the Viewfinder will blink on and
off.
Please change the batteries without delay.
