Batteries
Taken from "The Land List": The 100, 101, 102, 220, 225, 230, 240, 250, and 340 use one No. 531 (4.5 volt) alkaline battery.
These steps show how to convert to cheaper and more easily found batteries.
The battery compartment for these cameras is on the left side of the back. A little notch towards the top lets you know where to open from.
Basically these models take a really odd looking 4.5v battery with snaps (what you have on typical 9v batteries). Expect to pay $9 plus shipping if you find one.
More than likely the battery is dead, corroded, and probably both. Surprisingly this model didn't have a battery to speak of.
Remove the battery and cut the snaps off. Clean the compartment with some alcohol and swabs.
Remove the screw holding the battery clip.
Look inside and notice there is still an extra contact and black wire; yellow arrow. Remove this by yanking it out.
The real black wire is soldered to a small contact, green arrow, cut it here.
