The manual recommends Alkaline 1.5v or Manganese batteries. It also says NOT to use Nickel Cadmium at 1.2v
NiMh rechargeable batteries are also 1.2v .The camera may not function with the lower voltage.
The two batteries run the Photocell/Light Meter, Film Advance & Flash.
The camera may have circuitry that requires the 1.5 volts type batteries.
Good luck, I hope you get it going.
Throw a couple of rechargeable batteries in & see what happens. The manual also says Manganese batteries. I've never heard of these or can find any data on them.
Good on'ya Mike. That's what we wanna see. Initiative!
Knowing the photography buff's back at Ricoh HQ in 1981 & a bit, would of said........
:?: "What about someone that can't get Alkaline batteries & only has - say Ni-CD's?"
Another guy in a white coat says " We will future proof it & put a sticker in the battery cover!
1st guy in white coat, "But we have already printed the manuals!"
2nd guy in white coat, "And tweak some electronics so it will work, even when proper batteries run flat.The thing will keep running"
Or something to that effect. I don't know any of the guy's at Ricoh. All I know is that they build & shoot with the same stuff as you.
& I.
Bung some film in the little bugger & real of some shots Mike.
It's not rocket surgery; It's photography.
Most compact cameras of that era weren't designed to use rechargeables (I think because of higher current, not lower voltage) so many of them may have been marked "Ni-CD or Ni-Mh" and additionally "DO NOT USE" or other sign warranting not to use them. btw manual also states not use use rechargeables in AF-7.
SLRs are different. Because they cost more, Ricoh built circuit of XR-X (XR-M) and similar models to tolerate use of Ni-Mh rechargeables. Compacts were cheaper so no reason to make them perfect.
