There are 2 basic approaches:
1. Have the meter adjusted for the higher voltage. Any Oly camera repair
person can do this. It's most cost effective as part of a CLA. Our list
repair experts John Hermanson, Camtech at <zuiko.com> and Clint at
<clintonr@xxxxxxxxxxxxxxxx> will do the job.
2. Put something in series with the battery to lower the effective
voltage. Most effective is a forward biased diode. Again 2 options:
a. The MR9 adapter is the shell of a battery that fits the camera with
a diode built in that holds a standard 1.5v silver oxide battery.
Available from Camtech and elsewhere.
b. Insert the diode directly in the battery circuit inside the camera.
Only for the mechano/electrically competent type. To quote John H.
"......it's either a 1N34A or a CDSH270 diode
(which is what I use now). There is only one wire, that's off the negative
side of the battery. Positive side of battery goes through camera casing.
Put the diode into the circuit with the band "pointing towards the battery".
I solder the diode in after the power switch under the top cover."

I would be very interested to know what is needed to convert a camera
to Silver Oxide battery capability. I have a couple of Olympus cameras
with good mercuries in them but the day will come when I need to
change them.
