Battery Check - Mamiya M645 1000S User Manual

This camera is designed for use with
either silver oxide or alkaline batteries.
Although both types offer adequate
performance, silver oxide batteries
last much longer
IMPORTANT. When using the PD
Prism Finder, make it a point to use
silver oxide batteries when available
(in this instance, battery life is short-
ened if alkaline batteries are used)

Battery Check

When the battery check button (21,
located above the film advance knob)
is depressed, the battery check lamp
(8, located above the shutter speed
dial) illuminates. If the battery check
lamp fails to go on, it is time to replace
the battery.

* When the battery is completely ex-
hausted, the opened shutter will not
close. At this time,
if the battery check
button is pushed all the way down as
far as it will go, the shutter will then
close.
