Battery check
If the batteries have been inserted correctly,
the liquid-crystal display will come on within
ten seconds. To check whether battery capacity
is sufficient, set the data-imprint switch at
"MAN." and press the manual-imprint button
(before loading film) to make sure that the
display does not start blinking on and off
continuously.
Thereafter,
the
unit
auto¬
matically monitors battery capacity once each
hour and each time data Is imprinted. When
battery power drops to a level almost insuffi¬
cient for operation, the display will begin to
blink on and off to indicate that new batteries
should be inserted as soon as possible. When the
batteries are completely exhausted, the display
will be blank.
Cold-weather operation
Since batteries tend to lose power as tem¬
perature drops, always use fresh batteries and
keep a spare set with you when using the
Multi-Function
Back
in
cold
weather.
For
sustained cold-weather use
(approx. 0°C or
lower), it is recommended to use lithium or
silver-oxide batteries. Battery capacity will be
restored when temperature returns to normal.
