Preparing the Meter for Operation
1. Inserting the battery
The meter uses a single AA size pen-light battery
(1.5h. Open the battery chamber cover by sliding it in
the direction of arrow, and insert the battery carefully
aligning (+) and (-) polarities as indicated inside the
chamber.
Note: When not using the meter for a week or
more, remove the battery from the meter.
This will prevent any internal damage
arising from battery leakage.
2. Checking the battery
Check the battery before using the meter. A weak
battery will not assure the correct light readings.
Slide the power switch to ON position. Then the b.c.
mark and bar symbols will be displayed. Battery
capacity is indicated by the bar symbols (Fig. 1).
After checking battery (for about 0.5 sec.) the display
automatically changes to measuring mode (Fig. 2). If
the battery is too weak to give a correct light
readings, the b.c. mark will flash.
Note: If you switch the meter on while depressing
ISO key, the display of b.c. mark and bar
symbols will keep indicating.
3. Selecting measuring mode

4. Setting ISO sensitivity
Press either side of UP/DOWN key while
holding ISO key depressed so that the
ISO number of your film is displayed.
Film speed can be set within the range
of ISO 3 -ISO 8000 (Fig. 3).
5. Setting shutter speed
This meter is designed for T (shutter
speed) priority use, and the shutter speed
should be set first.
Press either side of UP/DOWN key, so the
display of shutter speed can be changed in the
range of 30 min.-1/8000 sec. for ambient light
measurement and 1 sec.-11500 sec. for flash
light measurement (Fig. 4).
After the display of 1/8000 sec. the tine scale
is indicated (8, 16, 18, 24, 32, 64 and 128
fps.). In case of tine mode, the symbol C is
displayed (Fig. 5).
Note: The set figures (ISO, shutter speed and
tine scale) are memorized even after
the meter is switched off.
Wireless Measurement using Electronic Flash Unit
In case the photographed subject is too far away to use a synchro cord, or in case
the synchro cord disturbs photographing, flash light can be measured without
connecting synchro cord.
