CRANKCASE INSTRUCTION MANUAL 09
USING THE TACHYMETER
The number scale around the rim of the dial face can be used to compute speed
based on travel time. Speed can be measured in miles per hour, kilometers per hour,
or another unit of measure per hour, but only speeds above “60” can be measured.
TO MEASURE SPEED
START TIMING AT MARKER
When you reach a distance marker
(such as a mile or kilometer marker),
press button “A”.
STOP TIMING AT NEXT MARKER
When you reach the next distance marker
(after traveling 1 mile or 1 kilometer),
press button “A” to stop timing.
The hand that counts seconds now
points to your speed on the tachymeter
scale. (Example: If mile markers were
used and the hand now points to “65,”
your speed is 65 mph.)
RESET
While timing is stopped, press button “B”.

USING THE ROTATING BEZEL
The top bezel can be rotated for an additional measure of time intervals. Rotate
the bezel counterclockwise to align the “60” mark (which is also the zero mark)
with the minute hand on the main dial face. After a time interval, use the
numbers on the bezel to read the elapsed time in minutes. Note that the bezel
rotates in only one direction.
POWER SAVING MODE
When the timepiece is not in use, the battery life can be prolonged by pulling the
crown out to the second click position (b). This will stop the hands and reduce
power consumption.
