6. Timer Selection
The SpeedZone® Pro has two timers;
Automatic Timer Mode (ATM) and
Timer Mode (TIMER). The ATM selec-
tion allows you to keep track of your
actual riding time. The timer only
operates when the wheel is rotating
and cannot be turned on or off manu-
ally. Note: The average speed (AVS)
calculation is based upon the ATM time.
The TIMER selection is just like a con-
ventional stopwatch. The timer is acti-
vated manually and records the time
whether the wheel is rotating or not.
Tapping the "TOP" button starts and
stops the stopwatch and holding the
"SET" button for three seconds will
reset to stopwatch. The TIMER
includes a 12-memory lap time fea-
ture. To record a lap time, press the
"SET" button once while the stop-
watch is running. Each time the "SET"

taneously until the display shows MM

represents your tire circumference in

until the flashing digit is correct.
(Note: The "MODE" button may be
held to scroll to the correct digit.)
Press the "SET" button to select the
next digit to the right. Repeat the
process until all four digits are
entered as your tire circumference.
Press the "SET" button once to select it
and enter the circumference for wheel
option #2. Follow the same procedure
to program the wheel #2 tire size and
tap the "SET" button to exit circumfer-
ence programming mode.
