To test for proper installa-
tion of the magnet, trans-
mitter and Computer, acti-
vate the Computer by push-
ing the ‘MODE’ (right side)
button. Pick up the front of
the bicycle and spin the
front wheel. The “wheel
option” indicator will flash.
If it does not flash, check
the sensor and magnet
alignment. Realign as nec-
essary until the “wheel
option” indicator flashes
while spinning the wheel
OPERATION AND
PROGRAMMING
When your Turbo® Comp
has not detected any speed
input for 30 minutes, it will
enter sleep-mode in order
to conserve battery power.
During sleep mode only the
digital clock is displayed.
The computer will wake it
up when wheel speed is
detected or when the
MODE or SET button is
pressed. In order to oper-
ate your computer it must
be placed in various
“modes” (i.e. odometer
mode, distance mode). The
computer can be cycled
through these modes by
pressing the “MODE” but-
ton located on the right-
hand side the MODE/SET
rocker switch. There are
six cycling modes avail-
able: 1) Clock Mode, 2)
Odometer Mode, 3) Trip
Distance Mode 4) Average
Speed Mode, 5) Maximum
Speed Mode, 6) Automatic
Timer Mode. Once you
familiarize yourself with
the mode operation you
will find it very easy to
navigate. The following
flowchart outlines the
mode sequence. Once a
particular mode has been
entered, its values can be
reset or adjusted by press-
ing and holding the “SET ”
button for three seconds.
1. Setting the
5
cable tie-wraps provided to
position the sensor. Do not
tighten until the final place-
ment of the sensor magnet
is correct. (See figure 4).
Wheel magnets have been
provided for both tradition-
al round
spokes and
bladed (flat)
aerodynamic
spokes.
Attach the
magnet to a
spoke across
from the transmitter with
the magnet screw. The
clearance between the
magnet and the transmitter
should be approximately
1/32”-1/16”
(1-2mm).
Tighten the mag-
net and transmit-
ter. Do not over-
tighten the mag-
net screw. (See
figure 5).
For wheels with
bladed spokes:
Use some isopropyl (rub-
bing) alcohol or a mild
detergent to thoroughly
clean the spoke that you
plan to attach the magnet
to. Remove the backing
from the adhesive tape and
firmly press the magnet
onto spoke. The tape uses
a special pressure sensitive
adhesive. To ensure a
strong bond, please wait at
least 12 hours for the
adhesive to cure before
riding your bicycle.
Attach the appropriate
mount (26.0mm and
31.8mm sizes are includ-
ed) to the handlebar using
the bracket screw provid-
ed. Tighten so that the
bracket cannot rotate on
the handlebar. There are
several sizing straps pro-
vided to fit different diame-
ter bars. (See figure 6).
Slide the Computer for-
ward onto the mount until
it ‘snaps’ into place with
an audible click. Plug the
wire from the speed sensor
into the socket on the bot-
tom of your Computer To
remove the Computer,
remove the speed wire
then push it backward until
it releases from the mount.
