IMPORTANT! PLEASE READ!
SpeedAngle Lap Timer is a device with high technology and powerful algorithm. It is
capable of calculating and producing lean angle measurement real time, and then listing
the results in the Angle History and the Max Angle elds. However, there are times when
the real time lean angle measurement might be exaggerated, such as when:
• You are maneuvering your bike in a way that is outside normal sportsbike motion,
such as moving the bike backwards, having a highside/lowside, or pulling a wheelie,
etc..
• You are curving around a bend by turning your handle bar at a great angle (especially
at a low speed),
• The wheel hits an obstacle or a pothole and causes the bike to bounce,
• You are curving around a bend whose slope changes midway,
• The vibration is too much.
More often than not, this is because the G-force behavior is not one of normal bike
movement, or the long axis of the motorcycle body does not point to the traveling direc-
tion ahead due to twist. The GMOS Core is constantly examining if such interaction
exists every time a turn is completed. If the answer is yes, it will compensate the interac-
tion and re-produce measurement results after the calibration. As the records of the
Angle History and Max Angle elds are updated after the calibration process, while the
pointer of the lean angle meter is in sync with the real time measurement, you might see
the reading of the latter larger than the former when the calibration is in effect. In such
cases, the reading of the Angle History and Max Angles should be taken as valid.
Please note that all the logged data have been calibrated.
Please also note that, in the rare cases where the interaction is too severe to be com-
pensated by the calibration mechanism, the calibrated lean angle measurement might
still be exaggerated (sometimes to as high as 69 degrees) or be discarded as invalid by
the GMOS Filter.

ers’ for further improvement.
GMOS at a Glance
Your GMOS comes with a dashboard unit and a sensor. The dashboard unit re-
ceives GPS signals, processes and stores the data transmitted from the sensor, and
communicates with the computer. The sensor is responsible for sensing the lean
angles of the motorcycle, and transmits them to the dashboard. Below are overviews
of the dashboard unit and the sensor.

The holes marked at the ends of the red
lines conform to AMPS hole pattern (a pat-
tern adopted by many mount manufacturers)
diagonally. Other holes form squares and
equilateral triangles. This makes it easy to ad-
just tting angles if you are making your own
mount.
The left claws are taller than the right claws

The installation of the GMOS dashboard unit and sensor unit is easy. No drilling
or wiring is required. After the installation, please remember to align the sensor as
instructed, and then you are ready to go.
Installing Dashboard Unit
Location
Please install the dashboard at the front beyond the steering stem area and keep it
clearly visible to the sky.
Best Might be obstructed from the sky
Installation
To install the dashboard, please install the bracket first. You can either use the
supplied 3M Dual Lock tape and adhere the bracket to a place you like, or buy an
AMPS hole pattern mount from the market and bolt the bracket to the mount.
With 3M Dual Lock Tape
To use , clean the mounting surface and the back of the brack-
et with alcohol and wipe dry. Keep the SA logo rightside up.
Apply the joined pieces to the back of the bracket and press
the bracket to the mounting surface. Let sit for at least 24 hours
after the application to obtain the best bonding strength.

the corresponding holes on the mount plate. Then bolt them together.
With a Hand-made Mount
If you would like to make your own mount plate, no problem. The hole pattern on the
bracket is designed to form as many equilateral triangles and squares as possible to
allow you the maximum freedom when adjusting tting orientations. Below are two
examples:

Installation Orientation
Clean the mounting surface with alcohol and let dry. Make sure the “UP” lettering is
pointing upward, and “FRONT” to the front. With the supplied red sponge tape, ad-
here the sensor to the installation location. Please also make sure the sensor cable
is secured.
Signs That the Installation Is Not Correct
Consider changing the installation location if
you see the lean angle meter needle moving
erratically during a turn in Drive Mode, or
you see such lean angle graph pattern as
the gure to the right in the analysis software
SpeedAngle R4:
If your angle shows a similar graph pattern in R4 as below, the sensor is installed in
a wrong direction. Make sure the “FRONT” on the sensor case is pointed to the front
of the bike.
The bike is leaning into a
turn, but the angle degree
measured is near 0: too much
vibration.
These peak-like lean angle
patterns are also a result of
too much vibration.

Installing GMOS 9
Installation Checklist
After installation, please use this checklist to help ensure the installation is correct.
□ Is the sensor installed to a location that will not move, swing, wag, or turn?
□ Is the sensor installed to a location with least vibration?
□ Is the sensor parallel to the longitudinal center line of the bike and vertical to the
ground when the bike is upright?
□ Is the “UP” lettering pointing upward and “FRONT” to the front of the bike?
Connecting Sensor to Dashboard
When connecting the sensor to the dashboard unit, make sure the arrows on the
cable heads align with each other. Insert the plug into the receptacle until you hear a
click. Connect the sensor before you turn the device power on.
NOTE: If the sensor is
connected AFTER the
power is on, it will not
be recognized by the
device.
You can choose not to connect the sensor and use the dash-
board alone as a simple lap timer. In this case, no lean angle
data will be collected. As a reminder, a “NO SENSOR”message
will appear where the G-force bar is. If later you would like to
reconnect the sensor, remember to turn the power off before
the connection.

USING GMOS
Charging GMOS
For safety purposes, the battery that comes with your GMOS has just enough
charge to sustain a working voltage. Please charge the battery before starting using
your GMOS.
To charge the battery, please use the supplied USB cable to connect your GMOS
with a computer, an external battery pack charger, or an AC-USB converter plug,
and then insert the plug to a wall outlet.
Once the charging starts, you will see a red light blink on on the top right corner.
Please make sure both the power and the backlight are off during charging; other-
wise, the battery will never be full. The red light will go off once the the charging is
complete. Normally, this will take about 2.5 hours.
If you are going to put GMOS away for a couple of months or more, DO NOT store
it on an empty battery. Keep it in an environment near 20˚C (68˚F). Otherwise, the
battery life might be reduced severely.
Getting Started
When GMOS is powered on, you will see the Welcome Screen
appear, displaying your User ID (can be edited via SpeedAngle
R3), GMOS model, and its registration number for 5 seconds.
You can press any key to skip the wait.
Then GMOS will display the Liability Screen. Please read it
carefully. Then GMOS will enter Drive mode or Timer Mode
automatically, depending on which Mode you were in when you
turned GMOS off last time. Please note that data are not shared
between modes.
In Drive mode, GMOS displays your speeds, lean angles, and G’s, and record these
data plus GPS traces. In Timer Mode, GMOS displays the speeds, G’s, and lap
times, and records these data plus lean angles and GPS traces.

Icons and Their Functions:
1GPS Antenna Icon
indicates the quality of GPS signal reception. The more vertical lines the icon
displays, the better the reception, and thus the higher the positioning accuracy.
• If there are less than 4 satellites locked, the GPS Antenna Icon will not be
displayed. This will not interrupt ongoing log recording. However, if this hap-
pens when you are pressing SELECT to start a new log, the system will not
start recording. Instead, a “POSITIONING” message will appear for about 2
seconds in the Message Area. The GPS Antenna Icon will reappear when
the positioning process is completed. Then you can press SELECT again
to start recording a new log.
2REC Icon
flashes when GMOS is recording. The icon will flash faster when there is
about 50 minutes of memory left, at double speed when there is about 10 min-
utes left, and stays visible when the memory is full.

Using GMOS 12
• The max log time is 7 hours or 254 logs.
• If the REC Icon does not appear after you press SELECT to start recording,
this means the system can not record logs. A message will be displayed in
the Message Area indicating the reason: the GPS module is still position-
ing; the memory is full; or the number of logs has reached 254. Please refer
to 10. Message Area (p.14) for more information.
• Entering System Menu will not interrupt recording, unless you go on to en-
ter Timer Mode.
• To clear the logs, you can either download and clear them with the Speed-
Angle R3 software, or go to System Menu and select “CLEAR MEMORY” to
clear them directly.
3Temperature Alert
ashes when the environmental temperature is below or above the operating
temperature range of the sensor (36°F ~ 140°F or 2°C ~ 60°C). flashes
when the temperature is below 36°F (2°C), while ashes when the tempera-
ture is above 140°F (60°C).
• Environmental temperature below or above the sensor’s operating tempera-
ture range might affect measurement accuracy.
4Battery Icon
indicates the charge of the battery.
• When the battery is almost empty, a “LOW BATTERY!”
message will be prompted. Please recharge GMOS as

• To clear the record, please go to System Menu and select “RESET MAX
ANGLE”.
9Lean Angle Meter
shows real time lean angle up to left / right 69 degrees.
10 Message Area
displays messages about log recording. The message will be displayed for
about 2 seconds. There are ve messages that may appear in the Message
Area:
START LOGGING / END LOGGING
displayed when GMOS starts / ends data recording. This
is an additional reminder besides the REC icon.
POSITIONING:
displayed when SELECT is pressed to start recording,
but there are not enough satellites to provide all the GPS
positioning data necessary for starting a new log, such as
location, time, and date. The system will continue search-
ing for more satellites. Sometimes this may take up to a
few minutes. During this process, the GPS Antenna Icon
will not be displayed. When you see the GPS Antenna

Auto Features
Youe SpeedAngle lap timer is basically hands-free. The best way to use it is turn
on the power and then DO NOTHING, unless you have multiple settings available
for the track and need to choose one. Focus on your ride; It will take care of itself.
With convenience in mind, the SpeedAngle lap timer auto features include:
Auto features What it does
Auto Track Search searching for Track settings available within 3KM auto-
matically after GPS positioning is complete
Auto Finish Line Setup drawing a Finish Line automatically where the Timer
starting speed is reached when no track settings can be
found or when being designated to. (This setting will be
saved to Track 15 only)
Auto Timer Start starting the Timer automatically when the pre-set starting
speed is reached,
