B. INSTALLATION
BRACKET, H/BAR RUBBER PAD AND MAIN UNIT MOUNTING
1. Choose the proper thickness rubber pad(s) to fit your handlebar. Assemble bracket together by using screw
(M4 x 12mm) and nut (M4). Mount BRACKET & HANDLEBAR RUBBER PAD(S) (7) on handlebar by using screw
(M4 x 18mm) and nut (M4) to tighten the bracket and rubber pad(s). (Fig. A)
2. Mount main unit by sliding onto bracket from front. Unit will lock into position. To remove unit, press down
LOCK LEVER and slide unit forward. (Fig. B)
SENSOR AND MAGNET MOUNTING
1. Assemble SENSOR (9) and SENSOR BAND (11) together using screw (17). Slide BAND CARRIER (12) onto sensor
band. (Fig. C)
2. Mount MAGNET (14) on spoke facing sensor. Be sure it is centered in sensor zone (Fig. H). Use RING (13)
as shown in Fig. G to stabilize magnet.
3. Mount sensor on fork (Fig. D). Mounting position should allow the following mounting requirements.
A) Sensor unit should be within 45cm (18") of main unit. (Fig. F)
B) Sensor can be mounted upside down (Fig. E), however, note that sensor should be mounted closer to main
unit if done so.
C) Sensor should be aimed at main unit, +/- 15 degrees. Best angle is 90 degrees to main unit. (Fig. F)
D) Magnet should have 5mm (0.2") gap or less from sensor. (Fig. H)
4. Refer to TEST section for testing installation before tightening sensor band. (Fig. I)

TEST
The main unit has an automatic detection circuit to turn the unit on and off when installed and removed from bracket. The main unit will only receive wheel signals when it is mounted in bracket. The " " icon will indicate if the wireless signal is being received and your installation is correct. Check relative positions of main unit/sensor and sensor/magnet or refer to the troubleshooting section if problems with installation exist.
C. WIRELESS SYSTEM AND PERFORMANCE
1. The sensor sends an electronic signal to the main unit via wireless transmission. To prevent main unit from
receiving false data, mount all components within required distances outline in INSTALLATION section.
2. Important notes:
A) This computer has excellent EMI (Electro-Magnetic Interference) immunity between two bicycles with similar
wireless computers as long as distance between sensor and main units between bikes is over 40cm (15.8").
B) Main unit may experience data error around strong EMI signals. ie TV transmission stations, radar stations,
certain heavy industrial machines, etc.
3. Auto-detection circuit in main unit will reduce power consumption of receiver when unit is removed from bracket.
This is also helpful against error data received from PC monitors, cellular phones, etc., when main unit is not
mounted in bracket. Normal operation will resume when main unit is installed in bracket.
D. FUNCTIONS AND SPECIFICATIONS
: Current Speed 0.0~199.9 Km/h or 120.0 Mile/h +/- 1% (Typical)
1. Current speed is always displayed using the large display set.
2. Main unit will continue to display speed up to 4 seconds after bicycle has stopped to confirm no other wheel
signals are being received.
