The RT200 series Head Unit use CR2032, 3-Volt Lithium button Cell batteries. Battery Run Time (1 hour training / day): Approx.12 months (RT255/255L/277); Approx. 8 months (RT288/288L)

Important:

Most cycle computer problems are caused by weak or dead batteries. See the Trouble Shooting section near the end of the manual for details.

1. Remove the battery cap from the bottom of the Head Unit using

a coin.

2. Install a new battery as shown with the positive (+) side facing out. Do not touch or bend any of the battery contacts during installation.

3. Screw the battery cap firmly into place and make sure that the O-ring seal does not get pinched or distorted.

Caution:

To avoid damage to the battery cap, do not over tighten.

HEAD UNIT

The WL Wireless Speed Transmitter uses an A23, 12-Volt battery. Remove the battery compartment using a coin and install the battery in it with positive (+) side in, then replace the battery compartment. Battery Run Time (1 hour training / day): Approx.10 months

WL WIRELESS SPEED TRANSMITTER (

RT288/288L)

A23, 12V

Attach the Wired Speed Sensor with the Zip-Tie supplied and tighten the Bladed Spoke Magnet to the bicycle. Mounting the sensor as high up as on the fork leg. (Fig. A) Adjust the sensor and magnet spacing with the Spacer. Remove the Spacer after snugging the Zip-Tie down to hold the sensor in its final position.

WL WIRELESS SPEED TRANSMITTER & MAGNET (

RT288/288L)

Tie the WL Wireless Speed Transmitter with Bracket Rubber Pad loosely by the Zip-Ties supplied to either in the front of the left fork leg (see Fig.1 A) or at the back of the right fork leg (see Fig.1 B). For best signal reception, make sure the

distance between the Transmitter and the Head Unit is within 70 cm. At the same time, the Transmitter should be 2 ~ 4 cm (or more) away from the brake, to avoid blocking transmission signals by the brake. Adjust the transmitter

and magnet spacing with the Spacer. Slide and rotate the transmitter until the alignment mark just touches the spacer tip on the magnet. Remove the Spacer after snugging the Zip-Tie down to hold the transmitter in its final position.

INSTALLATION TESTS

Once installation is complete, the computer should be tested to make sure it is working properly.

To test the Speed Sensor/Transmitter installation:

Pick up the front of the bicycle and spin the front wheel. The LCD should display a speed- reading within 2-3 seconds.

To test the Cadence Sensor installation (RT277):

Advance the LCD to the CAD Mode using or . Turn the crank backwards or ride the bicycle a short distance. After a few revolutions, a cadence reading should display on the LCD.

If there is no spe ed-reading or cadence read ing, check the alignment and spacing between the magnet an d sensor/transmitter. Make sure that the Head Unit is completely locked into position. If these checks do not solve the problem, talk to an Authorized Vetta’s Retailer or connect to www.vetta.com

Important:

Make sure the magnets locking screw and all Zip-Ties are properly tightened.

TROUBLE SHOOTING

Current speed-reading is erratic or does not appear.

Check the alignment of the bladed spoke magnet and sensor/transmitter, and the distance between the two components. Realign the magnet and sensor/transmitter with the spacer. OR Inspect the wiring for any breaks or kinks. Replace Mounting Bracket and sensor as needed. (RT 255/255L/277)

Incorrect data appears on screen during operation.

Accuracy of the Setup data may be a problem (wheel size setting, etc.). Review data in System Check mode and revise as needed.
