System Overview

THE CERVO 2.4 SYSTEM

The Cervo 2.4 system includes a computer and harness which measures speed, dis-
tance, cadence (Pro), and heart rate. This information is transmitted via receiver placed
on the front fort. The receiver transfers the data via a wired signal to a

computer
mounted on the handlebar or stem. Heart rate data is transferred via a non-coded

telemetry signal from the chest strap monitor. The data is then integrated to display

current, average, and maximum biometric information.

PREPARING FOR INSTALLATION

The only item needed for installation in a cable cutter to trim excess cable tie. See
TABLE 1 to verify package con

tents..

UPGRADING TO POWERTAP
The Cervo is the same computer used with the PowerTap SL 2.4 models. Some of the
features on the Cervo will not function without the PowerTap hub and receiver. The
Cervo 2.4 can easily be upgraded to the PowerTap SL 2.4 by con

tacting your local

dealer or CycleOps directly at 800-783-7257.

SYSTEM INSTALLATION

1. Attach Sensor to Fork
Attach sensor to front fork so the magnet passes
within 3-5 inches of the sensor (FIGURE1). Place
cable tie through sensor to secure. Make sure the
logo side of the sensor faces the magnet.

3. Attach Computer Shoe to Handlebar or Stem
The receiver

shoe can be mounted on either the handlebar or stem. Secure the
mounting base with cable ties. Slide the computer shoe in the direction of the arrow
as depicted in either FIGURE 2A or 2B depending on mounting location.

4. Install Cadence Sensor (Pro)
Only

the Cervo Pro is able to measure cadence
with the included cadence sensor. First install
the pedal cadence sensor to the left chain stay
in line with the pedal spindle. Next attach

cadence magnet to the crank arm. Ensure the
center of the magnet passes the line

of the sen-

sor unit. Do not

center the magnet in relation to
the
sensor (FIGURE 3). See COMPUTER SETUP 4 to
correctly configure the computer for the chosen

method of cadence determination.

5. Place Computer into Computer Shoe
Place the computer into the mounting shoe

on the handlebar or
stem. Line up the slots on the base of the computer with the
bracket and slide computer toward the rider (FIGURE 4). NOTE:
Ensure the computer is fully inserted onto the receiver shoe for
proper data transmission.

6. Heart Rate Mon

itor Strap
Position the heart rate monitor strap on your torso as pic-
tured in FIGURE 5. The strap should rest just beneath the
pectoralis muscles of the chest. For best results slightly
moisten the electrodes where contact is made with skin.
The heart rate strap must be worn to enable the heart rate
function. NOTE: The chest strap for the Cervo2.4 uses a
coded frequency and is not compatible with other
manufacturer’s chest straps.

7. Verify Installation
Check to make sure all components are properly secured.
Spin wheel and verify that in the upper left hand corner of

the computer the transmission icon illuminates (FIGURE 6).
This indicates the sensor is properly transmitting a signal to
the computer. If the transmission icon is not illuminated
consult TROUBLESHOOTING for further instructions.
