Introduction
Measurement using the ANT+ speed sensor and the GPS signal
For speed measurement, the speed can be calculated from the GPS signal, even if you do
not have the ANT+ speed sensor. When the speed signal from the ANT+ sensor is detected,
priority is given to the speed signal for measurement. The difference between the measure-
ment using the ANT+ speed sensor and that using the GPS signal is as follows.
Measurement using the GPS signal
Measurement using the
ANT+ speed sensor
Under mea-
surement
The unit may stop measurement or
may not display appropriate mea-
surements when the GPS signal
cannot be received due to locations
or environments while riding.
Accurate measurement can be
performed even in such locations or
environments where the GPS signal
cannot be received.
Measurement
results
The measurement results may differ
slightly from the actual value.
Highly reliable measurement values
can be obtained, since they are based
on wheel rotations.
* For GPS, see “GPS” (page 3).
ANT+ communication standards
ANT+ is low-power-consumption digital communication standards using frequency of 2.4GHz.
It practically prevents external noises and cross talks from interfering with measurement,
and enables to record and store more reliable data than before.
However, it suffers interference in the following places and/or environments, which may
result in an incorrect measurement.
* Be careful especially while pairing (i.e., searching the sensor ID).
• Near TVs, PCs, radios, motors, or in cars or trains.
• Near railroad crossings, along railway tracks, around television transmitting stations and
radar bases, etc.
• When using together with other wireless devices, or some particular battery lights.
• Under the Wi-Fi environment
Automatic recognition of the sensor ID
The ANT+ sensor has its own ID, and the computer measures in synchronization with the ID.
2 sensor IDs per sensor type can be registered into the computer. By pairing in advance, the
sensor is automatically recognized while riding. It is not necessary to change the tire circum-
ference manually, since the tire circumference is set for the speed sensor or speed/cadence
(ISC) sensor ID.
* The speed sensor or speed/cadence (ISC) sensor, whichever is recognized, is indicated by
the speed sensor icon ( , ) on the display.
Proper use of the CatEye STEALTH 50
Warning / Caution
• Do not concentrate on the computer while riding. Ride safely!
• Mount firmly the bracket on your bicycle, and check periodically that it is not loosened.
• Do not leave the computer in direct sunlight for a long period of time.
• Do not disassemble the computer.
• Do not drop the computer to avoid malfunction or damage.
• Be sure to tighten the dial of the FlexTight™ bracket by hand. Tightening it strongly using a
tool, etc. may damage the screw thread.
• When cleaning the computer and bracket, do not use thinners, benzene, or alcohol.
• LCD screen may be distorted when viewed through polarized sunglass lenses.
Cautions when measuring
Press and hold the MODE button to reset the computer before and after measurement.
Measuring starts by resetting the computer. The unit keeps recording the trip until it is
reset. Turn off the unit when not in use.
ANT+ sensor (optional or commercial)
This unit can receive, measure and display the signal from the following 4 ANT+ sensors.
• Speed sensor
• Speed/cadence (ISC) sensor
• Cadence sensor
* Heart rate sensor
• Power sensor
* For each type of sensor, you can perform pairing with up to 2 sensors.
* We offer an optional speed/cadence sensor (ISC-11), and heart rate sensor (HR-11).
* You can view applicable sensors on our website.
