FOR SAFE OPERATIONS (IMPORTANT)  
For safe and appropriate use, always observe the following.  
Caution:  
• Don't pay too much attention to your cyclocomputer functions when riding. Keep your eyes on the road and give due  
consideration to safe riding.  
E
• This altimeter is not intended to be a specialized measuring device.  
Proper use and care:  
Never disassemble the main unit. It can not be re-assembled.  
The main unit is loaded with sensitive components. A strong impact may result in malfunction. Don't intentionally submerge the  
main unit under water. Although the main unit is water-resistant (such as rain), it is not designed to be used underwater.  
Don't leave the main unit exposed to direct sunlight for extended periods of time.  
If the main unit is superheated by direct sunlight, the temperature sensor inside of the main unit will not give the correct tempera-  
ture.  
The Cat Eye CC-AT100 is essentially a barometer. It measures the change in barometric pressure whether caused by a change in  
altitude or a change in weather.  
The current altitude should be calibrated before each ride.  
Sudden temperature change can cause a temporary incorrect altitude display.  
When using this unit as an independent altimeter, switch off the bicycle symbol to allow it in the continuous measuring mode.  
Static electricity might cause incorrect data.  
If the S/S(Start/Stop) button, Mode button and Set button are pressed simultaneously, all the stored data will be erased.  
In an aircraft, the unit will not give a correct data because of the regulated pressure.  
Maintenance:  
When the main unit or the contact gets wet, dry it off with a cloth; rust will cause functional errors.  
Fasten the magnet and the speed sensor securely, and check their relative position periodically. Incorrect attachment of these  
parts may cause an accident.  
If the altitude sensor cover is clogged with mud or sand, it will stop measuring accurately. Clean it off according to "Daily Care"  
instructions.  
If the main unit or accessories/attachments become dirty with mud etc., gently wash with mild soap and wipe dry with a soft cloth.  
Never apply paint thinner, benzine or alcohol; damage will result.

2. Main Unit Preparation  
The following process must be completed before starting to use.  
-1. How to Measure Wheel Circumference  
L
In order to get the accurate value, measure the wheel circumference (L) actually from the tire of your  
bicycle (Fig. 2). Put a mark on the tire tread, and ride one full wheel revolution; then mark the ground at the  
end of one revolution and measure the distance between the two marks. Or, "Setting Values Cross Refer-  
ence Table" (page 19) can tell the approximate wheel circumference according to the tire size.  
Fig.2  
Fig.3  
-2. Setting Speed Scale  
First, press the AC button; all displays illuminate and then "km/h" symbol appears (Fig.3). With each press  
of the S/S button, "km/h" and "mile/h" appears alternately. Select the desired scale and press the Set  
button to fix the scale. This speed scale corresponds to the altitude scale; if "km/h" is selected, the altitude  
scale will be "meter", and if "mile/h" is selected, the altitude scale will be "feet".

zero and the data will be reset to the initial value of "International Standard Atmosphere" (ISO 2533).  
HOW TO USE AS AN ALTIMETER  
Correlation between above sea  
level and pressure  
extract from ISO 2533 (Table 1)  
1. Altimeter Function  
This unit, loaded with a pressure sensor, measures the altitude by using atmospheric pressure. It esti-  
mates the altitude by using the "correlation between altitude and pressure" of ISO 2533, based on the  
International Standard Atmosphere of ICAO (International Civil Aviation Organization). Generally, a con-  
ventional pressure sensor is affected by temperature and gives errors; but this unit is temperature-com-  
pensated every 20 seconds and records 1 meter resolution. Also, with a conventional altimeter, altitude  
data at the same venue varies from time to time because it is affected by the change of the pressure;  
however, the CATEYE CC-AT100 is not affected by pressure changes when not cycling. It measures three  
types of altitude data simultaneously: above sea level (current altitude), trip altitude gain (total of altitude  
gain from the start to the current point) and total altitude gain (accumulation).  
A.S.Level Pres. A.S.Level Pres.

3500 m 658 hPa 400 m 966 hPa  
3000 m 701 hPa 300 m 978 hPa

900 m 910 hPa 200 m 1038 hPa  
800 m 921 hPa 300 m 1050 hPa  
700 m 932 hPa  
Note: The current altitude data may give an incorrect value temporarily, such as when it is brought from  
indoor to outdoor, or when the energy-saving function is released. This is just an influence of the tem-  
perature change and is not a malfunction. It will quickly stabilize and return to normal.  
The Correlation Between Altitude and Pressure  
The higher the altitude gets, the lower the pressure becomes. At venues of which altitudes are under 500m, the pressure decreases by approx.  
12hPa per each 100m (Table 1).  
Weather and Barometric Pressure Changes  
Changes in weather from a HIGH PRESSURE system (clearer, calmer weather) to a LOW PRESSURE system (over-cast, rain, storming  
weather) can cause a change in the Altitude reading of 300 feet or more. Thunderstorms or other strong low pressure weather conditions, you

may cause even a greater change. In seemingly stable weather conditions, you  
may expect to see the Altitude fluctuate as much as 100 feet from morning to  
evening because of the warming aspects of the sun on the atmosphere.  
E
Fig.10  
2. Cycling Mode (Bicycle Symbol: on) (Fig. 10)  
When using this unit on bicycle, switch on the bicycle symbol. In this way, the  
change of the pressure will have an influence on the altitude data only when the  
unit perceives the speed signal, regardless of start/stop. Thus, the altitude data  
will not be affected even if pressure changes occur while bicycle is stopped. (Fig.  
11).

3. Continuous Measuring Mode (Bicycle Symbol: off)  
When using this unit on its own apart from a bicycle, for hiking etc., switch off the  
bicycle symbol. In this way, the altitude data is always influenced by the change of  
the pressure (Fig. 12).

4. How to Switch on/off the Bicycle Symbol  
To switch on(off) the bicycle symbol, first display the sub mode showing trip altitude gain and total altitude gain, with  
the operation of the Mode button, and press the Set button. Then press the Set button again, and the bicycle symbol  
will be switched on(off).  
5. How to Correct the Current Altitude  
Air pressure changes constantly, due to various weather conditions. As such, while riding, it is necessary to correct  
the altitude. It is recommended to make corrections whenever a reliable index (such as map or peak pointer) is  
available.  
* The basic knowledge of the altitudes of your house, public facilities, etc. will be useful information for correction.

How to Correct the Altitude  
First display the main mode showing  
, with the operation of the Mode button. Press the Set  
button when the speed is zero, and it turns to the correction mode (Fig.13). The figure increases with  
each press of the S/S button, and decreases with each press of the Mode button. To increase/  
decrease the number rapidly, hold down the button. Adjust the figure to the correct altitude, and  
press the Set button to complete this operation.
