Wireless Sensor Information
The sensor is designed to receive signals within a maximum range of 70 cm to reduce interference. Signals may not be received if the distance is too great, or if the transmission distance is shorter due to low temperature or low battery. Signals are only received when the back of the computer faces the sensor.
Interference may occur, resulting in incorrect data, if the computer is:
- Near a TV, PC, radio, motor, or in a car or train.
- Close to a railroad crossing, railway tracks, TV stations, and/or radar base.
- Used with other wireless devices in close proximity.
This device complies with Part 15 of the FCC Rules. Operation is subject to two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Modifications not expressly approved by CatEye Co., Ltd. may void the user's authority to operate the equipment.
