XW-110™ WiFi Temperature Sensor Users Manual

Introduction

1.1.3   Wireless Communication Notes

Due to the nature of wireless communications, transmission and reception of data can not be 
guaranteed. Data may be delayed, have errors, or be lost. Although delays or losses of data are rare 
with a well constructed network, data can be lost due to interference, noise, reflections, or other 
environmental conditions. The XW-110 should not be used in situations where failure to transmit or 
receive data could result in damage to property, equipment, direct, indirect, consequential, or incidental 
damage, including damage for loss of business profit, business interruption, loss of data, life, and the 
like.
