Important Notice 

Due to the nature of wireless communications, transmission and reception of data can never 

be  guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although 
significant delays or losses of data are rare when wireless devices such as the Chonghan Wireless 
device are used in a normal manner with a well

constructed network, the Chonghan Wireless 

device should not be used in situations where failure to transmit or receive data could result in 
damage of any kind to the user or any other party, including but not limited to personal injury, 
death, or loss of property. Chonghan Wireless accepts no responsibility for damages of any kind 
resulting from delays or errors in data transmitted or received using the Chonghan Wireless device, 
or for failure of the Chonghan Wireless device to transmit or receive such data. 

Safety and Hazards 

Do not operate the Chonghan Wireless device in areas where blasting is in progress, where 

explosive atmospheres may be present, near medical equipment, near life support equipment, or 
any equipment which may be susceptible to any form of radio interference. In such areas, the 
Chonghan Wireless device MUST BE POWERED OFF. The Chonghan Wireless device can transmit 
signals that could interfere with this equipment. Do not operate the Chonghan Wireless device in 
any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the Chonghan Wireless 
device MUST BE  POWERED OFF. When operating, the Chonghan Wireless device can transmit 
signals that could interfere with various onboard systems. 

Note: Some airlines may permit the use of cellular phones while the aircraft 
is on the ground and the door is open. Chonghan Wireless device may be 
used at this time. 

The driver or operator of any vehicle should not operate the Chonghan Wireless device while 

in control of a vehicle. Doing so will detract from the driver or operator’s control and operation of 
that vehicle. In some states and provinces, operating such communications devices while in control 
of a vehicle is an offence.
