•  Take the following precautions to avoid risk of fire or electric shock:  

- Do not handle the power plug with wet hands.  
- Use only the power cord provided with the instrument. 

•  Connect the cables carefully so there are no problems operating the instrument. 

•  Always turn off the power and unplug the power cord before connecting the cables of any 

external devices to the TX-20.

•  Use the computer and other equipment that conform to the system standard IEC 60601-1 or 

IEC 60950-1 for the Full Auto Tonometer TX-20. Be sure that the entire system conforms to 
IEC 60601-1-1. Be sure to also use an isolation transformer conforming to IEC 60601-1 when a 
computer conforming to IEC 60950-1 is used.  
Otherwise, electric shock may occur. Ask your sales representative or local Canon dealer to 
connect it to a computer.

•  If the LAN connector is being used to connect to a network, connect an isolation transformer for 

networks between the TX-20 and network devices (HUB etc.) and between network devices. 
If this is not done, there is a risk of short circuits or malfunctioning devices. Ask your sales 
representative or local Canon dealer to connect it to a network. 

Make sure that the power switch is off. 

Connect a USB cable to input patient IDs with USB devices. 

Remove the paper from the printer before turning the TX-20 on its side to attach cables. Otherwise 
the paper may jam.

•  Always turn off the power and unplug the power cord before connecting the USB cable to the 

TX-20. 

•  For details on USB devices for inputting patient ID, contact your sales representative or local 

Canon dealer.
