• Do not operate in flammable or explosive environments.
• Never operate with a power cord other than the one provided with your unit.
• Check that the power cord is not cracked, frayed or damaged before 

connecting to device and powering up.

• Remove and or disconnect main power before attempting any maintenance or 

fuse replacement.

• Do not connect and or operate this unit to a non-grounded, non-polarized 

outlet or power source.

• Do not connect the serial port or reference probe port to equipment with 

exposed, hazardous, live voltages.

• Any connections to the serial port or reference port should be made with Class 

II insulation or better.

• Protect from moisture or rain.

There are no user serviceable parts inside your unit. Attempting to repair or service your unit 

may void your warranty.

1.2
