8.1 Preventive Steps
Please follow these preventive steps to ensure the proper operation of your
instrument.

Never place heavy objects on the instrument.

Never place a hot soldering iron on or near the instrument.

Never insert wires, pins, or other metal objects into ventilation fan.

Never move or pull the instrument with power cord or output lead. More
importantly, never move the instrument when the power cord or output
lead is connected.

Do not obstruct the ventilation holes in the rear panel as this will increase
the internal temperature.

Do not operate the instrument with the cover removed unless you are a
qualified service technician.

Clean and recalibrate the instrument on a regular basis to keep the
instrument looking nice and working well.

Remove any dirt, dust, and grime whenever they become noticeable on the
outside cover using a soft cloth moistened with a mild cleaning solution.
8.2 When the Unit is Not Turning On
Check if the power ON/OFF switch is turned ON. If not, then check the power cord.
Please make sure that the power cord is properly connected to the unit. Please also
check the main switch and ensure that the AC supply at your site is the same as the
one mentioned at the rear chassis of the unit. Check for a blown fuse.
