Before connecting power cord, be sure to confirm that the power
voltage matches with the supply voltage.
Before connecting power cord, be sure to switch off the instrument.
Verify that there is no dangerous voltage on the terminals before
touching them.
To avoid fire or electric shock, make sure to use the power cord
supplied by ITECH.
Be sure to connect the main power socket to the power outlet with
protective grounding. Do not use terminal board without protective
grounding.
Do not use an extended power cord without protective grounding,
otherwise the protection function will fail.
Ensure that the input electrodes are either insulated or covered using
the safety covers provided, so that no accidental contact with lethal
voltages can occur.
If you notice strange sounds, unusual odors, fire, or smoke around or
from inside the instrument, flip the POWER switch to the (O) side to
turn the instrument off, or remove the power cord plug from the outlet.
The detachable power cord may be used as an emergency
disconnecting device. Removing the power cord will disconnect AC
input power to the unit.
