Notes on Use
────────────────────────────────────────────────────
WARNING Before turning on the power, make sure that the voltage of the power
supply being used matches the supply voltage indicated on the rear
panel of the unit.
If an attempt is made to use an improper supply voltage, there is danger
of damage to this unit and of life-threatening risk to the operator.
The unit is constructed so as to be connected to a ground line via a
three-core power cord that is supplied with the unit. In order to avoid
electric shock, connect the unit to a properly grounded (3-pin) outlet
using the power cord provided.
The interior of the unit contains some components which are subject to
high voltage, and therefore dangerous. Absolutely do not remove the
cover panel.
To prevent electric shock, do not allow the unit to become wet and do
not use the unit when your hands are wet.
The unit should always be operated indoors in a range from 0℃to 40℃
and 30% to 90% RH. Do not use the unit in direct sunlight, dusty
conditions, or in the presence of corrosive gases.
Only use fuses of the specified type that is rated for the specified
current and voltage. Using a fuse that does not meet the specifications
or shorting the fuse holder may cause an accident that might result in
injury or death. (Specified fuse: 250 V T3.15 AL)
Notes on Use
In order to ensure safe operation and to obtain maximum performance from
the unit, observe the cautions listed below.
