USING THE PRODUCT SAFELY
WARNING
!
CAUTION
!
■ Do not remove the product's covers and panels
Never remove the product's covers and panels for any purpose.
Otherwise, the user's electric shock or fire may be incurred.
■ Warning on using the product
Warning items given below are to avoid danger to user's body and life and
avoid the damage or deterioration of the product. Use the product, observing
the following warning and caution items.
■ Warning items on power supply
● Power supply voltage
The rated power supply voltages of the product are 100, 120, 220 and
240VAC. The rated power supply voltage for each product should be
confirmed by reading the label attached on the back of the product or by the
“rated” column shown in the instruction manual. The specification of power
cord attached to the products is rated to 125VAC for all products which are
designed to be used in the areas where commercial power supply voltage is
not higher than 125VAC. Accordingly, you must change the power cord if
you want to use the product at the power supply voltage higher than 125VAC.
If you use the product without changing power cord to 250VAC rated one,
electric shock or fire may be caused. When you used the product equipped
with power supply voltage switching system, please refer to the corresponding
chapter in the instruction manuals of each product.
● Power cord
(IMPORTANT) The attached power cord set can be used for
this device only.
If the attached power cord is damaged, stop using the product and call us or
your local dealer. If the power cord is used without the damage being
removed, an electric shock or fire may be caused.
● Protective fuse
If an input protective fuse is blown, the product does not operate. For a
product with external fuse holder, the fuse may be replaced. As for how to
replace the fuse, refer to the corresponding chapter in the instruction
manual. If no fuse replacement procedures are indicated, the user is not
permitted to replace it. In such case, keep the case closed and consult us
or your local dealer. If the fuse is incorrectly replaced, a fire may occur.

III
USING THE PRODUCT SAFELY
■ Warning item on Grounding
If the product has the GND terminal on the front or rear panel surface, be sure
to ground the product to safely use it.
■ Warnings on Installation environment
● Operating temperature and humidity
Use the product within the operating temperature indicated in the “rating”
temperature column. If the product is used with the vents of the product
blocked or in high ambient temperatures, a fire may occur. Use the product
within the operating humidity indicated in the “rating” humidity column.
Watch out for condensation by a sharp humidity change such as transfer to a
room with a different humidity. Also, do not operate the product with wet
hands. Otherwise, an electric shock or fire may occur.
● Use in gas
Use in and around a place where an inflammable or explosive gas or steam is
generated or stored may result in an explosion and fire. Do not operate the
product in such an environment. Also, use in and around a place where a
corrosive gas is generated or spreading causes a serious damage to the
product. Do not operate the product in such an environment.
● Installation place
Do not insert metal and inflammable materials into the product from its vent
and spill water on it. Otherwise, electric shock or fire may occur.
■ Do not let foreign matter in
Do not insert metal and inflammable materials into the product from its vent
and spill water on it. Otherwise, electric shock or fire may occur.
■ Warning item on abnormality while in use
If smoke or fire is generated from the product while in use, stop using the
product, turn off the switch, and remove the power cord plug from the outlet.
After confirming that no other devices catch fire, ask us or your local dealer.

IV
USING THE PRODUCT SAFELY
■ Input / Output terminals
Maximum input to terminal is specified to prevent the product from being
damaged. Do not supply input, exceeding the specifications that are indicated
in the "Rating" column in the instruction manual of the product. Also, do not
supply power to the output terminals from the outside. Otherwise, a product
failure is caused.
■ Calibration
Although the performance and specifications of the product are checked under
strict quality control during shipment from the factory, they may be deviated
more or less by deterioration of parts due to their aging or others.
It is recommended to periodically calibrate the product so that it is used with its
performance and specifications stable. For consultation about the product
calibration, ask us or your local dealer.
■ Daily Maintenance
When you clean off the dirt of the product covers, panels, and knobs, avoid
solvents such as thinner and benzene. Otherwise, the paint may peel off or
resin surface may be affected. To wipe off the covers, panels, and knobs, use
a soft cloth with neutral detergent in it.
During cleaning, be careful that water, detergents, or other foreign matters do
not get into the product.
If a liquid or metal gets into the product, an electric shock and fire are caused.
During cleaning, remove the power cord plug from the outlet.
Use the product correctly and safely, observing the above warning and caution
items. Because the instruction manual indicates caution items even in
individual items, observe those caution items to correctly use the product.
If you have questions or comments about the manuals, ask us or E-Mail us.

2. QUICK REFERENCE
This chapter describes the operation shortcuts, built-in help and factory default
settings. This chapter is to be used as a quick reference, for detailed explanations
on parameters, settings and limitations, please see the operation chapters
2-1. How to use the Digital Inputs
Background
The FGX-2220 has three main types of digital inputs:
the number pad, arrow keys and scroll wheel. The
following instructions will show you how to use the
digital inputs to edit parameters.
1. To select a menu item, press
the corresponding function
keys below (F1~F5). For
example the function key F1
corresponds to the Soft key
“Sine”.
2. To edit a digital value, use
the arrow keys to move the
cursor to the digit that
needs to be edited.
3. Use the scroll wheel to edit
the parameter. Clockwise
increases the value, counter
clockwise decreases the
value.
4. Alternatively, the number pad
can be used to set the value of
a highlighted parameter.
