① Do not operate or store in high temperature, high humidity,
dewdrop atmosphere or corrosive gases. Keep the product in packing
box and antistatic pouch in room temperature to avoid for dusts and
sunlight, when customer stores the product.
② In order to prevent dew condensation occurring by temperature
difference, the product packing box should be opened after being
left under the environment of an unpacking room enough. Because
asituation of dew condensation occurring is changed by the
environmental temperature and humidity. Evaluate the leaving time
sufficiently. (Recommendation leaving time: 6 hour or more with
③ Do not operate in high magnetic field. Circuit boards may be
broken down by it.
④ This product is not designed as radiation hardened.
① All GNDB and VDDB terminals should be used without any
② Do not disassemble a product.
③ Pack the product with original shipping package, in order to
avoid any damages during transportation, when returning the product
④ Put the spacer between inverter board and mounting surface,
because of the protection for contortion and the preservation of

When designing of the power supply, take the measures for the
prevention of surge voltage.
The power supply lines (VDDB and GNDB) have large ripple voltage
during luminance control of LCD lamps.
There is the possibility that the ripple voltage produces acoustic
noise and signal wave noise in audio circuit and so on.
Put a capacitor (5,000 to 6,000mF) between the power supply lines
(VDDB and GNDB) to reduce the noise,
if the noise occurred in the circuit.
