Note1: When designing power supply, take measures prevention surge voltage. Note2: power supply lines (VDDB GNDB) have large ripple voltage during luminance control lamps. There possibility that ripple voltage produces acoustic noise signal wave noise audio circuit capacitor (5,000 6,000F) between power supply lines (VDDB GNDB) reduce noise, noise occurred circuit.

PRECAUTIONS MEANING CAUTION SIGNS following caution signs have very important meaning. sure read "4.2 CAUTIONS" "4.3 ATTENTIONS", after understanding these contents!
This sign meaning that customer will injured himself product will sustain damage, customer wrong operations. This sign meaning that customer will electrical shock, customer wrong operations. This sign meaning that customer will injured himself, customer wrong operations.
CAUTIONS touch inverter while inverter working, because there danger electric shock. remove inverter protection sheet, because there danger electric shock. sure wait some time after turning power before starting replacement work, because inverter charged high voltage after working. sure wait some time after turning power before starting replacement work, because inverter after working. shock inverter, because there danger breaking.
ATTENTIONS
4.3.1 Handling product Take hold both ends without touching circuit board when product (INVERTER) picked from inner packing avoid broken down misadjustment, because stress mounting parts circuit board. When handling product, take measures electrostatic discharge with such earth band, ionic shower because product damaged electrostatic. push-pull interface connectors while product working. hook pull cables such lamp cable, order avoid damage. Properly connect adaptable plug (backlight side) socket (inverter side) without incomplete connection. After connecting, careful hook lamp cables because incomplete connection occur hooking lamp cables. This incomplete connection cause abnormal operation high voltage circuit. Adaptable modules product cold cathode fluorescent lamps. After product stored under condition temperature dark place long time, cold cathode fluorescent lamp turned under same condition because general characteristic cold cathode fluorescent lamp. addition, when Luminance control ratio low, lamp turned this case, power should supplied again.

4.3.2 Environment operate store high temperature, high humidity, dewdrop atmosphere corrosive gases. Keep product packing with antistatic pouch room temperature avoid dusts sunlight, when storing product. order prevent condensation occurring temperature difference, product packing should opened after enough time being left under environment unpacking room. Evaluate leaving time sufficiently because situation condensation occurring changed environmental temperature humidity. (Recommended leaving time: hours more with packing state) operate high magnetic field. Product broken down This product designed radiation hardened. 4.3.3 Other GNDB VDDB terminals should used without non-connected lines. disassemble product. Pack product with original shipping package, order avoid damages during transportation, when returning product NEC. spacer between inverter board mounting surface, because protection contortion preservation special distance. Mounting method example Metal spacer Sheet metal Mounting surface Inverter board Inverter protection cover 11.5mm (min.)
