• Digital Multimeter (DMM) for voltage checks and confirming resistor values. A DMM with

capacitance measurement capability is desirable, but not required.

• Magnifying glass or visor.

Preventing Electrostatic Discharge Damage

The KXB8030 main PCB is sensitive to electrostatic discharge (ESD) damage. Also, the individual PCBs

in your KX1 may be vulnerable when they are unplugged.

• Keep parts in their ESD-safe packaging until called for in the assembly instructions. Do not place

individual PCBs in Styrofoam™ or similar containers. If possible, place loose PCBs inside ESD-

safe bags when you are not working on them.

• Wear a conductive wrist strap with a series 1 megohm resistor. If you do not have a wrist strap,

touch a ground briefly before touching any sensitive parts to discharge your body. Do this

frequently while you are working. You can collect a destructive static charge on your body just

sitting at the work bench. DO NOT attach a ground directly to yourself as this poses a serious

shock hazard.

• Make sure your soldering iron is ESD-safe and has a grounded tip

• Use a grounded antistatic mat on your work bench.

Note 1 : Duplicate reference designators are for parts on different PCBs. The parts are clearly identified in the text.

Note 2: The PCBs may have rough places along the edges. This is a normal result of the manufacturing process and will not

interfere with installation.
