• 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.

• Use a grounded anti-static mat on your work bench.

• If you choose to use a soldering iron to work on your K3 for any reason, be sure your iron has an ESD-

safe grounded tip tied to the same common ground used by your mat or wrist strap.

Preparing for Installation

Tools Required

1. #0 and #1 size Phillips screwdrivers. To avoid damaging screws and nuts, a power screwdriver is not

recommended. Use the screwdriver that best fits the screw in each step.

2. Small pliers or a 1/4” nut driver.

3. Soft cloth or clean, soft static dissipating pad to lay cabinet panels on to avoid scratching.

The following tools are strongly recommended:

1. ESD wrist strap.

2. Static dissipating work pad.
