Cautions Before Assembly

Be careful of injury when handling parts

Use caution not to injure yourself due to the protruding parts when 
handling the circuit board. Use cotton work gloves to protect your hands 
when working. Also, be sure to wash your hands thoroughly after working.

Tighten screws and nuts at a perpendicular angle

Tightening screws and nuts that are inserted diagonally may damage the 
threads, making it impossible to tighten them again. Be sure to tighten 
screws so that they are inserted perpendicular to the surface.
Use caution, as applying too much torque and tightening the screws too 
tightly may damage the parts.

Do not injure yourself or scratch the surface with the 
tools.

When using tools to tighten screws and nuts, make sure not to injure 
yourself, such as by getting your fingers pinched. Work carefully to avoid 
scratching the case or circuit board with the tools.
Provide a sufficiently large work space to complete the assembly procedure, 
and prepare work mats so parts will not be scratched.

Avoid losing the screws and nuts

Handle the screws and nuts with caution, to avoid losing them. Do not use 
other screws or nuts aside from the ones included with this kit, and do not 
use the screws and nuts included with this kit for any other purpose.

Tools to prepare

You will need the following tools in order to assemble this kit.

Note:  

You will also need the AA alkaline batteries and so on. These items are 
not included, so please obtain them separately.

• 

Precision screwdriver (Phillips head No. 0, No. 1, flathead 2.4 mm)

Use a screwdriver that matches the size of the screw. Using the wrong 
size of screwdriver may damage the screw or make it impossible to 
tighten.

• 

Wrench (two-sided, 10 mm wide)

Checking the parts

Before assembly, make sure that all parts are on hand. (Page 6, Page 8)
