ESD prevention

WARNING!
Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range of
1 to 10 megohm (Mohm) between a human body and the ground.
To prevent electrostatic discharge (ESD), follow these guidelines:
Make sure the router and the floor are reliably grounded.

 Keep the equipment room clean to reduce the negative effects of dusts and particles.
Maintain the humidity and temperature levels in the acceptable range.

Always wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is

reliably grounded.
No ESD wrist strap is provided with the router. Prepare it yourself.
To attach an ESD wrist strap:
1. Wear the wrist strap on your wrist.
