CAUTION:
•
Check the resistance of the ESD-preventive wrist strap for safety. The resistance reading should be in the
range of 1 to 10 megohm (Mohm) between human body and the ground.
• The SR6602-X does not provide any ESD-preventive wrist strap. Prepare it yourself.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the router and application system,
adversely affect the router in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including grounding system) coupling. To
prevent EMI, perform the following tasks:
• Take measures against interference from the power grid.
• Do not use the router together with the grounding equipment or light-prevention equipment of
power equipment, and keep the router far away from them.
• Keep the router far away from high-power radio launchers, radars, and equipment with high
frequency or high current.
NOTE:
Use electromagnetic shielding when necessary.
Lightning protection
To protect the router from lightning better, do as follows:
• Make sure the chassis is well grounded.
• Make sure the grounding terminal of the AC power receptacle is well grounded.
