FCC and IC RFI Statements/CE Mark
Federal Communications Commission and Industry Canada Radio Frequency Interference
Statements
This equipment generates, uses, and can radiate radio-frequency energy, and if not installed and used properly, that is, in strict
accordance with the manufacturer’s instructions, may cause inter ference to radio communication. It has been tested and found to
comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emis sion from digital apparatus set out in the Radio
Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de
la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.

Safety Instructions
Safety Instructions
CAUTION: Circuit devices are sensitive to static electricity, which can damage their delicate electronics. Dry weather conditions or
walking across a carpeted floor may cause you to acquire a static electrical charge.
To protect your device, always:
• Touch the metal chassis of your computer to ground the static electrical charge before you pick up the circuit device.
• Pick up the device by holding it on the left and right edges only.
• If you need to connect this device with outdoor devices, then you must add an arrester on the cable between the outdoor
device and this device.
NOTE: The switch is an indoor device; if it will be used in outdoor environment or connects with some outdoor device,
use a lightning arrester to protect the switch.
WARNING:
• Do not demolish the product. If damage is caused by self-demolition, you will be charged a fee for repair.
• Do not place the product outdoors or in a sandstorm.
• Before installation, make sure the input power supply and product specifications are compatible with each other.
• To reduce the risk of electric shock, disconnect all AC or DC power cords and cables to completely remove power from the unit.
• Before importing/exporting a configuration, make sure the firmware version is the same.
• After a firmware upgrade, the switch will replace the configuration automatically with the latest firmware version.
