RF exposure statement
The Digi Connect Wi-Wave module complies with RF exposure limits for humans as
called out in RSS-102. It is exempt from RF evaluation based on its operating
frequency of 2.4 GHz, and effective radiated power less than the three watt
requirement for a mobile device (>20 cm separation) operating at 2.4 GHz.

Safety statements
To avoid contact with electrical current:
Never install electrical wiring during an electrical storm.
Use a screwdriver and other tools with insulated handles.
Wear safety glasses or goggles.
Installation of inside wiring may bring you close to electrical wire, conduit,
terminals and other electrical facilities. Extreme caution must be used to avoid
electrical shock from such facilities. Avoid contact with all such facilities.
Protectors and grounding wire placed by the service provider must not be
connected to, removed, or modified by the customer.
Do not touch or move the antenna(s) while the unit is transmitting or receiving.
Do not hold any component containing a radio such that the antenna is very
close to or touching any exposed parts of the body, especially the face or eyes,
while transmitting.
Do not operate a portable transmitter near unshielded blasting caps or in an
explosive environment unless it is a type especially qualified for such use.
