ATTEN
TION
The AWK
-3121 is NOT a portable mobile device and should be
located at least 20 cm away from the human body.
The AWK
-3121 is NOT
designed for the general public. To deploy
AWK
-3121s and establish a wireless network safely, a
well
-trained technician is required for installation.
ATTENTION
Use the antennas correctly: The 2.4 GHz antennas are needed
when the AWK
-3121 operates in IEEE 802.11b/g. The 5 GHz
antennas are needed for IEEE802.11a. Make sure your antenna
installation is within a safety area, which is covered by a lightning
protection or surge arrest system.
