USER SAFETY INFORMATION
24.
Access Points used should respect IEEE 802.11 standards as well as local Radio Frequency regulations. The
device will scan the available channels and connect to the Access Point on the channel where the SSID that is
configured on the device is available.
25.
The following table shows the radio channels allocated in different geographic areas in the world. For bands
802.11b and g, only channels 1, 6, 11 and 14 (Japan only) are non-overlapping; for band 802-11a, channels
shown represent non-overlapping channel numbers.

In order to achieve the best transmission rate, it is necessary that the facility where the device is operated can
provide good area coverage. Please consult the IT personnel of the facility to verify the proper WLAN
availability in the area where the device will be used.
27.
28.
RF wave propagation may be blocked or reduced by the environment where the device is used. Most common
areas where this may occur are: shielded rooms, elevators, underground rooms. In all such situations it is
recommended to move the device to a proper location where the WLAN frequencies are available.
