• 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.
• 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 the above
situations, it is recommended to move the device to a proper location and verify with the IT personnel of
the facility the areas where the WLAN signals are available.
