9. Label
The HiLo3G-850 is labeled with its own FCC ID (VW3HILO3G850) on its shield side. When the module is installed in
customer‘s product, the FCC ID label on the module will not be visible. To avoid this case, an exterior label must be stuck
on the surface of customer‘s product signally to indicate the FCC ID of the enclosed module. This label can use wording
such as the following: ―Contains Transmitter module FCC ID: VW3HILO3G850‖ or ―Contains FCC ID:
VW3HILO3G850‖.
