ally installed by a qualified engineer familiar with system. Failure to properly install this product may result in physical injury and/or damage to property. Mounting Procedure The package contains screws for drop, open, and drywall ceiling mounting. Mounting Steps:

1. Determine the mounting location and verify that no wires, pipes, etc., are at the point of mounting. 2. Stick the Mounting Guiding sticker on the ceiling location. 3. Drill holes on the ceiling by follow drill guiding template. 4. Place the Power Adapter connected with the power cord into the bracket. 5. Place the bracket and threaded rod then lock the screws to fix the bracket on the ceiling. Note: One rod with 3 screws. First screw is to lock the bracket with the nut. The other two are to fix the rod between the ceiling. 4 Initial Installation 6. Slide the femto box into the bracket 7.Tighten the screw by hand and Plug the power cord Connecting GPS Antenna, Ethernet and Power Cable 1. Connect the GPS antenna cable (indoor use only) to the GPS port of the device. Note:

The GPS antenna must stay connected to the device at all times for operation. The initial GPS fix can take up to 60 minutes and may require an external outdoor GPS antenna(not supplied). 2. Attach the supplied Ethernet (Cat 7) cable from your router or modem LAN port to the device WAN port for network connectivity. 5 3. Plug the power cord into the power socket. Automatic power up will begin. POWER ON At Startup, the device will conduct self-configuration. This may take between 30-60 minutes the first time the device is turned on. 6 Chapter 3 Specifications General Specification 3 Connectivity
