Chapter 4 Configuring Your Device

External GPS Antenna

If your 4G LTE Network Extender cannot receive a GPS signal, it may be
necessary to improve the reception by installing the extension cable and then
repositioning the GPS antenna outside the unit. This section outlines the
installation and relocation of the external GPS antenna.

To relocate the GPS antenna of the Network Extender, follow these steps:

1 Turn off the Network Extender.
2 Firmly press down on the open groove (top right).
3 Slide the protective cover to the right to expose the rectangular GPS antenna.

4 Pull the GPS antenna away from the Network Extender.
5 Remove the GPS antenna from its compartment.
6 Connect the GPS antenna to one end of the provided GPS cable.
7 Connect and secure the other end to the port on the Network Extender (within

the GPS antenna compartment).

8 Place the antenna near a window where the GPS signal is stronger. You can

use double-sided tape to secure the bottom of the GPS antenna to its new
location. Do not cover the antenna with tape.

9 Replace the cover on the station and thread the cable through the opening at

the base of the cover.

10 Turn on the Network Extender to allow the detection of available GPS satellite

signals. Note, four GPS satellites (strong signals) are needed to acquire a GPS
location fix and may take up to 60 minutes.

11 If a GPS fix still cannot be acquired, check the GPS signal in the Admin

Website’s GPS status page. If the device does not have 4 or more strong GPS
satellite signals, place the GPS antenna in another location to receive a
stronger signal. In some scenarios, an outdoor GPS antenna (not included)
may be needed if adequate GPS signal is not availab le indoo rs.

Chapter 5

Troubleshooting

This section provides some troubleshooting tips for the Network Extender.

Power/Status Indicator Light is Not Turning On

• Make sure the power adapter is securely connected to a working power outlet.

• Make sure the power adapter’s connector is securely inserted into the DC 12V

port on the back of the Network Extender.

Network Extender has not acquired a GPS fix even after an hour

• If possible, move the Network Extender to a new location with fewer

surrounding obstructions. The new location should be in an open area and
closer to a window.

• Unplug the power adapter for 10 seconds and then plug it back in again. This

allows the Network Extender to re-initiate its startup se qu ence during which
it detects the Ethernet connection, GPS signal, and communication with the
Verizon Wireless network.

• If the GPS signal is not detected even in the new location, install the GPS

extension cable and reposition the GPS antenna, as shown in the Configuring
Your Device.

• The GPS antenna must stay connected to the Network Extender at all times

for operation.

Unable to Place Call Using Network Extender

• Verify the device is powered on and in service.

• Check that the router is communicating properly with your ISP. The Internet

activity LED on your router and the back of the Network Extender should be
blinking.

• Check that advanced calling is in use as found in the Network Extender

Setup.

• Verify that your phone is connected to the Network Extender by dialing #48.

Chapter 5 Troubleshooting

Alarm

Description

Troubleshooting

Power/Status LED Indicator is Blinking

A blue blinking LED indicates the Network Extender is not operational. It may be
starting up, attempting to connect to the Verizon Wireless Network or waiting for
GPS. Please check the LCD display and status page on the Admin Website to
narrow the problem.

Confirm your Network Extender was activ ated at the time of purchase. If your
Network Extender has not already been activ ated, ca ll Ve rizon Wirele ss Cu stom er
Service at [phone] or *611 from your Verizon Wireless mobile phone and
select the option for technical support.

Before contacting Verizon Wireless Customer Service, confirm the following:

• Is the Internet activity LED on your router blinking?

If it is not, then there may be a communication problem between your
Network Extender and the router. Check that the router is communicating
properly with your ISP. For further router troubleshooting tips, please review
either the router manufacturer's printed or online documentation.

• Does the GPS icon show the GPS is tracking one or more satellites?

If not, the Network Extender may not be receiving a GPS signal. Move the
GPS antenna as shown in the Configuring Your Device chapter.

The following alarms may appear on the display of the Network Extender. These
alarms will be displayed on the Network Extender Admin website (local).
