Manual

5.9 Connecting Accessories (Optional)
The optional UPS battery guarantees extended power, in case of AC main power
loss. To install the UPS battery accessory (optional) from T-Mobile, plug in the power
adapter and then connect the other end to the T-Mobile High-Speed Internet
Gateway through the DC output cable.
5.10 Repositioning the T-Mobile High-Speed
Internet Gateway
The T-Mobile High-Speed Internet Gateway can display up to 5 bars to identify signal
strength. Use the device’s LCD screen to check the 5G signal strength.
Do the following if the LCD activity described in section 5.6 indicates that you should
reposition the T-Mobile High-Speed Internet Gateway for a better signal:
Procedure 5 Reposition the T-Mobile High-Speed Internet Gateway
1 Power off the T-Mobile High-Speed Internet Gateway and disconnect it from the electrical
outlet.
2 Move the T-Mobile High-Speed Internet Gateway to a different location.
3 Connect the T-Mobile High-Speed Internet Gateway to an electrical outlet at the new location
and power it on.
4 Check the LCD as described in section 5.6 and follow the actions indicated in the section.
If the LCD continues to either show an X or shows the “LANGUAGES” screen after the on
boarding process, you might need to connect the T-Mobile High-Speed Internet Gateway to
a Gigabit Ethernet LAN because 4G/LTE or 5G service cannot be received at this time.
Note — Once you have a good signal, it is recommended that
you do not reposition the device. If the position changes, you
may need to check the signal strength again.
Note — You might need to repeat this cycle several times before finding
the final location for the T-Mobile High-Speed Internet Gateway
