Compass Series HSPA USB Modem Installation Guide
Frequency band selection
Every GSM network operates on one set of frequency bands.
The Compass USB modem is designed to change frequency
bands automatically to obtain network service. You can also
change frequency bands manually from the
Network tab of the
User Options window (Tools > Options > Network).
Note: Unless your service provider specifies otherwise, it is recom-
mended that you use the Automatic setting.
Network selection
This option is set in the
Network pane of the User Options
window (
Tools > Options > Network > Network Selection Mode).
Depending on your location, you may be within the coverage
area of several networks. Your ability to obtain service on each
network depends on your account.
Your options for network selection are:
•
Automatic—The Compass USB modem automatically
selects a network based on your account and network
availability.
•
Manual—The Compass USB modem scans the area and
displays a list of detected GSM networks.
If you select a network on which you cannot obtain service,
the message, “Failed to register with network” appears.
Choose a different network.
