Connect the USB Extension Cable - Verizon Wireless UMW190
While use of the cable is not required in a CDMA coverage area, it may be utilized to provide increased performance under certain operating conditions (e.g., poor signal strength) and / or free up space around the computer's USB port.
In a GSM network coverage area, the cable must be used to provide reliable and increased performance.
Insert the single end of the Y-shaped cable into the UMW190 Modem.
Connect one or both of the USB Y-cable's connectors to the computer.
Connecting both USB connectors will provide increased power to the device, which may improve Radio Frequency (RF) performance.
