5.1 USB Port Connectivity Limitations

If the PC and TS-990S are connected via a USB cable, audio transmissions can be
transmitted using the USB audio function. In principle, however, there is a delay with
USB audio signals. Additionally, sound may be delayed or lost depending on the PC
performance and load status. As such, do not perform operations for which delays are
likely to be a problem (such as contests or communications requiring quick responses).
Also, when connected with a USB cable, alert sounds from other software or audio from
music or videos may not play over the computer speakers.
Furthermore, when the DATA VOX function of the transceiver is "ON" and the
computer and transceiver are connected with a USB cable, the transceiver may
send sounds emitted by the computer. To avoid unintended transmissions when
the computer and transceiver are left connected via USB, set the DATA VOX
function to "OFF."
Depending on the combination of OS, PC and sound functions, the USB audio function
may not operate correctly. JVC KENWOOD does not offer support for customer
computers.
