215.3. Program LimitationsCW operations are possible, but keying using normal e-keys is not possible. Stringsentered using the keyboard are collated for transmit operations.5.4. Limitations if Using USB Audio FunctionsIf the PC and TS-590S are connected via a USB cable, audio transmissions can betransmitted using the USB audio function. In principle, however, there is a delay with USBaudio, so sound may be lost depending on the PC performance and load status. If using aUSB connection for transmitting audio on the host station, the delay due to network trafficto the remote station is also added, so the delay is further increased.If audio transmissions are connected via USB terminals, and if playing warning soundsfrom the OS or music and video on the PC, the sounds may not emit from the speakers.Furthermore, depending on the OS sound and properties, the transceiver DATA VOXfunction settings, and the modulation path, the audio may be modulated from thetransceiver, so be careful during PC operations and when playing these files.Depending on the combination of PC and sound functions, normal operations may bedisabled.Kenwood does not offer support for customer computers.We recommend using audio cables without using USB audio functions for KNS operations.(See "4.2. Connecting Audio Cables".)
