Before connecting to the PC
The process of connecting the USB cable (third party)
between the transceiver and a PC may differ accord-
ing to your OS.
See the “Driver installation” on pgs. 4 to 11 for details.
• After the driver installation is completed, the USB
cable can be connected regardless of the OS.
• The USB driver installation is required for each unit,
because of the COM port number difference.
Important
• Audio from the USB port may cut out or audio con-
trol with the PC software may get late because of
the PC performance (including OS, environment,
etc.)
• Audio from the USB port may cut out when the CPU
load increases.
• The audio device settings of OS may be changed
when the transceiver is connected to the PC.
• Icom is not responsible for proper operation when
connecting the transceiver and the PC through an
USB hub.
For IC-PCR1500/IC-PCR2500 user
• USB driver on the supplied CD
The file that is included on the supplied CD with
the IC-PCR1500/IC-PCR2500 is the same as the
download file from Icom HP. So, the USB driver in-
stallation can also be performed with the supplied
CD.
• USB driver uninstallation
If the USB driver uninstallation is performed, the
connected unit (when the USB driver is installed) or
IC-PCR1500/IC-PCR2500 cannot be used.
• USB driver re-installation
The USB driver installation is required for each
unit, because of the COM port number difference.
See the IC-PCR1500/IC-PCR2500 instruction man-
ual when installing the USB driver with the supplied
CD.
