5. Limitations Caution!

5.1. PC Environment Limitations

The ARCP-990, ARHP-990, and ARVP-10 are compatible with the Windows 7
(32-bit or 64-bit), Windows 8.1 (32-bit or 64-bit), or Windows 10 (32-bit or
64-bit). Use the operating systems described above for both the host and
remote stations.
Applicable operating systems are subject to change without notice due to the
end of the technical support by Microsoft Corporation or change of the product
specifications.
For KNS operations, it is necessary to set and change the open broadband
router ports, Windows firewall functions, and comprehensive security software.
Furthermore, it is the customer's responsibility to handle security when using
this system. If you do not have confidence in the settings, we recommended
you stop using the system.

5.2. Network Environment Limitations

During KNS operations via the Internet, it is necessary to set the global IP
address on the host station. For your global IP address, consult your contracted
provider.
Only registered people can access the host station using their ID and password.
Make sure that the ID and password settings cannot be guessed easily by
unauthorized people.
On this system, signals are exchanged via the network. Consequently, smooth
operations may be disabled compared to normal transceiver operations, as
delays (during analog/digital conversions) and data loss (which is greatly
dependent on traffic) are unavoidable. This is the principle operation of the
system.
Examples are cited below.
Audio may break up, meter deflection may not be smooth, standby time may be
delayed (in particular, it is not suitable for contests or quick operations such as
pile-ups). VFO variability may not be smooth, audio may differ from the actual
transceiver audio and digital mode communications such as image
communications with SSTV and AFSK, PSK-31, etc., may be disabled, etc.
Broadband is recommended for the Internet line used. As a benchmark, use a
minimum of 1 Mbps. The speed of analog modems that use telephone lines will
greatly reduce sound quality, and may destabilize control, and so cannot be
used.
