If You Suspect a Problem

If you notice a symptom that leads you to suspect the
video network station may be broken, please check the
following items before contacting your Sony Service
Center.

Remedy
Use the following procedure to
check for unique IP address
assignments:
1 Enter the following at an MS-
DOS prompt (command
prompt):
ping <host name or
IP address of video
network station>
2 The cause of the problem
can be determined from the
response received:
• bytes=32 time=2ms ...
The IP address has already
been assigned. Please
obtain and set another IP
address.
• destination host
unreachable
The video network station
is not on a reachable
network node. Please
obtain and set another IP
address.
• request timed out
The IP address has not
been assigned to any
users. It can be assigned to
the video network station.
The "arp" command cannot be
used in Windows 95 when the
ARP table is empty. Enter "arp-
a" at an MS-DOS prompt
(command prompt) to display
the ARP table contents. If it is
empty, execute a "ping"
command to an existing host
on the network, and then
download an IP address to the
video network station with the
"arp" command.
Confirm that the supplied AC
adapter is connected.

Lithium Battery Replacement

The lithium battery lasts about two years with normal
use.* When the battery is depleted, the data and time
settings are lost. Contact your Sony Service Center to
have the battery replaced (for a charge).
*Presuming the power is normally kept on. If the
power is regularly turned off, battery life can be
expected to be about one year. Actual battery life
depends on the operating conditions.
Remedy
Confirm that the network cable
is connected correctly by the
following procedure:
1 Execute a "ping" command
to an existing host on the
network.
2 If a response such as
"...bytes=32 time=2ms" is
received, the cables are
connected properly.
Contact your system
administrator.
Check whether a default router
setting is required.
Prepare a script to run on the
Web server and replay images
sent from the video network
station to the Internet.
If several clients attempt to
access the same image at the
same time, memory limitations
may degrade server
throughput. Try reducing the
number of clients.
Change the computer display
setting to a minimum of 65,000
colors (16 bits). Poor image
quality will result if the display
is set to 256 colors or less.
