these circumstances: a) the videotape is dubbed; b) the

signal reception is weak; or c)

the signal reception is

nonstandard (- p. 34).

connections (- p. 22).

• Confirm your modem’s operation.

• Ensure your IP address is set up correctly.

No network connection

• If using a wired network connection, check to ensure the

LAN cables are connected properly (- p. 22).

• Ensure the modem and router power cords are plugged

in and the devices are operating properly.

• Ensure your IP address is set up correctly. See Section

(- “Setting up the Network”).

er operation of other network

connected devices.

Network Setup fails (Auto)

• Check to ensure the LAN cables are connected properly

(- p. 22).

• DHCP is not enabled on the r outer, or no router is

present. Refer to your router’s documentation for

instructions on enabling DHCP. If you do not have a

modem or contact your ISP for Internet service issues.

Network Setup fails (Manual)

• Ensure the TV IP address is not the same as any other

device on the network.

Example: IP address 192.168.0.100 and IP address

192.168.0.101 are different addresses on the same

network.

• Make sure the TV IP address is on the same subnet as

the networked PC.

Example of proper setup: The PC has IP address

192.168.0.100 with Subnet mask

255.255.255.0, the TV

has IP address 192.168.0.101 with Subnet mask

255.255.255.0; both are on same subnet.

Example of improper setup: The PC has IP address

192.168.1.100 with Subnet mask 255.255.255.0, the TV

has IP address 192.168.0.101 with Subnet mask

255.255.253.0; they are on different sub-nets.

Unstable network connection

the LAN cables, and then reconnect them.

• When using a wireless home-network connection:

– Remove AC power from the router and the television

for 30 seconds.

• Reconnect AC power to the router.

• Reconnect AC power to the television and p

ower it

ON. After 2 minutes, check connection stability.

–Connect with LAN cables, if possible, and check

connection stability.

check connection stability.

• The LAN cables, if used, are not connected properly (-

p. 22).

both the DMS and TV are using the same network type

(DHCP/manual) and have compatible network settings.

more than 32 sharing devices at one time.

• The DMS is not turned ON.
