Connecting the 4250HD
To connect your 4250HD to your entertainment devices, complete these steps.
Identify the additional devices you will
connect to the 4250HD and TV. See
pages 13 through 18 and the related
user’s guides for more information.
Do not turn on the 4250HD or TV yet.
It may take several minutes for the 4250HD to receive the latest software, programming, and
service information. Wait until one of the following appears on the front panel of the 4250HD
to indicate that the update is complete:
• Current time • Four dashes (- - - -)
Note: If four dashes appear, your 4250HD is not authorized. Call your cable service provider.
Determine if your TV is HD or SD and
whether it is wide screen (16:9) or
standard screen (4:3). See page 20
for more information.
Make the connections for your TV and VCR as follows:
• If you are using an HDTV, see page 8 for a description of the connectors, and see the end
of this guide for connection diagrams.
• If you are using an SDTV, see page 10 for a description of the connectors, and see the end
of this guide for connection diagrams.
Plug the 4250HD and the TV into an AC power source that is not controlled by a switch.
Important: To protect the set-top from power surge damage, ground (earth) your cable
product to provide some protection against voltage surges and built-up static charges.
To avoid these voltage surges that can be caused by lightning storms and power outages,
plug the set-top into a surge protector to reduce the risk of damage.
