the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that the interference will not occur in a particular installation. If this equipment
does cause unacceptable interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures -- reorient or relocate the receiving
antenna; increase the separation between equipment and receiver; or connect the into an
outlet on a circuit different from that to which the receiver is connected.

FCC WARNING
To assure continued FCC compliance, the user must use a grounded power supply cord and
the provided shielded video interface cable with bonded ferrite cores. Also, any unauthorized

Remark：

(1)：“x” – Indicates which inputs are available for PIP and POP modes.

(2)：For AV1 and AV2, S-Video has priority. If a signal is connected to AV1 S-Video by itself or

signals are connected to AV1 S-Video and AV1 Video simultaneously, then S-Video will

be the only choice for AV1. If a signal is connected to AV1 Video only, then Video will be

the only choice for AV1. The same input priority scheme applies to AV2.
