Connecting an A/B Switch

and a Signal Splitter

You can record a scrambled channel and watch an unscrambled one using a high-isola- tion A/B switch (such as Cat. No. 15-1249, not supplied) and a hybrid splitter/combiner (such as Cat. No. 15-1141, not supplied).

Notes:

This connection requires up to four addi- tional 75-ohm coaxial cables (such as Cat. No. 15-1529, not supplied).

You cannot record scrambled channels without using a cable box.

You can record a scrambled channel while you watch an unscrambled channel.

6.Connect another 75-ohm cable between the A/B switch’s output terminal and your TV’s VHF/UHF input terminal.

Note: If your TV has separate VHF/UHF termi- nals, connect the cable to the TV’s VHF termi- nal only.

SETTING THE OUTPUT

CHANNEL SWITCH

Set OUTPUT CHANNEL (on the back of the VCR) to 3 or 4, whichever is not an active chan- nel in your area.

When you use the VCR, it sends its output sig- nals to the TV on the channel you selected.

Note: OUTPUT CHANNEL has no effect on the TV when the VCR is off or if you are using a TV that has separate audio/video input jacks and you set the TV to the video mode.

CONNECTING POWER

When you complete all other connections, plug the VCR’s power cord into a standard AC out- let. –:- - flashes on the display.
