Try to think of your setup as two different signal paths. Signal path A is the VCR and signal path B is the TV. To record a channel you will press the âAâ button on the A/B switch and tune the A-side DTV converter box to the channel you want to record. Then set your VCR to record on channel 3 and select a record time.After setting your VCR to record press the âBâ button on the A/B switch to watch TV. You can freely turn channels on the B-side DTV converter box while recording on side A. Thatâs why I recommend using two different DTV converter boxes.ry to think of your setup as two different signal paths. Signal path A is the VCR and signal path B is the TV.

The Precambrian or Pre-Cambrian; sometimes abbreviated pÐ is the largest span of time in Earth's history before the current Phanerozoic Eon, and is a Supereon divided into several eons of the geologic time scale.he Precambrian Supereon is divided into three eons: the Hadean (4500-3950 Ma), Archean (4000-2500 Ma) and Proterozoic (2500-541.0 Â± 1.0 Ma). See Timetable of the Precambrian. 1  Proterozoic: this eon refers to the time from the lower Cambrian boundary, 541.0 Â± 1.0 Ma, back through 2500 Ma.
