Setup
Follow these steps to correctly connect your JVC HR-J643U VCR to your television and power supply.
1. Connecting to a Television
Your VCR can be connected to a television using either Audio/Video (RCA) cables or an RF coaxial cable.

Connect the white (left audio) and red (right audio) output jacks on the VCR to the corresponding input jacks on your TV.
- RF Coaxial Connection: If your TV does not have RCA input jacks, use an RF coaxial cable. Connect the RF OUT jack on the VCR to the antenna input jack on your TV. You may need to tune your TV to channel 3 or 4 to receive the VCR signal.
2. Power Connection
Once all audio/video connections are made, plug the VCR's power cord into a standard AC electrical outlet.
3. Initial Setup
- Clock Setting: Upon first power-up, you may need to set the clock. Refer to the on-screen display (OSD) menu for instructions, typically accessed via the remote control.
