Quick steps (RF / aerial/coax connection)

1. Find the RF socket on the Einstein — it has an RF / TV (UHF) phono/coax connector on the right-hand side of the case.
2. Use a coaxial lead (TV aerial/antenna lead) from the Einstein’s RF socket to your TV’s “Antenna / Aerial / RF IN” socket. If the plug types differ (e.g. the computer uses a phono-to-coax adapter), use an appropriate adapter or an “RF computer → TV coax” lead (these are sold for Tatung Einsteins).
3. Switch the TV input to the aerial/antenna (not HDMI/AV).
4. Tune the TV to the correct channel: the Einstein outputs a UHF RF TV signal — tune the TV to the UHF channel the modulator uses (many vintage UK microcomputers used a UHF channel; the Einstein’s RF/UHF characteristics are documented). If your TV has manual tuning, you may need to manually set the channel or frequency.
5. Power on the Einstein and you should see the boot screen. Adjust the TV fine-tune if the picture is snowy or drifting.

Troubleshooting

• No picture / noisy picture: confirm cable firmly on both ends, TV set to antenna mode, and TV tuned to the correct UHF channel/frequency. Try manual tuning if auto-scan misses it.
• Different connectors: modern TVs sometimes use IEC “coax” or F-type — adapters are readily available. If the Einstein uses a small phono RF socket, a little adapter lead (or dedicated Tatung RF lead) will fix it.
• Modern digital TVs: many modern sets expect digital broadcast signals; they may ignore an analog RF carrier or label it differently. If your TV will not accept the analog RF at all, try a different display (an older TV) or use an alternative video output (see below).

Better-quality alternatives (recommended)

• Composite video (if your Einstein model provides it): far better than RF. Use a composite lead to a TV’s AV input or a composite→SCART adapter for UK sets. The Einstein has composite and RGB outputs on some models/expansions.
• RGB / SCART: for the best picture on a CRT TV or via a SCART→HDMI/SCART→OSS C box, use an RGB SCART cable (community guides / cables exist for Einstein → SCART). You’ll get a much sharper, stable image than RF
