Circa Mid 1970's to Late 1970's

Compatible TVs:

• Zenith Chromacolor II TVs (1976–1980s)
• Example models:
• System 3 (1978–1982): E.g., Zenith SC-6000, SC-6100.
• Space Command 400/500 Series: E.g., models ending in "-75", "-76", "-79".
• Mechanical Tuner TVs:
• Earlier 1970s Zeniths with motorized channel selectors (not electronic tuning).

Functions Controlled:

• Channel Up/Down (VHF/UHF)
• Volume Up/Down
• Power On/Off (if TV supported it)

3. Key Technical Details:

• Technology: Ultrasonic (not infrared).
• Pressing buttons struck tuned aluminum rods (~41 kHz for channel up, ~38 kHz for channel down).
• Power: No batteries—mechanical energy only.
• Interference Issues:
• Could be triggered by jingling keys, dog barks, or even squeaky doors.

4. How to Verify Compatibility:

1. Check Your TV's Manual: Look for "Space Command Ultrasonic" or "S-97XXX" in the specs.
2. TV Production Date: If your Zenith TV is 1970–1980, it likely works.
3. Test the remote by pointing it at the TV and press buttons—if you hear a faint "ping", it’s ultrasonic.
