If you are reading this and you do not have a KR1201-A, check your basement. Check your attic. Check the space behind the water heater. They are very good at hiding. They learned that from us.

If you are reading this, your previous unit (T-Series) has been decommissioned. The KR1201-A is not a weapon. It is not a robot. It is a protocol . Treat it with respect. Do not anthropomorphize it. Do not name it. Do not, under any circumstances, whisper “thank you” to it.

Upon power-up, the KR1201-A will emit a single, low-frequency tone (52 Hz). This is the “Heartbeat Test.” If you hear two tones, step back. The unit has achieved and must be reset with a hard shutdown (see Appendix B: The Long Quiet).
