# Relevant O4A codes

00079 - SIRC (A:0x00 C:0x15)

# Procedure for programming a key magic code

Hold Magic until LED blinks

Select device (has to roughly match the real world device - use DVD) - LED should blink twice (if not, the device code was rejected)

Enter 994 (two blinks)

Press magic

Enter key magic code

Press the button to assign it to. LED will blink twice.

# Remote Reset

Hold Magic until LED blinks twice

Enter 981

Wait until TV blinks 4 times

# Observations

Key Magic functions manually added will persist until they are replaced with different key magic or the remtoe is reset. *Simply entering a new device code will not replace the key magic functions*

The device that's programmed has an effect on the key magic function that's added.  Examples:
