The newest P3 Owner's manual revision (A5) covers this: K3 MCU LD Error If you attempt to download firmware to the K3 while the P3 is turned on, the K3 may become unresponsive in bootstrap mode (MCU LD displayed on the K3’s LCD). Clear the condition as follows: Turn the P3 off. If the P3 is configured to turn on automatically when power is applied to the K3, disconnect power from the P3’s rear panel. It’s important that the P3 remain off throughout the procedure. Disconnect power from the K3’s rear panel. Exit the K3 Utility program at your computer. Reconnect power to the K3’s rear panel and turn the K3 on. Be sure the P3 does not come on with the K3. If it did, repeat the procedure from the beginning and be sure to unplug the P3’s power cable. It won’t work to turn the P3 off once it has turned on. Restart the K3 Utility at your computer, and reload the firmware.
