Jakeman, please don't take this the wrong way, just curious because I have just bought one of these myself--

Here are the steps on page 16.

Programming the Master Power Key
1. Press and hold the P key for 3 seconds until the
LED indicator turns on and stays on.
2. Release the P key.
3. Press the device key you want to add to the
power macro.
4. Press the CH + key and the LED blinks.
5. The LED stays on.
6. Follow steps 3 and 4 to add more devices to
Master Power.
7. When all devices are added Press VOL + key to
enable Master Power.
8. Press the P key to complete the process.

I am just curious, after you enter the first device and press the CH+ key, the LED blinks and stays on, correct?
Then, when you press the next device key to add the second device and press the CH + key, the LED blinks again and then stays on, right?
The LED stays on until you press VOL + then P, when it goes off.

Just checking for the proper feedback from the device during the programming process.
