Do you have a better link to the BT7 output settings? I have a few questions from the details provided on this site:

Usage Tips:

BT-7 features six selectable output settings:
(1) 111.11 Hz., (2) 1 sec. ON / 1 sec. OFF and (3) 7.83 Hz. all at 550 microseconds pulse-width. Settings - (4) 111 Hz, (5) 1 sec. ON / 1 sec. OFF (6) 7.83 Hz. at 220 microseconds pulse width setting.
Feel free to experiment with all of these settings. There is no data to indicate that one setting is more effective than any other. Numerous harmonic frequencies make up the basic waveform and these are present in all of the six settings.

Settings 2 & 3 and 5 & 6 may be more relaxing, whereas the 111 Hz. may be more energizing. Settings 2 and 5 represent the DELTA brainwave frequency, normally associated with deep sleep and release of deeply embedded stress patterns. The 7.83 setting ( no. 3 and 6 ) represents the middle ALPHA brainwave frequency and is associated with a relaxed, but very focused mental state.

Also, creativity, superlearning, memory improvement, intuitive insights and more. BT-7 may be used any time of day. It is important to use the BT-7 each day for 2 to 3 weeks in order to achieve the maximum benefits.

There is no need to repeat the entire 2 to 3 weeks if you happen to skip a day or two. Following the initial series of sessions, BT-7 may be used on occasion as desired to maintain the initial improvements. For example, memory improvements may last up to 1 year before additional sessions are necessary.
Other gains may be more temporary and require more frequent reinforcement.
Individual results will vary.

Below are my Q's:

I'm not clear on the difference between 2 and 5. Is it simply 111.11Hz vs. 111Hz?

Also - 550 microseconds vs. 220 pulse-width. Both are "Earth"/ALPHA. I read that Beck preferred 3 also. Am I correct in assuming that 220 is simply faster?

Lastly - any insight on whether there's an issue using two different setting for 20 minutes in one day's time (eg., one in AM, another PM)? What about switching from one setting to another within a 20 minute session? What exactly is the concern regarding using for longer than 20 minutes? Any clue? Diminished efficacy, maybe?
