OK - Now I understand what is happening here.  Cool !
However, I do like the entire phone to be "off" before I go
to bed.
I recently discovered this alternate method to do an
OFF-event.

Observe that in the lower-left corner is a RED Phone button
(this button also has a tiny unexplained "POWER-OFF" symbol
on it)

While the 6700 is still ON, Press and Hold the RED Phone
button until you hear a low-pitched "DONG-NG-NG" sound.

Next, at the top of the screen both the Internet symbol
(displays either '1X' or 'EV'), and the Signal Strength
symbol will now also have a tiny "X" next to each of them.

NOW, the 6700 will not receive or originate any calls, this
seems to be a key-stroked similarity  to the Flight Mode,
and if your phone is (most likely) on Battery Power, leaving
the phone in this condition, depending upon your customized
Battery Power settings,  will cause the 6700 to eventually
completely shut down, and Power-OFF.

After doing that, to initiate another Power-On, you must
press the top-mounted Power Button until the screen light
turns-ON; at this time you can use the PDA functions.
Next, do  Press-and-Hold that same RED Phone button until
you hear a short "upbeat-sound".
These actions will then restore the 6700 back to a full
PHONE Power-On condition, and ready to again resume
receiving and originating calls.

This PPC-6700 is a pure geek's delight.

This 67-year-old non-geek absolutely LOVES this phone!
The Microsoft Mobile op system does not seem to be "quirky"
as the Palm OS often is.
The PPC-6700 now allows me to carry only ONE device,
instead of a "regular" cell phone, and PDA.
While my wife & I are shopping at the Mall, I can sit down
somewhere and "play"  the free Wi-Fi and Internet!!
Meanwhile she can still contact me with her Sprint PCS cell
phone.
Fantastic!!!   ---Juan
