In the Motorola Microtac 550 series, we have recently discovered
the test mode entry has been changed.

You do NOT 'short the battery' in the EE series phones.

Everything, including 'deep programming' is done from the keypad.

For access to NAM programming use this:

          FCN 0000000000000 RCL

That is the function key, thirteen zeros and recall. Now it may 
actually be FCN 0 (your security code twice) and recall. The code
on the phone I tested was 000000 (six zeros). So if 'thirteeen
zeros' does not work try zero followed by your security code twice
and then RCL. 

For access to the deeper stuff such as 32# to zero out the registers,
and 55# to program the NAM (the usual stuff as described in the
other Motorola cellular files in this directory) use this:

         FCN 00 * * T E S T M O D E STO

That is FCN two zeros, two asterisks, then spell out 'TESTMODE'
using the keypad followed by STO. 'TESTMODE' is 83786633 ...

That should get the phone to wake up in test mode with the 
alternating display of numbers. Pressing # will get you the US '
prompt. 01# kicks the phone back into regular mode. You can do
all the XX# commands described in other files at that point, although
some of the XX# commands documented elsewhere seem to be different
in the Microtac 550 EE series phones. 32# will do its job however,
as will 55#. As usual, if you do 32# wait until you get the prompt
back before exiting. 

Finally, in the documentation elsewhere, step 16 of programming
the NAM only discusses 7 bits to be set, however the EE series
phone definitly uses 8 bits here, although what each one does is
not known exactly at this point. 7 of them seem to resemble the
same place in older 'flip' phones, but not in the same order, etc.

Shorting the battery pins on the EE series phones definitly will
not work; the phone seems to ignore it. 

Motorola tech support seems pretty open and willing to talk about
whatever they know these days ... 800-331-6456.
