Note that only profile 0 can be protected.
Setting S35 bit 6 in profile 0 will also protect the supervisor password. If this bit is
set, the supervisor password cannot be reset to the default ZyXEL by a modem hard-
ware reset (see chapter 18). Memorize your password well before setting this bit.
Resetting Profiles
After you have changed the user profile settings, you can reset all four user profiles
to factory preset values if you wish. This is done by holding the
ENTER key down on
a Supreme model while turning on the modem. On a non-LCD model, a reset is
done by holding the
DATA/VOICE switch down while turning on the modem. On an
internal card model, shorting the wire strapping TS2 and then turning on the power
will reset the modem. Remember that by resetting the modem, all of your user pro-
file settings are lost. Unless you have set S35 bit 6 of profile 0, this will also reset the
supervisor password to ZyXEL (see last section).
Note: The reset stated here is a total reset to factory state. If you get some-
where and cannot get back, this is the way to get to a known state.
The modem also does continuous self-testing after this reset (see
Chapter 18 for details). Turn off the power to stop the testing.
