EXAMPLE 4 
 
To specify a new "PS" lock password, after the old password was disabled (e.g. after three failed attempts to
change the "PS" password): use the master phone code. 
CAUTION: THIS TEST SHOULD BE PERFORMED ONLY IF THE CORRECT MASTER PHONE CODE FOR
THE INDIVIDUAL ME USED IS DEFINITELY AVAILABLE! Otherwise the module used will be rendered use-
less until the correct master phone code is entered!: 
Alternatively, without giving a new password: 
AT+CPWD="PS","12345678","1111" 
where 12345678 is the Master Phone Code and
1111 is the new password. You may also use <new
password> to restore the former disabled pass-
word. 
OK 
AT+CPWD="PS","12345678" 
(where 12345678 is the Master Phone Code). Deac-
tivates the present phone lock. 
OK
