SETUP  MODE  PASSWORD  PROTECTION 
ACCESS

The MPM4 is equipped with a lockout function to prohibit 
unauthorized  modification  of  the  system  setup 
parameters.    Setup  Mode  is  accessible  to  the  system 
installer  in  new  units  and  the  Mode  Select  button  is 
illuminated to indicate this condition. A default password 
sequence (Zone 1, Zone 2, Zone 3, Zone 4) is encoded in 
the unit, but only becomes effective when the Mode Select 
button  is  held  in  for  four  seconds,  which  activates  the 
password  and  denies  access  to  the  Setup  mode.    The 
Mode  Select  light  goes  out  and  only  Normal  Mode  is 
available to the system operator.

Unlocking Setup Mode

To gain access to Setup Mode, press and hold the Mode 
Select  button  until  the  In  and  Zone  buttons  on  the  left 
illuminate.   Enter the password code sequence on them 
and then press and release the Mode Select button.   The 
Routing display will blink once if the correct code sequence 
has  been  entered,  and  the  Mode  Select  button  will 
illuminate  to  indicate  that  the  Setup  Mode  functions  are 
unlocked.  Entering an incorrect code will return the MPM4 
to Normal Mode.

Changing the Password

Custom passwords can be created by the system installer 
to protect the settings of the Setup Mode.  Passwords can 
be  from  0  to  8  characters  long  and  are  created  from 
pushing a pattern of the In and Zone buttons.

To  change  the  password,  simultaneously  push  and 
release the Zone 1, Zone 4 and Mode Select buttons.  The 
In and Zone buttons on the left all illuminate.   Push the 
desired  sequence  of  buttons  and  then  activate  it  by 
pushing the Mode Select button, which will begin flashing.  
The password sequence must then be correctly repeated, 
followed by pushing the Mode Select button to validate it.   
Successful reentry will cause the Routing display to flash 
twice and the Mode Select button to be fully illuminated.   
An incorrect verification sequence will cause the MPM4 to 
exit  the  Password  Change  mode.    Setup  Mode  is  still 
accessible  and  the  previous  valid  password  is  still 
recognized by the MPM4.

In the event Setup Mode adjustments are required and the 
password  is  unknown,  it  is  possible  to  reset  the  MPM4 
back to the default password.  Disconnect the power from 
the unit and locate the two-pin shorting jumper on the back 
of the display circuit board behind the LED matrix inside 
the MPM4.  Remove the jumper plug and push it onto the 
Password Reset pins #2 and #3 located on the three-pin 
reset header to the left.  (See diagram.) 

Apply power, wait for the turn on sequence to complete and 
remove power.  Return the two-pin jumper plug to its storage 
pins.  The password is now reset to (Zone 1, Zone 2, Zone 3, 
Zone 4) and Setup Mode is automatically unlocked.
