Access Codes 
 
 
These are the access codes to the calibration and configuration menus. When an access 
code is required, pressing the following key sequence will provide access to the required 
menu. 
 
  Key #  Calibration    Configuration 
 
   1  RESET     LOW ALARM 
   2  LOW ALARM    TEST 
   3  NORMAL    RESET 
   4  TEST      HIGH ALARM 
   5  RESET     LOW ALARM 
 
If the access code is entered correctly, the first menu item is displayed.  
 
The audible alarm sounds briefly each time a keystroke has been entered. The access 
code must be entered within 40 seconds (approximately eight seconds per keystroke). If 
more than eight seconds elapses between keystrokes, the monitor returns to the normal 
operational mode. 
 
The audible alarm sounds, an error message (Err) flashes on the display, and the 
configuration menu is exited if an incorrect access code in entered.
