As mentioned at the beginning of this section, here is the procedure to follow if you don’t get a 
steady yellow light on power up
.  The absence of the yellow light means that for any reason, 
the unit already has one or more codes in memory.  You must erase these other codes to be 

certain that the unit will operate only on the codes you plan to enter.  Follow the steps shown 
below. 
 

Press the “Hard Code” button on the CPU board for one second. 

 

Confirm slow flashing yellow LED  

 

Press the Bell key (yellow flashing stops).  Confirm two red flashes 

 

Press the “Prgm Code” button on the CPU board for one second. 

 

Confirm fast flashing yellow LED  

 

Enter 8-8 followed by the Bell key (or wait 5 seconds).  Confirm two red flashes 

 

Extinguish the fast yellow flashing LED by pressing the Bell Key or waiting 30 seconds 

This procedure has erased any Hard code that was present (see Section 4.1) and all user codes.  
The yellow LED will usually come on steadily.  If it doesn’t, it means that the unit has a previous 

Program code in memory and this is no problem as you will be overwriting the old Program code.  
Return to the beginning of this section for keypad changeable programming. 
 
4.2.1  CHANGING THE USER AND PROGRAM CODE FROM THE KEYPAD 
This is the day to day procedure that should be taught to the end user.  Normally the end user 

will not access the CPU board.  Everything should be done from the keypad.  To change the User 
code: 
 

Enter program code, followed by the Bell Key, note rapid yellow flashing LED (program 

 mode) 
 

Enter prefix 0-1 followed immediately by a new 2-7 digit User code 

 

Wait 5 seconds 

 

Note two red LED flashes for confirmation, note rapid yellow flashing LED returns 

 

Press Bell key to terminate program mode or wait 30 seconds 

 

Re-enter new User code (door should open) 

The program code should need changing much less often.  To do it: 
 

Enter old program code followed by the Bell Key, note rapid yellow flashing LED 

 (program 

mode) 

 

Enter prefix 0-0 followed immediately by a 5-7 digit new Program code 

 

Wait 5 seconds 

 

Note two red LED flashes for confirmation, note rapid yellow flashing LED returns 

 

Press Bell key to terminate program mode or wait 30 seconds 

 

Re-enter new Program code followed by the Bell Key (to test it), note rapid yellow 

 

flashing LED returns 

 

Press Bell key to terminate program mode or wait 30 seconds 

The logic behind this procedure is as follows.  All programming for the DK-26 starts with putting 
the unit into program mode (except entering the single Hard code).  The unit is put into program 

mode by either pressing the “Prgm Code” button on the CPU board or entering a valid program 
code.  When you enter a program code, however, you have to terminate the sequence with 
the Bell Key
.  This is for a little extra security.  An unauthorized person who came across a 
copy of the Program code might not know he had to press the Bell key after entering it.  The 
prefix 0-0 causes the code which follows to be stored as the Program code.  The prefix 0-1 

causes the code to be stored as a user code. 
 
4.2.2  ADDING MULTIPLE USER CODES 
The DK-26 has memory locations for up to 59 User codes.  This allows separate codes for 
individuals or groups which is a benefit because when one code is changed (usually owing to a 
security worry), the people who use the other codes don’t have to learn a new code.  To
