3.3  CODING THE TRANSMITTER AND RECEIVER UNITS 
In order to make the receiver execute a function, the code in the handheld unit, the transmitter, must be 
transmitted to the receiver and correspond with the code stored in the receiver. 
The DE212 system has 65536 different codes available. Each code and serial number is logged by the producer, 
and a code is only used once. The transmitter is coded from the factory, while the receiver must be coded by the 
user before starting operation as follows: 
 
Press the yellow CODE button on the receiver front panel. Simultaneously press the red transmitter STOP button. 
After about three seconds, the green ON-LED will flash three times, indicating that the code is stored. The 
system is now ready to operate. The code is stored in the receiver even if the power is turned off. 
 
Erasing the code: 
The stored code in the receiver is erased by pressing first the Deadman button on the transmitter then the 
CODE-button in the receiver, after some seconds, the green ON flashes 5 times, and the code is erased. To 
maintain normal operation again, the receiver must be re-coded.
