OPERATION IN CODE REGISTRATION MODE
(PROGRAMMING)
When the code registration switch is in the
SETI
or
SETII
position, the receiver enters the registration mode where it
stores the first received secret code in the EEPROM.
Two different secret codes can be stored with the switch in
the
SETI
and
,SETII
positions. Therefore, the user can use
two transmitters.
