Optional 4-Digit Security Code
The 4-digit security code is an optional feature that can be programmed into the
transmitter to allow operation only to those who know the code. If this feature is desired,
set up as follows: Prior to rotating the transmitter power key switch to the START
position to begin operation, you must first enter a 4-digit security code in order to
proceed. When this 4-digit security code is entered correctly, a green light will appear
on the Status LED. See the instructions below on how to program the 4-digit security
code.
1. Release the E-Stop, and then press and hold PB1, PB2, PB3 and PB4 simultaneously.
Rotate the power key to the START position.
2. A solid orange light will appear on the Status LED indicating that you are in the
security code programming mode.
3. For newly purchased systems with the security code function deactivated (default
setting), press PB1 four times (1111) to activate the security code function. At this time
the Status LED on the transmitter will slowly blink orange, indicating that the 4 digits
entered are correct. Then select your own 4-digit security code by pressing PB1, PB2,
PB3 or PB4 on the transmitter (four presses randomly). At this time, fast orange blinks
are displayed on the Status LED, telling you to reconfirm the 4-digit security code you
have just entered. A green light will appear once you have re-entered the same 4-digit
security code (programming completed). If any mistake is made during this process,
or if a red light illuminates on the Status LED after you have re-entered the security
code (incorrect input), or even if you believe you have entered the correct code but the
transmitter fails to work properly, then you must reset the transmitter power (by power-
cycling the transmitter*) and then repeat steps a, b, and c.
NOTE:
*To power-cycle the transmitter, you must first remove and then reinstall the batteries.
Simply turning the power switch off and then on will NOT properly clear the memory. This
process must be used for any errors regarding proper transmitter operation (not just for security
code settings).
Steps:
Press and hold PB1 - PB4 and rotate the power key to the START position

4. If you wish to cancel the security code function, then repeat steps a, b, and c and
press PB1 four times as your new security code (security code function disabled).
5. If you do not remember the 4-digit security code, you must contact your dealer or
distributor for further assistance.
