4.1.3 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 START position to begin operation, you first enter a 4-digit security
code in order to proceed further. When this 4-digit security code is entered correctly, a green light will
appear on the Status LED. Please refer to the instructions below on how to program the 4-digit security
code.
a.
Release E-Stop, then press and hold PB1, PB2, PB3 and PB4 (all at once), and then rotate
the power key to START position.
b.
A constant orange light will appear on the Status LED telling you that you are in the security
code programming mode.
c.
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 blink orange slowly, telling you that the 4 digits entered is 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 again
(programming completed). If any mistake is made during this process, or if a red light is
shown 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 again.
*NOTE: To power-cycle the transmitter, you must first remove, then reinstall the batteries. Simply
turning the power switch off, 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).

distributor for further assistance.
