3. When finished, the newly selected channel will appear on the Status LED via a series
of green and red blinks again.
4. Exit the channel programming by turning off the transmitter power.
5. Make sure the receiver channel is set identical to the transmitter.
See Section 4.2.1
on page 34
and
Section 4.2.3 on page 38
on how to change the receiver channel.
6. Please note that when the CHANNEL dipswitch inside the transmitter is changed, the
priority will revert back to the new channel set on the CHANNEL dipswitch.
7. Please note that when the channel is set beyond channel 62 via PB1 and PB2 (i.e.,
channel 63, 68, 88, etc.), the system will recognize it as channel 62.
4.1.4
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 system 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 1, 2, and 3.
NOTE:
To power-cycle the transmitter, you must first remove, 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).
