2. FUNCTION SETTINGS
2.1 TRANSMITTER
2.1.1 Channel Settings
Enter the transmitter function setting mode by moving the function dip-switch located inside the
battery compartment to the on position. Reinsert the two batteries and press PB1 to power up the
transmitter. At this point the Status LED will display a series of red, green, and orange blinks showing
the current software version. Then press and hold PB3 for up to 1.0 second to go into the transmitter
channel setting mode. At this point the Status LED will display a series of green and red blinks
showing the current system channel. A green blink represents the tens (+10) and a red blink
represents the units (+1). For example, one (1) green blink followed by five (5) red blinks is channel
15.
Now select a new channel by pressing PB1 and PB2 on the transmitter. Press PB1 to increment the
units (+1) and PB2 to increment the tens (+10). For example, pressing PB2 two times and then PB1
four times will set the transmitter to channel 24.
NOTE: When selecting a new channel, make sure each button press does not exceed 3.0 seconds.
When finished the transmitter Status LED will display the newly selected channel. The newly selected
channel must be transferred to the receiver by pressing and holding PB3 for up to 10.0 seconds or
until the transmitter Status LED turns off, which indicates that the transferring process is completed.
Make sure the receiver power is turned on during the process. Exit the transmitter function setting
mode by removing the batteries and moving the function dip-switch back to the Off position.
NOTE: When the transmitter keypad is set to type 1 the receiver must be reset (turned off and back
on), or the channel setting process must be executed 10 minutes after receiver inactivity.
NOTE: When you are changing the transmitter channel you must also change the receiver channel at
the same time prior to exiting the transmitter function setting mode (see the instructions above). If you
exit the transmitter function setting mode without pressing PB3 for up to 10.0 seconds to transfer the
newly selected channel to the receiver, you will have to change the newly selected transmitter
channel back to its previous setting. This can be done by reentering the transmitter function setting
mode and then pressing and holding PB1 and PB3 at the same time for up to 2.0 seconds; this will
reset the newly selected channel back to the previous setting.
Alternately, perform the remote pairing process (RX to TX) described in Section 2.1.3 Remote Pairing;
this will transfer the receiver channel to the transmitter. Repeat the channel setting process again if
you would like to reselect a new channel.
