2. FUNCTION SETTINGS
2.1 TRANSMITTER
2.1.1 Channel Settings
Enter transmitter Function Setting Mode by moving the function dipswitch located inside the
battery compartment to “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 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 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, press PB2 two times and
then PB1 four times is channel 24. When finished the transmitter Status LED will display the
newly selected channel. Then you “must” transfer the newly selected channel to the receiver
by press and hold PB3 for up to 10 seconds or until the transmitter Status LED turns off, the
transferring process is completed. Make sure the receiver power is turned on during the
process. Skip this process if changing receiver channel is not required. Exit transmitter
Function Setting Mode by taking out the batteries and move the function dipswitch back to “off”
position.
Note 1: when selecting a new channel make sure each button press does not exceed 3 seconds.
Note 2: do not press PB3 for up to 10 seconds if you do not want to change the receiver channel.
Note 3: when transmitter keypad is set to type 1 the receiver must be reset (turn off and back on) or execute the
channel setting process 1 minute after receiver inactivity.
Important Note:
Press and hold PB3 for up to 10 seconds to transfer the newly selected transmitter channel to
the receiver is strictly required if you intend to change the entire system channel (both
transmitter and receiver) during the process. The entire system channel will no longer match
if this transferring process is skipped, resulting in new transmitter channel vs. old receiver
channel. In this case you would have to change the newly selected transmitter channel back
to its previous setting by reentering the transmitter Function Setting Mode and then press and
hold PB1 and PB3 at the same time for up to 2 seconds; this will reset the newly selected
transmitter channel back to its previous setting. Or perform section 2.1.4 Receiver-to-
Transmitter Pairing process; this will transfer the receiver channel to the transmitter.

2.1.2 Keypad Type Settings
Enter transmitter Function Setting Mode by moving the function dipswitch located inside the
battery compartment to “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 PB4 for up to 1 second to
go into the Keypad Type Setting Mode. At this point the Status LED will blink red showing
the current keypad type. A green blink represents the tens (+10) and a red blink represents
the units (+1). For example, two (2) red blinks is keypad type 2.
Now select new keypad type by pressing PB1 and PB2 on the transmitter. Press PB1 to
increment the units (+1) and PB2 to increment the tens (+10). For example, press PB1 two
times for keypad type 2 and three times for keypad type 3. When finished the Status LED
will display the newly selected keypad type. Exit transmitter Function Setting Mode by taking
out the batteries and move the function dipswitch back to “off” position.
Note: when selecting a new keypad type make sure each button press does not exceed 3 seconds.
2.1.3 Transmitter Inactivity/Sleep Timer Settings
After entering transmitter Function Setting Mode, press and hold both PB2 and PB4 at the
same time for up to 1 second (Status LED orange) and then let go (Status LED displays
current sleep timer setting). A green blink represents the tens (+10), a red blink represents
the units (+1) and an orange blink represents constant ON (sleep mode disabled). For
example, one (1) green blink followed by five (5) red blinks is 15 minutes.
Select new timer value by pressing PB1, PB2 or PB3+PB4 on the transmitter. Press PB1 to
increment the units (+1), PB2 to increment the tens (+10) and PB3+PB4 to constant ON (sleep
mode disabled). For example, press PB2 two times and then PB1 four times is 24 minutes.
Make sure each button press is executed within 3 seconds. The timer value available for
programming is 1~60 minutes and constant ON so if set to 60+ minutes the sleep timer setting
will automatically default to constant ON (sleep mode disabled). When finished the transmitter
Status LED will display the newly selected sleep timer value. Exit transmitter Function Setting
Mode by taking out the batteries and move the function dipswitch back to “off” position.
