B. Assigned Channel Scheme (preset system channel)
Both transmitter and receiver is assigned with a matching preset channel (channel
01~62). Tandem, random access and pitch & catch configurations “must” set to
assigned channel scheme.
1) Reset the STOP button (Status LED turned green for
up to 2.0 seconds, transmitter power on).
2) Press and hold both PB5 and PB6 at the same time
for up to 3.0 seconds (Staus LED blinks orange).
Let go of both PB5 and PB6 when LED-A and LED-B
turned red.
3) Entered programming mode with Status LED displays 1x
orange blink for firmware version, remote pairing and IR
programming.
2x orange blinks for transmitter channel programming
, 3x orange
blinks for PB1~PB7 function programming, 4x orange blinks for frequency range
indication, 5x orange blinks for TAC programming.
4) Enter transmitter channel programming mode by press and hold both PB5 and PB6 at
the same time for up to 3.0 seconds (LED-A and LED-B turned red). Let go of both
PB5 and PB6 when Status LED dispays the current transmitter channel setting. A
green blink represents the tens (+10), a red blink represents the units (+1) and
constant orange represents unassigned channel. For example, 1x green blink followed
by 5x red blinks is channel 15.
5) Change transmitter channel by pressing PB5 for up to 2.0 seconds (Status LED turns
red during each press) to increment the units (+1) and press PB6 for up to 2.0
seconds (Status LED turns green during each press) to increment the tens (+10). For
example, press PB6 two times and then PB5 four times is channel 24 (Status LED
blinks 2 greens and 4 reds). Make sure each button press does not exceed 3.0
seconds after release. Also make sure the newly selected channel indication is
shown on the Status LED before proceeding to the next step.
6) Transfer the newly selected channel to the receiver by pressing the green START
button until the Status LED turns to constant green (transfer complete). Turn off the
transmitter power if constant green is not shown on the Status LED after more than
5.0 seconds (transfer incomplete); the transmitter will revert back to its previous
channel setting. Make sure the receiver power is turned on and within the operating
distance during the entire process. The transmitter and receiver channel must be the
same in order for the entire system to work.
7) Exit transmitter channel programming mode by pressing down the STOP button
(transmitter power off).
Important Note:
Step 6 illustrated above is strictly required if you are intending to change the entire system
channel (both transmitter and receiver). The entire system no longer works if step 6 is skipped
because the transmitter and receiver channels are now different (new vs. old). In this case you
would have to redo step 1~4 and step 6 to transfer the newly selected transmitter channel to
the receiver.
