* Advanced Controls – the system utilizes dual advanced microprocessor controls with
32bit CRC and Hamming Code, providing ultra fast, safe, precise, and error-free encoding
and decoding.
* Frequency Hopping RF Transceiver – the system automatically search-and-lock onto a
free and uninterrupted channel at every system startup or during operation when
encountering radio interference. The system is also capable of two-way communication
between the transmitter and receiver and as well as receiver to receiver with system status
feedbacks.
* Programmable Transmitter Access Card (TAC) – the optional transmitter access card
feature (TAC) further guard against any unauthorized personnel from operating the
transmitter. The TAC can also be individually programmed unlocking any specific function
or functions on the transmitter allowing a more experienced or qualified user to operate.
* Zero-G Sensor Imbedded – the transmitter is embedded with a Zero-G sensor to guard
against any unintended control of the crane or equipment when transmitter is thrown or
dropped.
* Wireless Remote Pairing Function – system information can be transferred wirelessly
between two transmitters or between a transmitter and a receiver without the hassle of
resetting the spares.
* Reliable Joysticks and Switches – the in-house designed joysticks and levers are rated
for more than five million operating cycles.
* Low Power Consumption – requires only four “AA” alkaline batteries for more than 100
hours of uninterrupted operation between replacements.
* Durable Nylon and Fiberglass Composite Enclosures – highly resistance to breakage
and deformation even in the most abusive environments. The receiver enclosures and
output cables are UL94-V0 rated. The transmitter and receiver enclosures are IP66 rated.

A. Unassigned Channel Scheme (no preset system channel)
When both transmitter and receiver is set to unassigned channel scheme (no
preset channel), the system automatically search and lock onto a free and
uninterrupted channel at every transmitter startup. Pitch & Catch configuration
“cannot” set to unassigned 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 (Status 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) Select transmitter channel programming mode (Status LED 2x orange blinks) by
press and hold PB6 for up to 3.0 seconds (LED-B turned red). Let go PB6 when
Status LED turns to 2x orange blinks.
5) 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 displays 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.
6) Change transmitter channel to “unassigned channel” by press and hold both PB5
and PB6 at the same time (Status LED displays constant orange for unassigned
channel). Make sure constant orange is shown on the Status LED before
proceeding to the next step.
7) Transfer the unassigned channel setting 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. When transmitter is set to
“unassigned channel”, the receiver must also set to “unassigned channel” in
order for the entire system to work.
8) Exit transmitter channel programming mode by pressing down the STOP button
(transmitter power off).

B. Assigned Channel Scheme (preset system channel)
Both transmitter and receiver is assigned with a matching preset channel (channel
01~62). Pitch & Catch configuration “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 (Status LED blinks orange).
Let go of both PB5 and PB6 when LED-A and LED-B

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 displays 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.
