The Twister 2X is a highly sophisticated industrial radio control system. The versatile
features of the Twister 2X permits a wide range of industrial applications. The Twister 2X
industrial radio control system can be used to control all types of cranes, building
construction equipment, automatic control systems, mining equipment, and many others.

The Twister 2X incorporates numerous safety circuits that guaranty maximum security and
ensure the system is resistant to other radio interference. The major features of the Twister
2X industrial radio control system is as follow:

* Highly evolved software that have redundant error checking and correcting capabilities

to ensure 100% error-free transmission, decoding, and control of output relays. These
software designs include CRC (Cyclical Redundancy Check Code) and Hamming
Codes (Error Recovery).

* The encoding system utilizes an advanced microprocessor for 100% error -free data

transmission. The availability of 65,536 sets of unique security ID codes will ensure
that only commands from the matching control transmitter can be carried out without
any interference from other radio systems.

* The decoding system utilizes dual advanced microprocessors, which ensures 100%

error-free calculation, bit checking, and correction of incoming transmitted data.

* The system also utilizes an additional central microprocessor for data comparison and

cross checking between the two decoding microprocessors to ensure 100% error-free
decoding and control of all output relays. When faults are detected via this central
microprocessor, for maximum safety, the entire system will be shutdown within 0.50
second to avoid any undesired crane movements.

* The system utilizes PLL synthesized RF for means of data transmission. It allows the

user to select from a wide range of frequency channels best suited for the environment.
The frequency channel is selected via a dip-switch in the transmitter unit and LCD
control panel in the receiver box. The receiver system also has the ability to auto scan
from a wide range of frequency channels. The receiver system will search and locked
on to the intended matching transmitter unit.

* Optional dual advanced receiving system for optimum receiving capability.

* The Twister 2X systems are equipped with numerous self-diagnosing features.

These include transmitter low voltage detection  warning  system automatic
shutdown, faulty pushbutton and joystick contact switches detection, faulty MAIN
contact relay detection, faulty relay boards detection, faulty EEPROM detection,
faulty PLL synthesizes RE unit detection, and incorrect security ID code detection.

The Twister 2X system is relatively simple to use. However, it is very important to observe
the proper safety procedures during ope ration. When use properly the Twister 2X systems
will enhance productivity and efficiency in the workplace.

The following instructions should be strictly followed:

1. Make a daily check of the transmitter casing, joysticks, and pushbuttons. Should it
appear that anything could inhibit the proper operation of the transmitter unit, it should
be immediately removed from service.

2. The transmitter voltage should be checked on a daily basis. If the voltage is low, the
battery pack should be recharged or replaced.

3. The emergency stop pushbutton (EMS) should be checked at the beginning of each shift
to ensure they are in the proper working order.

4. In the event of an emergency, activate the emergency stop pushbutton immediately.
Then turned the power “off” from the main power source of the equipment.

5. The power switch should be turned “off” after use and should never left the power “on”
when the unit is unattended.

6. Do not use the same RF channel and ID code as any other unit in use at the same
facility (within 300 -meter range / 900 feet).

7. Ensure the waist belt is worn at all time during operation to avoid accidental dropping.

8. Never operate a crane or equipment with two (2) transmitter units at the same time with
same RF channel and ID code.

This device complies with Part 15 of the FCC Rules. Operation is

subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operations.

Changes or Modifications not expressly approved by the party responsible
for compliance could void the users’ authority to operate the device.

Each transmitter unit is equipped with up to two (2) joysticks with single or double axis per
joystick. Please see the table below for different joystick settings:

TYPE FUNCTION

Linear (step -less)

1-Speed No acceleration.
2-Speed Shared acceleration relay.
2-Speed Separate acceleration relay.
2-Speed

3-Speed Shared acceleration relay.
4-Speed Shared acceleration relay.
5-Speed Shared acceleration relay.

0-Speed Contact Relay

Note A: When 2nd speed contact relay is activated, the 1st speed contact relay will be

deactivated.

Separate acceleration relay / 1st and 2nd speed relay interlocked (refer

to note A).

0-speed (neutral position) can also be equipped with contact relay for

connection to crane’s braking system.
