9. TRANSMITTER OPERATION
1. Make sure the two alkaline batteries are installed correctly. Do make sure to use alkaline
type batteries for longer operating time between battery replacements. Rechargeable
batteries can also be used (1,600mA or higher recommended).
2. Turn “on” the power switch located on the top left hand corner of the transmitter unit (refer
to diagram below). The Status LED on the face of the transmitter will display a green light
for up to two seconds when the power switch is turned “on”. Make sure the red EMS
pushbutton is elevated (on), by twisting it 1/4 turn clockwise.
If the Status LED displays a red blinking light with on  0.1 second and off  2.0 seconds
or no light at all, this indicates that the two “AA” batteries in the transmitter must be
replaced. If the Status LED light is blinking red, on  2.0 seconds and off  0.1 second, it
means that the transmitter unit is locked due to a jammed (closed) or defective pushbutton
contact. This important safety feature is designed to prevent any unexpected crane
movement at system start-up caused by a defective or jammed (closed) pushbutton contact.
After turning “on” the transmitter unit, the system will go into self-diagnosing procedure.
After 0.5 second, the transmitter key functions and receiver MAIN will be activated.
3. In case of an emergency, press down the red EMS button will immediately deactivates the
receiver MAIN contact relay. To reset the EMS function and restart the system, just turn
the red EMS button clockwise to enable the red button to elevate to its non-active position.
4. Please note that conflicted movements are interlocked to one another for safety purpose.
Pressing conflicted commands at the same time will result in a non-transmission.
