1. Batteries
_ Make sure the four “AA” alkaline batteries are installed correctly, the labels on the
battery holder will tell you which side is “up” and which side is “down”. Use 2,000mA alkaline
type batteries for optimum operating time between replacements. If rechargeable batteries are
used, for optimum operating time between replacements, select ones rated above 1,600mA.
NOTE!!! To avoid battery leakage, please take out the batteries from
the battery compartment if the transmitter is not operated for a long time.
NOTE!!! When screw the battery cover on the transmitter bottom casing, be
sure to put the battery cover to the position as attached drawing pointed.
If not, the batteries might be leaking or even burning.

Startup Procedure _ M
ake sure the red EMS button is elevated prior to
inserting the transmitter power key, by pulling it upward. Then insert the
power key into the key-slot located on the top right-hand side of the
transmitter (refer to the diagram at right). The transmitter status LED on the
top-center location of the transmitter will display a constant green light for up
to 2 seconds when the power key is inserted, followed by series of blinking
green lights for up to 3 minutes. Press and hold the START/AUX pushbutton
for up to 1.0 second to activate the receiver MAIN relay and transmitter
pushbutton functions. If START/AUX pushbutton is not pressed after turning on the transmitter power,
both receiver MAIN and all the transmitter pushbutton functions are ineffective.
Power off stop (POS): For Mode 0 only. Pull out the transmitter power key, the transmitter will send
emergency stop command automatically. Then red status light flashes for 3 times and deactivate the MAIN
relay off at the same time.

4. Receiver Main Relay Deactivates in 5 Minutes _ Your receiver MAIN contact relay is
programmed to drop (open) the “Main Line Disconnect Contactor” after 5 minutes of inactivity,
that is 5 minutes after the last pushbutton is released. Pressing any pushbutton will close the
MAIN relay and start the timing sequence over again. If your crane or hoist is equipped with
VFD drive this can sometimes cause an unacceptable delay. In this situation we suggest you
