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 1,600mA or above.
2. Startup Procedure _ You must first make sure that 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 diagram to the 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. Then press and hold the START/AUX pushbutton
for up to 1.0 second to activate the receiver MAIN relay
(depending on JP1 setting on page 17). Thereafter, the
START/AUX pushbutton becomes an auxiliary function, which can be used for lights, horn, etc…
When a command pushbutton is pressed, the Status LED will display a blinking green light informing
the operator that the command signals are being transmitted. Please refer to the table below for
transmitter status LED display information.

4. Receiver Main Relay Deactivates in 5 Minutes _ Your receiver MAIN 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 remove the JP2 jumper (refer to JP-2 setting on
page 17) then the MAIN relay will remain closed until the “Stop” command is received or the main
power source to the equipment is turned off.
5. EMS & Restarting _ In case of an emergency, pressing down the red EMS button will immediately
deactivates the receiver MAIN relay. When EMS button is activated (depressed), the transmitter
status LED will display a red blinking lights that is “on” _ 0.5 second and “off” _ 0.5 second (refer to
the chart above). To reactivate the receiver MAIN relay, just pull up the red EMS button and then
press and hold START/AUX pushbutton for up to a second (depending on JP1 setting on page 17).
