General Operating Procedures

1. Reset the STOP button, located on the top left corner of the transmitter, by rotating it 

clockwise or counterclockwise. The button will pop up. Turn on the transmitter power by 
inserting the power switch key and rotate to the ON ( I ) position.

2. After turning on the transmitter power, check the Status LED on the transmitter for any 

sign of system irregularities (refer to manual section: Transmitter Status LED Indications). 
If the transmitter is in good working order the Status LED will display solid green for up to 
2 seconds at power on (no faults detected).

3. Rotate the power switch key further to the START position and hold it there for up to 2 

seconds (Status LED solid green). When the receiver MAIN relays are activated, the 
Status LED will change from solid green to solid orange (system on). The power switch 
key will retract back to the ON ( I ) position when released. The same START position 
becomes an auxiliary function thereafter (refer to manual section: START + AUX 
Function). Pressing any pushbutton prior to executing the START command at system 
startup will result in no signals transmitted (Status LED blinks orange). During transmitter 
inactivity (pushbuttons not pressed), the transmitter will automatically switch to standby 
mode, with an orange blink on the Status LED at every 4-second interval. Turn off the 
transmitter power when not in use to save battery power.

4. In case of an emergency, press down the STOP button to disconnect the receiver MAIN 

relays (Status LED blinks 3 reds and then shuts off). To resume operation, rotate the 
STOP button clockwise or counterclockwise. The button will pop up. Then execute the 
START command to reconnect the receiver MAIN relays. For safety, executing the START 
command is strictly required every time the transmitter is turned on or after every STOP 
button reset. After 5 minutes of inactivity (pushbutton not pressed), the receiver MAIN 
relays are temporarily disconnected (refer to manual section: Inactivity Timer Settings). 
The Status LED blinks 3 reds and then shuts off. Execute the START command to resume 
operation (refer to manual section: Start Function Settings). Turn off the transmitter power 
by rotating the power switch key counterclockwise to the OFF ( 0 ) position; it will 
disconnect the transmitter power and the receiver MAIN relays altogether. Rotate the 
power switch key further counterclockwise to release the key.
