General Operating Procedure
1. Reset the red emergency stop button located on the top left side of the transmitter
handset by rotating it either clockwise or counterclockwise. The red button will pop up.
2. Turn on the transmitter power by inserting the black-colored key into the power key slot
(located on the top right side of the transmitter handset) and rotate it clockwise to the ON
position.
3. After turning on the transmitter power, check the Status LED on the transmitter handset for
any sign of system irregularities (
see Section 7.2 on page 58
). If the system is normal,
the Status LED will illuminate green for 2 seconds.
4. If there are no signs of any system irregularities, then continue to rotate the power key
clockwise to the START position for up to 2 seconds. This will activate the receiver MAIN
(depends on JP3 setting;
see Section 4.2.5 on page 43
). Thereafter, the same START
position will become an auxiliary function with momentary contact (
see Section 4.2.2.6 on
page 37
