Do not operate the system until you are familiar with radio-controlled operation. If you are not
familiar with radio-controlled equipment operation, contact your supervisor before attempting to
use the radio control system.
The following list describes the safety and operational features and characteristics of the transmitters; refer to
Figure 1.
• Status LED. The status LED provides an indication of the transmitter operation. Refer to Maintenance
and Troubleshooting for a detailed description of the status LED indications.
• Command Switches. The command switches are labeled according to their function.
- If opposing commands are attempted, i.e., two commands that conflict with each other, in most
cases no function results. In the case of ON/OFF functions, OFF predominates.
• On. Turns on the transmitter and puts the system in the active mode. The transmitter remains active until
the OFF/STOP is pressed, or the transmitter turns itself off (see Auto Off below).
• Off/Stop. While depressed, this command sends an EStop command to the receiver. The transmitter
does not need to be actively “ON” to send this command. When this button releases, the transmitter turns
off.
• Auto Off. The transmitter turns itself off if no commands have been sent for a predetermined amount of
time. Normally, this time is set to 15 minutes; however, it may be programmed from 0 to 60 minutes, or
disabled using a RAC16A portable handheld programmer (1 to 60 = minutes, 0 = disabled).
