Callout  Button  Description 
A-Stop Button  Used to transmit an A-Stop signal received by any Command machines equipped with the A-Stop system within range. The A-Stop signal will continue to transmit until the A-Stop Reset (5) is pressed.(1) 
Stop LED Indicator  Blinks when A-Stop command is actively being transmitted. 
Reset Indicator  Blinks after an A-Stop Clear message is transmitted. 
Clear Button  Used to signal to any Command machines in the area to exit the A-Stop mode. Each transmitter that has signaled an A-stop must be pressed before the affected machine can resume operation.(2) 
A-Stop Reset Button  Used to stop transmitting the A-Stop signal. The A-Stop Reset button (5) will only stop the transmission of the A-Stop signal, this button will not clear an affected machine to resume operation. 
Test Button  Used to initiate an A-Stop system test(3) between the transmitter and all Command machines in range of the transmitter. The test button (6) is a momentary button. 
Test/Power Indicator  Blinks periodically under normal operation. 
Alarm Silence  Used to silence the audible alarm during an A-Stop event. 
Low Battery Indicator  Used to show a low battery charge. 
10  Battery Charge Indicators  Used to show the charging status of the transmitter battery. 
11  Charging Port  Used to charge the transmitter.(4) 
(1) Only the transmitter that sent the A-Stop signal can clear the A-Stop command.
(2) Pressing the Clear button (4) does not allow the autonomous machine to resume the task the autonomous machine was assigned before the A-Stop was initiated. The Clear button (4) must be pressed and the user lock removed in the office before the autonomous machine will resume its original assignment it had before the A-Stop was activated.
(3) For Test Station testing when used with the Stop button.
(4) Use only the supplied charger 373-8621 Battery Charger to charge the transmitters.

The transmitter has various modes of operation. Refer to Table 2 for more information.

Table 2

Charge Indicator LEDs 
Ready LED (Green)  Charging LED (Yellow)  Fault LED (Red)  Indicated Condition Description 
    LED illuminates briefly after transmitter is attached to charger. LED will stay illuminated after charging is complete. 
  LEDs illuminate when the transmitter is being charged.(1) 
  LEDs will illuminate when the transmitter is ready for charging but the temperature of the transmitter is out of range(2). In a suitable environment, charging will begin after the transmitter reaches a temperature in the allowable range. 
    LED will illuminate when a latched fault condition is present. This condition can be the result of a bad battery, circuit failure, chip over temperature.(3) 
(1) The charging will begin at a high rate charge followed by a top off charge.
(2) Transmitter will only be charged if the temperature is between 20° ± 25°C (68.0° ± 45.0°F).
(3) If this condition is present, unplug the transmitter from the power supply and retry before troubleshooting further.

Note: If none of the LEDs illuminate after the transmitter is connected to the charger, remove the transmitter from service.
