Functional Description Of The Command Receiver Unit Via Radio - Rx Unit - SICE S 58 LL Manual De Instrucciones

When it turns on and stays on, this informs the user that the power supply battery

Once the TX unit LED turns on, you can continue transmitting for limited time. After
this period of time, which depends on the type of use and general efficiency of the
batteries, the TX unit will turn off and remain inactive due to a lack of power.
The LOW BATT LED will turn off when the battery charger is connected to the TX unit.
FUNCTION OF THE RED STOP LED
The STOP LED turns on and remains on for the entire time that the "STOP" button is

If an emergency stop is required, use instead the network switch located on the
