| A "HIGH RAD MODE" switch is located on the Faraday Cup Control Module. When this switch is in the "OFF" position the LE cup will lift instantaneously and the audible and visual warning will be active for 15 seconds. When this switch is in the "ON" position there will be a 15 second delay between pushing the LE Cup "OUT" button and the actual lifting of the LE Cup, as well as the 15 second audible/visual warning. | A "HIGH RAD MODE" switch is located on the Faraday Cup Control Module.
