SIAC's battery voltage is measured and shown at stations service display. An acoustic signal “normal beep” indicates the “ok” case. If the battery voltage is low there is a “warning” signal – several beeps at higher frequency.

In case of no feedback signal the battery voltage is below the critical level and the SIAC can not be used. Battery service is needed.

Voltages measured are stored in stations backup memory. Information consisting of SIAC ID and the battery voltage can be read out by using SI-Config.

We recommend conducting the test before every event. Stations should be placed in the event centre, so athletes can use it early before start.
