11. Audible beeps and indicators
• Long beep – will be heard after the SiS-PM is connected to the computer USB port
after the self test;
• Short beep – will be heard by switching of the manageable sockets on and off;
• Continuing beeps – hardware event schedule is lost – for example if the power
supply was disrupted for a long period. These beeps can be stopped by pressing the
Silence button on the side of the SiS-PM(S);
• Alarm beep – will be heard if the managing command cannot be completed. For
example if there is a command to switch the socket on but SiS-PM is disconnected
from the power supply. The alarm will be heard every second for a minute, after that
every 8 seconds.
• Indicator “POWER” is on - means there is power on the sockets marked with the

• Indicator “Socket x” is on – means there is power in this particular socket
• Main rocker switch is light up – means SiS-PM(S) is connected to the power supply
and the SiS-PM(S) is active.
