Standby mode/hot keys
The STLED325 also features standby power management to host. The system can enter
into standby mode by:
●
Pressing the front panel standby key
●
Remote control standby key
On entering standby mode PWR/STBY LED (D4) turns red. MUTE LED (D3) also turns ON.
“STBY” is displayed on the LED panel for about two seconds (refer to
) after which
the complete display is blanked (discrete LEDs also turned off, refer to
). If the
system was in display RTC mode (time/date display) when the standby key was pressed,
the 7-segment display does not get blanked but displays RTC during standby mode.
(discrete LEDs are off). During standby all the front panel and RC keys except the hot keys
are non-functional.
