     Standby Wake from RTC Demo for Portenta C33 
 
     This example demonstrates how to  wake up the Portenta C33 from standby mode using the included RTC (Real Time Clock).
-    The device will go to sleep for 1 second and then wake up. When the device is awake you will see the board's blue LED turned on. 
+    The device will go to sleep for 5 seconds and then wake up. When the device is awake you will see the board's built-in LED turned on. 
     Effectively, you will get the same effect as with blink. 
 
     On the Portenta C33 with the peripherals turned off you can expect around 60uA of current consumption in standby mode.
