Using the ES400 2 - 19
Resetting the ES400
There are two reset functions, warm boot and cold boot. A warm boot restarts the ES400 by closing all running
programs. A cold boot also restarts the ES400, and also initializes some drivers. Data saved in flash memory or a
memory card is not lost.
If the ES400 is not functioning properly, perform a warm boot first. If the ES400 still does not respond, perform a
cold boot.
Performing a Warm Boot
Hold down the Power button for approximately five seconds. As soon as the ES400 starts to boot release the
Power button.
Performing a Cold Boot
To perform a cold boot, simultaneously press the Power button and the 1 and 9 keys.
