Sleep Timer Mode
The Sleep Timer mode is an energy-saving feature that enables 
you to set a time for the monitor to power on and off at the same 
time every day. This also extends the life of the backlight bulbs in 
the monitor. The Sleep Timer has five settings:
Set Current Time
Set Sleep Time
Set On Time
Timer: On/Off
Sleep Now
To set the timer: 
1. Press the Menu button on the monitor front panel to display 
the Advanced Menu.
2. Scroll down and highlight Management.
3. Press the Menu button to select Management. 
4. Scroll down and highlight and select Sleep Timer > Set 
Current Time.
You must set the current local time before you reset the time for 
Sleep Time or On Time. Note that the time is displayed in a 24 
hour clock format. For example, 1:15 p.m. displays as 13 hours 
15 minutes.
5. Press the Menu button once to enter the adjustment mode for 
hours.
