What is the "backlight period"?
A.
This is another feature that extends the useful life of the backlight element
and the battery charge.

can set the time in minute increments from 1 through 60 minutes. You
can also set the screen to remain on constantly. After the screen turns
off, you can turn it on by pressing any key.
Q31.
How are colors distinguished on the LCD display?
A.
By gray scales. The gray- scale mode governs the way the LCD screen

to enter LCD adjustment mode. In this mode, adjust the gray scale; just
press "S" to see the different gray - scale levels. Select the level that works

Q32. How long does it take to charge the battery pack?
A.
8 hours for a full charge. The computer can be on or off. The battery
pack can not be overcharged, so it is perfectly safe to leave it connected
for more than 8 hours. Also, remember that NiCad batteries need to be
fully discharged from time to time for maximum effective life. So
occasionally let the battery pack discharge to the point that the system
completely shuts down.
Q33. Does the battery pack have to be installed on the computer?
A.
No. The AC adapter will charge the battery either on or off of the
computer. This allows you to have extra battery pack(s) charged and ready
to use.
Q34. Can I use any other AC adapter?
A.
No! use only the Epson AC adapter that comes with the LT- 286e.
You
