Q24. A. What other HDDs can I use with the LT? Can I use an external HDD? Only the proper internal HDD from Epson can be used with the LT. Q25. A. How many HDDs can be used with the LT? Only one HDD is supported. LCD Displays Q26. Can I replace the EL (electroluminescent) element in the backlit LCD? A. Yes, you can. The replacement procedure is explained in Appendix A of the Equity LT User's Guide. However, it can be a rather tricky operation and we strongly recommend that your dealer do the replacement. Q27. A. What is the expected lifetime of the EL element? The EL element, like any kind of light bulb, will gradually lose brightness. "Lifetime" for the EL element is defined as the time it takes for the element to fall to half of the original brightness. This works out to approximately 500 hours at maximum brightness. You can extend this period by adjusting the brightness down, keeping the EL only as bright as needed in order to see the screen clearly. Q28. A. What is the "backlight period"? This is another feature that extends the useful life of the EL element. You can set an option with the SETUP command to have the EL turn off after a period of no keyboard activity. You can set the time in half-minute increments from 0.5 through 5.0 minutes. You can also set "NO Time Limit" to cause the EL to remain on constantly. After the EL turns off, you turn it back on by pressing a key. The backlight period value is stored in system CMOS RAM. Q29. A. What is the aspect ratio of the LCD display? The aspect ratio for both LCDs is 1:1.4. (The aspect ratio needed to obtain true circles is 1:2.4.) Equity LT - Common Questions and Answers - Page 5 of 9._ _ _ .

What is the expected lifetime of the EL element?
The EL element, like any kind of light bulb, will gradually lose
brightness. “Lifetime”
for the EL element is defined as the time it
takes for the element to fall to half of the original brightness. This
works out to approximately 500 hours at maximum brightness. You can
extend this period by adjusting the brightness down, keeping the EL
only as bright as needed in order to see the screen clearly.
What is the "backlight period"?
This is another feature that extends the useful life of the EL element.
You can set an option with the SETUP command to have the EL turn
off after a period of no keyboard activity. You can set the time in
half-minute increments from 0.5 through 5.0 minutes. You can also set
“N
O
Time Limit” to cause the EL to remain on constantly. After the EL
turns off, you turn it back on by pressing a key. The backlight period
value is stored in system CMOS RAM.
What is the aspect ratio of the LCD display?
The aspect ratio for both LCDs is 1:1.4. (The aspect ratio needed to
obtain true circles is 1:2.4.)
