After the installation, the CPU canbeswitchedbacktothohlgherspeed. lnstallation/Support Tips tfasoftwampaokagedoeanotappeartobe compatible wifh the Equity LT286e, try switching Power the CPU speed to 8 MHz before giving up. The Equity LT-2880 AC adapter is an auto-sensing unit which adjust8 automatically between lCX&240 V, So/So l-k. lhmfore, it can be used anywhere in the world without ape&l adjustment. When using the Equity LT288e on battery power, conservation measures are available and should be used. lb3eare: 1) set the backlight period option tc the shortest available setting with SETLCD, 2) set the brlghtneas and contrast control8 as low as is comfortable, 31 run at 8 MHz, and 4) use the HDDPSWE feature to automatically turn the HDD off at times when it is not being aweawd constantly. Periodically, discharge the battery completely. This will help to minimize the memory effect encountered with NiCad batteries. After the complete discharge, give the LT-286e a full, &hour recharge. This will help to keep battery charge life aa great as possible. Video - When using the Equity LT-288e with a monochrome monitor, lf your aoftwam requires that you specify a display type, select EGA 640 X 350 MONO. Mass Storage Be careful when handling the removable hard drives. Unneoessary roughness can set off the shock indicator. Software Problems When installing a copy-protected software package on the Equity LT-288e, sat the the CPU speed to 8 MHz. This has been found to have fewer conflicts Equity Series Computers 8/1/89 LT286e-5 EQUITY LT 286e ( Information Reference List ( Engineering Change Notices None.
