That option is for The Equity Ill+ has a power supply that is switchable between 115 V, for USA and Canadian use, and 230 V, for use in other countries. The voltage switch is located at the EXTENDED memory ONLY. - - - rear of the CPU between the AC inlet and the AC outlet (see figure below). If you are installing an EGA or VGA card, select SPECIAL OPTIONS as display type in SETUP. This holds true even when you are using a color or monochrome monitor with these cards. Option card access slots Voltage swtch - When installing a hard disk drive, be sure to consult the drive type table (on page EQIII + -7) for the drive type which fits the drive you are installing. Third Party Option Boards - - AC power Inlet AC power outlet If you find that some third party option boards do not function properly in the Equity Ill+ at the RS232C serial port higher speed, try setting the CPU speed back to 6 MHz or 8 MHz. WARNING! The voltage is not changed between the AC inlet and the AC outlet. - - - If the CPU is switched for 230 V in When installing a memory expansion option board, make sure that it is a board capable of supporting order to function in Europe, only peripherals certified for use the higher bus speed (10 MHz or 12 MHz) of the at 230 V should be plugged into the outlet.

If the drive does not function normally, make sure - - - If a software package does not appear to be that the drive type has been correctly selected in compatible with the Equity Ill+, try switching the SETUP. Also check that any special drivers that CPU speed to 6 MHz and/or 8 MHz before giving may be necessary have been installed correctly. up. Some software packages (e.g., Microsoft Chart 1.01 and Think Tank 1.001) have been found to Installing Hard Disk Drives - - - function only at 6 MHz and 8 MHz. It is recommended that a 16-bit AT -type hard disk controller be used in the Equity Ill + . If you must for some reason use an 8-bit XT-type controller, select drive type NONE in SETUP. - - - If you are having difficulty in formatting the hard disk drive, try starting over with the Unconditional Format option in diagnostics.
