Epson Equity LT-386SX User Manual - Page 43

Setting the Standby Mode Standby mode increases battery life by shutting off the LCD backlight, slowing down the CPU clock speed to 8 MHz, and decreasing the VGA controller clock rate. Standby mode is valid only when the Equity LT-386SX is not attached to an external monitor. The time you select for standby mode (00 to 60 minutes) is the length of time that can pass without keyboard input before the computer enters standby mode. Setting the standby period to 00 turns it off. Once you have specified a time for standby mode in SETUP, you can enable or disable this feature during operation by holding down the Ctrl key and pressing the left Shift and L keys simultaneously. When standby mode is enabled, the computer sounds two short beeps. Hold down Ctrl and press left Shift and L again to disable standby mode. The computer sounds a single beep to signal that standby mode is disabled. If you are installing or running software that requires a lot of disk access time, during which there is little or no keyboard input, it is best to set standby mode to 00 (off) to prevent the LCD from going dark. Setting the LCD Contrast This setting determines whether the LCD displays black letters on a white background (negative contrast) or white letters on a black background (positive contrast). During operation, you can invert the LCD screen contrast at any time. Hold down Ctrl and press the left Shift and I keys simultaneously to invert screen contrast. Using this key sequence does not affect the LCD contrast the computer uses each time you turn on or reset it. 1-24 Setting Up Your System
