1.3 Precautions If reading the internal clock with INT21h the significant data should include and be limited to the seconds digits. On this terminal the time is read directly from the RTC so that the correct time can be attained at any moment, even during extended continuous use. As a result the 1/100 of a second digit is ignored. (refer to Chapter 7.3 “Clock Control Driver”.) To count time, the counter of DOS or the function provided for reading time must be used.

If an LB1 event (low main battery voltage) occurs, the alarm buzzer starts sounding and system operation is suspended about 10 minutes later. If the alarm buzzer starts sounding, terminate the current operation as soon as possible and recharge the main battery. This system will not execute an alarm indication to be displayed on the LCD screen for an LB2 event (low sub-battery voltage) or LB3 event (low SRAM card battery voltage). Therefore, the application program side must acquire these ala

The backlight is turned off by means of the ABO (Auto Backlight OFF) function. However, it is turned off 1.3 seconds after the setup time. This is because the system has 1.3 seconds of monitoring time before the internal timer is started. During the process of loading Windows after boot-up, do not press the Power switch. Do not press the Power switch because a processing request is issued before the process handler is installed, resulting that the processing following the request can no long
