This system will not execute an alarm indication for an LB2 event (low sub-battery voltage) or
LB3 event (low SRAM card battery voltage). Therefore, the application program side must
acquire the alarm status via the system library and display an appropriate alarm message.
If the volume of the buzzer is set to zero by the System Menu or system library, the LB1 (low
main battery voltage) alarm will not be heard. Also, other sounds issued by the system will be
inaudible.
If the system is booted from a PC card and if a large-size program that resides on the card is
called from AUTOEXEC.BAT file, an error may result. To avoid this problem refer to Chapter
4.2 “How to Write CONFIG.SYS and AUTOEXEC.BAT".
The time limits that can be set for the Auto Power OFF (APO) function are 0 minute, 1 minute
and 30 seconds, 2 minutes and 30 seconds, up to a maximum of 15 minutes and 30 seconds.
This timer has an error of +/-23 seconds.
Do not open the battery compartment lid while the power is on. If it is opened accidentally, an
emergency alarm sounds. In case such the event occurs, close the lid at once.
When you change the main battery, be sure to switch off the power before opening the lid.
An SRAM card formatted with the DT-9000 (a Casio handy terminal) cannot be used or
formatted with the IT-2000.
If the battery pack is installed for the first time after purchase, or if it is installed after the main
unit has not been used for a long period of time, install the battery and wait approximately eight
seconds before turning the power on. This must be done because it takes approximately eight
seconds until sufficient power can be raised for the emergency process. And, during this
interval the power cannot be turned on even if the Power switch is turned on.
If the power is turned on for the first time after purchase and there is no installed application,
the System Menu will always appear. Before using applications call this System menu to install
them. (refer to Chapter 7.4.3 “Operation Check on IT-2000 (Using COM2KEY/XT)”)
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.
