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 alarm status via the system library and display an
appropriate alarm message on the screen.
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, 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 once formatted with the DT-9000 cannot be used or formatted with IT-2000.
If the battery pack is installed for the first time after purchase, or if it is installed after the
IT-2000 unit has not been used for a long period of time, install the battery and wait for
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. To start up the application, the application must be
installed first on the IT-2000. (refer to Chapter 8.4.4 “Installation of Application Program” )
