2.2.3 Notes for Using the BHT Windows desktop on the LCD
The Windows desktop shown in this manual may be a little different from that in the actual screens on
the LCD.
(Windows desktop sample)
This task tray also may be a little different from that in the
actual screen.
No refreshing of the LCD screen when on standby
To minimize the power consumption, the BHT automatically switches to the standby mode after it has not
been operated for the specified period*.
In the standby mode, the LCD is not refreshed so that icons on the task bar and task tray may not be
displayed or refreshed or that the calendar clock may not show the correct date or time.
* The default is one second. The period can be changed in user programs. For details, refer to the
"BHT-200-CE API Reference Manual" or "BHT-200-CE Class Library Reference Manual."
Opening the wireless communications device
To minimize the power consumption, the wireless communications device in the BHT is not working in
regular operation.
To make the BHT ready for wireless communication, you need to open the wireless communications
device with the RF Open/Close switches in System Menu or by coding in user programs.
For the opening/closing procedure with the RF Open/Close switches in System Menu, refer to Section
2.5.4, "[3.8] Radio Frequency, Displaying the wireless module version and opening/closing the RF
device."
For coding in user programs, refer to the "BHT-200-CE API Reference Manual" or "BHT-200-CE Class
Library Reference Manual."
