BHT is equipped with one SD card slot which can accommodate a micro SD card, a microSDHC or
a microSDXC card. When selecting an SD card for the best compatibility and performance with
BHT-1800 series, please make sure of the capacity you need. For the use of SDXC card, please use
a new card and make sure that it has not been used in other host devices (computers, cameras, or
SD card readers).
Caution of data loss
When the main battery is removed or drained, the backup battery on the main board takes over to
supply BHT and keep it in suspension. A fully charged backup battery will retain the data in the RAM for
3 minutes. When the backup battery is drained out as well, BHT will shut down, and all unsaved data
will be lost.
If you want to put away BHT for a couple of days, you should be aware that data loss occurs when the
main battery and backup battery discharges completely. Therefore, it is necessary to backup data and
files before putting away BHT.

2.3 Touch Screen

screen, which helps ease reading under dim environments, can be controlled manually and
