1. Outline
1.1. Application Implementation Steps
The following steps describe a typical process from purchase of a BHT to implementation of a business application
using the BHT.
S
tep 1: Confirm that the BHT works properly. (Refer to the Operators Guide or Hardware Users Manual.)
Step 2: Determine a set-up procedure considering the application environment and develop applications for the BHT.
Refer to"2 Set-up of BHT" in this manual for how to set up the BHT.
Refer to the API Reference Manualfor how to develop applications.
Step 3: Prepare a manual that explains how to set up the BHT and how to use the applications created.
Step 4: Set up the BHT basic configuration (common settings) by following instructions in this manual.
Step 5: Set up the environment-dependent configuration (such as an IP address).
Step 6: Start operations.

1.3. Usage Precautions
■ Data backup
Non-volatile memory (flash memory) is used to store user data for the BHT. Flash memory has a finite number of
program-erase cycles, therefore frequent access concentrated on the specific memory area may lead to data loss.
To optimize the flash memory usage, the wear leveling function, which automatically distributes data evenly over the
flash memory, is implemented for the BHT. Nevertheless, backing up important data is strongly recommended in order
to prepare for unexpected data loss.
■ Flash memory in consideration of writing lifetime
Flash memory reaches the end of its lifetime as the number of writes increase.
Application development must follow the restrictions listed below in order to prolong the flash memory lifetime.
- Limit the data size written in the flash memory to maximum 100 M bytes per day.
- Limit the write cycles to maximum 5,000 times per day for data smaller than 8 k bytes.
Rechargeable battery
All data including data stored in the BHT RAM, data being edited, and setting information may be lost if the BHT is left
with the drained battery, if the BHT is left for a long period with the battery removed, or if the battery is incorrectly
replaced. By executing the factory reset and Enterprise Reset, all data in the BHT Flash such as file data, and setting
information will be erased. (Refer to 3.6
Resetting to the Factory Default (FactoryReset) and Enterprise reset .)
Therefore, backing up any important data in your PC is strongly recommended.
■ Ensuring stable operations by the periodical resetting
Android may cause memory leaks (insufficient memory) when used over long periods.
Resetting the BHT regularly (power off to on, or Reboot) in the application created (once a day etc.) or as daily routine
is recommended for ensuring stable BHT operation.
For example, call a reset function in the application at the end of daily work or at scheduled update. Refer to the BHT
API Reference Manual for how to program a reset function.

2. Set-up of BHT
This chapter explains how to set up the BHT efficiently and effectively.
2.1. BHT Operations that Delete Data
The data stored in the BHT is deleted after the following operations. In order to ensure stable operations, the BHT must be
set up to restore or recover the deleted data.
