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 Operator’s Guide or Hardware User’s 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 Manual” for 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.

3.4. Hot Swapping

BHT-1700 and BHT-1800 apply to the “hot swapping” function that enables the battery change without rebooting BHT.

Before using the hot swapping function, be sure to check the followings.

- A new battery must be charged sufficiently.

- A back-up battery must be fully charged.

If the backup battery is not fully charged, when you remove the battery cover, the blue LED and the red LED light up at

the same time (the LED looks purple). In this case, please replace the battery after replacing the battery, attaching the

battery cover, and after the backup battery is fully charged.

Implement the hot swapping in accordance with the following procedure.

[1] If it is not in the suspended state, press the power key for a short time to suspend the BHT.

[2] Remove a battery cover. The screen display becomes OFF and the red LED is turned ON.

[3] Wait until the red LED is turned OFF. (*1)

[4] Change batteries. (*2)

[5] Attach the battery cover.

[6] Press the power key to resume the BHT.

− Note −

The hot swapping function cannot be used in 3 minutes after the power is ON.

– Point –

(*1) If the red LED is not turned OFF even if you wait for more than 60 seconds, attach the battery

cover without changing batteries. Implement the hot swapping later.

(*2) The state when the hot swapping can be implemented is kept for 1 minutes after the battery is

removed with the back-up battery fully charged. If a battery is changed after 1 minutes or more

have passed or when the back-up battery is not fully charged, the hot swapping may be failed. In

this case, the power will be OFF (in the shutdown state) and the BHT will reboot next time the

power key is pressed.
