Proper Care of the BHT

Make sure to turn OFF the BHT before cleaning. Terminal dirt on the BHT and battery

Periodically wipe any dirt from the terminals of the BHT and battery with a cotton swab or similar soft object. Be sure not to scratch or deform the terminals while cleaning.
Never use organic solvents such as thinner or alcohol, as this may cause terminal plating to be peeled off.

Housing dirt

Wipe any dirt from the housing with a dry, soft cloth.
If excessively dirty, wipe with a soft cloth that has been soaked in soapy water (always use a neutral detergent) and wrung out thoroughly.
Never use organic solvents such as thinner or alcohol, as this may cause the housing to be marred or paint to be peeled off.

LCD screen dirt
Never rub or strike the LCD screen with anything hard, as this may result in scratches on the screen or breakage.

Code reading window dirt
Any dirt or dust adhering to the clear plate of the code reading window will adversely affect reading performance.
When using in dusty areas, check regularly whether any dust has accumulated on the clear plate of the code reading window, and if so, first blow the dust away with an airbrush, and then gently wipe the plate with a cotton swab or similar soft object.
If sand or hard particles have accumulated, rubbing the plate will result in scratches. Blow the particles away with an airbrush or wipe with a soft brush.

Preparation before use

Fasten the wrist strap.

Fasten the wrist strap to the BHT-M80 as shown on the right.

Inserting and removing the main battery

Insert the battery in the arrow direction.
Push the battery in the arrow direction.
Push the battery cover locks in the arrow direction
Pull out the battery with the battery tab held.

Charging the BHT

The main battery may not be fully charged for shipment. Please charge the main battery to full before using the handy terminal. You may use the Charging Cradle or USB cable to charge the handy terminal.

Charging Time

Main battery

The main battery powers the handy terminal to work. It takes approximately 3 hours to charge an empty main battery to full. The status indicator above the screen will light up in red while charging and will turn green when charging is complete.

Sub-battery
The sub-battery is mounted on the main board and used for retaining data when the battery is replaced or when it is removed.
When the sub-battery is fully charged, data can be retained for at least five minutes.
It may take approximately ten minutes to fully charge an empty sub-battery after installing the main one. Do not remove the battery so as to retain data properly.

Charging Temperature
Charging the battery at room temperature (18 °C to 25 °C) is recommended in order to deliver optimal performance. Please note that battery charging stops when ambient temperature drops below 0°C or exceeds 40°C. The temperature to stop charging may vary according to the practical operating environment.

Operation on Battery Power
When 802.11a/b/g/n/ac, GSM/GPRS/EDGE/WCDMA/UMTS/HSDPA/HSUPA/HSPA+/LTE, Bluetooth v5.1&v2.1+EDR and GPS are all enabled on battery power, the main battery level will drop down substantially. Prolonged use of the display and continued scanning of barcodes will also affect battery level.
In order to avoid the unexpected system shutting down when the battery level is low, we suggest that you keep a fresh battery for replacement at all times, or connect the BHT to external power.

Remove the battery from the BHT or the Cradle then store in a cool and dry place if not using the BHT for an extended period of time.
Storing a fully charged or depleted (unable to turn on the BHT) battery for long periods of time may deteriorate the performance and life of the battery.
For long-term storage, storing the battery at 50% of the power level is recommended.
During long-term storage, charge the battery cartridge fully once a year in order to maintain the battery performance. When fully charge, allow the battery to discharge down to the recommended level before restoring.
The battery may swell over the years depending on the usage environment. This is a characteristic of a lithium-ion battery and is not safety hazard.

Charging Status of the BHT
The Charge status of the BHT is shown on the status indicator above the display screen.

Terminal-FIG-10

Notice on the power connection of the charging cradle
As for CU-M80U with the USB interface, both the power adapter and the USB cable can be used.
To charge both BHT and the spare battery, use the power adapter.
When charging with the USB cable, only BHT can be charged. Under the conditions, such as when the large capacity battery is installed in the BHT or when the BHT is under operation while charging, the use of the power adapter is recommended because these conditions may result in long-time charging or a charging error. Using a deteriorated battery may cause a charging error. In this case, replace the battery with the new one.
