OFFPairing□ Turn on the Bluetooth function of connection device and power on the scale. Select the “A&D_HID” device and pair.
S/N may have been added after “A&D_HID”.
□ You will not be able to connect if more than 30 seconds have passed without pairing after selecting the device.
In that case, power off the scale and try again.

6. Precautions for Use□ Refer to the instruction manual of the connection device for the pairing.
□ The LED lights up when the wireless communication connection is completed.
□ It will connect automatically when the paired device is nearby. When connecting to other device, turn off the unused devices
or disconnect.
□ If you can’t communicate, check that the connector is firmly connected. If it still fails, check the scale settings, pairing andconnected devices.

□ Bluetooth devices is EC2832 (KAGA ELECTRONICS Co., Ltd.)/ Bluetooth 5.0 (Bluetooth® Low Energy)□ The effective range communication is 10 m or less in an unobstructed space.
If there is an obstacle such as a wall, the range of communication will be shorter.
□ Interference may be caused near the following devices that use the 2.4 GHz frequency band, which is the same as forBluetooth. Therefore, this device is not suited for uses that require reliability.
- Wireless LAN- Bluetooth devices (such as mobile phones)- Home appliances such as microwave ovens

8. Compliance

Note: To switch the DIP switch settings, use a rounded object such as the tip of a ballpoint pen to slide it.

SELECT□ By turning on DIP switch No.1, you can connect to a Smartphone, tablet, or PC with Bluetooth and use a general-purpose
text application or spreadsheet software.
□ The output data has no header (ST, WT, etc.), + sign and unit (g, kg, etc.).
□ Set the keyboard language of device to English.
