2. Navigate to "Language" using the wheel.
3. Select your desired language to confirm.

4.3. Connecting a Battery

Ensure the battery type and cell count match the charger settings before connecting. Always connect the main battery lead first, then the balance lead.

5. Operating Instructions

5.1. Basic Charging

1. Connect your battery to the appropriate channel (CH1 or CH2) by plugging the main power connector (e.g., XT60) into the battery port and the balance lead into the balance port.
2. Use the 'CH' button to select the desired channel.
3. Press the Speed Shuttle Key to enter task settings.
4. Select 'Charge' as the task type.
5. Choose the correct 'Battery type' (e.g., LiPo, LiHv, NiMH).
6. Set the 'Cell voltage' (e.g., 4.20V for LiPo).
7. Verify the 'Cell count' (the charger often auto-detects this).
8. Adjust the 'Current setting' (charge rate) according to your battery's specifications. A common safe rate is 1C (e.g., 1.8A for an 1800mAh battery).
9. Select 'Start task' to begin charging. The display will show real-time charging status, including individual cell voltages.

5.2. Storage Charging/Discharging

For long-term battery health, it is recommended to store LiPo batteries at a specific voltage (typically 3.80V-3.85V per cell). The HOTA D6 Pro can automatically adjust the battery to this level.

1. Connect your battery as described in section 5.1.
2. Enter task settings and select 'Storage'.
3. The charger will automatically charge or discharge the battery to the preset storage voltage. You can adjust the target storage voltage if needed.
4. Select 'Start task'. The display will indicate 'Storage discharge' or 'Storage charge' as it balances the cells.

5.3. Wireless Charging

The HOTA D6 Pro features a wireless charging pad on its top surface.

Simply place a compatible smartphone (e.g., iPhoneX, iPhone8, Samsung S8) on the charging pad to initiate wireless charging.

5.4. Firmware Upgrade

Keep your charger up-to-date with the latest features and improvements.

Connect the charger to a computer using a Micro USB cable via the update port. Follow the instructions provided by the HOTA firmware update software.
