Connect the supplied USB cable to the DC IN 5V port on the radio and to a USB power adapter (not included) or a computer USB port. The charging indicator will illuminate. A full charge may take several hours.
Note: If the internal battery is completely discharged, the radio may appear unresponsive or cycle on/off. Continue charging until sufficient voltage is restored.
AAA Battery Installation (Optional)
For an alternative power source, you can install 3 AAA batteries (not included) into the compartment on the back of the radio. Ensure correct polarity (+/-) when inserting the batteries.

Powering the Radio
The HRD-905 offers multiple ways to power the unit and charge its internal 10000mAh battery.
| Power Source | Description |
|---|---|
| Internal Lithium-Ion Battery (10000mAh) | The primary rechargeable power source. |
| USB-C Charging (DC IN 5V) | Connect the radio to a USB power source using the provided cable for fastest charging. |
| Solar Panel | Place the radio in direct sunlight to slowly charge the internal battery. This is ideal for maintaining charge or trickle charging. |
| Hand Crank Generator | Rotate the hand crank clockwise or counter-clockwise to generate power and charge the internal battery. A few minutes of cranking can provide power for short periods of radio use or light. |
| 3 x AAA Batteries (Not Included) | Insert into the battery compartment for an additional backup power source. |

Charging External Devices
The HRD-905 can function as a power bank to charge your mobile phone or other small USB-powered devices.
- Ensure the radio's internal battery has sufficient charge.
- Connect your device's USB charging cable to the USB Charging Port (5V 1A) on the side of the radio.
- The radio will begin charging your device.
Note: Charging speed may vary depending on the radio's battery level and the device being charged. Using the hand crank while charging an external device can provide additional power.
Maintenance
- Cleaning: Wipe the radio with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the radio in a cool, dry place when not in use. For long-term storage, ensure the internal battery is partially charged (around 50%) and recharge it every 3-6 months to prolong battery life.
- Battery Care: Avoid fully discharging the internal Lithium-Ion battery frequently. If using AAA batteries, remove them if the radio will not be used for an extended period to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Radio does not turn on or turns off immediately. | Internal battery is completely discharged. | Connect the radio to a USB power source and charge for several hours. Even if it appears unresponsive initially, continue charging. |
| Poor radio reception. | Antenna not extended, weak signal, or interference. | Extend the telescopic antenna fully. Try repositioning the radio. For AM, rotate the radio for best reception. |
| Hand crank or solar charging is slow. | These are supplementary charging methods. | Hand cranking provides power for short-term use. Solar charging is for trickle charging or maintaining battery level. For faster charging, use the USB-C port. |
| Cannot charge external devices. | Radio's internal battery is too low or device requires more power than supplied. | Ensure the radio's internal battery is sufficiently charged. Some high-power devices may not charge optimally. |
| Controls are unresponsive. | Controls are locked. | Briefly press the POWER/LOCK button to unlock the controls. |
