FAQs
How long does the battery last on a full charge?
Battery life varies significantly based on usage (radio volume, light intensity, charging other devices). Sangean does not specify exact hours but emphasizes its multiple charging options for extended use.
Can I charge the radio while it's playing?
Yes, the MMR-99 can be charged via USB Type-C, solar, or hand crank while it is operating.
What is the IPX55 rating?
IPX55 means the device is protected against dust ingress and is resistant to water jets projected from any direction. It is not fully waterproof.
How many NOAA weather channels are available?
The MMR-99 supports all 7 NOAA weather channels, providing access to weather alerts and forecasts.
What type of USB port is used for charging the radio itself?
The radio is charged using a USB Type-C input port.
Can the hand crank charge the internal battery indefinitely?
The hand crank is primarily for emergency top-ups or trickle charging. Continuous hand-cranking will generate power, but it requires significant effort for substantial charging.
Does the radio have an alarm function?
The product description does not explicitly mention an alarm function, focusing on emergency preparedness and entertainment features.
Troubleshooting
Radio not powering on
Ensure the battery is charged. Try using the hand crank to generate power or charge via USB Type-C. Check that the power button is fully depressed.
Poor radio reception
Extend the telescopic antenna fully. Adjust the antenna's position for better signal. Try tuning to stations using manual tuning if ATS is not optimal. Experiment with the adjustable bandwidth setting.
Device not charging other electronics
Verify that the MMR-99 has sufficient battery charge. Ensure the USB cable is properly connected to both the MMR-99 and the device being charged. Try a different USB cable.
Solar panel not charging effectively
Ensure the solar panel is clean and exposed to direct sunlight. Performance will vary based on sunlight intensity.
Light not functioning
Check the battery level. Ensure the light function is correctly activated according to the manual.
