Frequently Asked Questions - FR-A25 Sunstech
How do I turn on the radio?
Turn the volume/power knob clockwise until you hear a click. Adjust volume as needed.
How do I switch between AM and FM?
Use the AM/FM band switch located on the top or side of the radio to select the desired band.
Why is the reception poor?
For FM, fully extend the telescopic antenna and adjust its position. For AM, rotate the entire radio to improve the internal ferrite antenna orientation.
What type of batteries does it use?
It requires 2 AA batteries (1.5V each). Alkaline or rechargeable Ni-MH can be used.
Can I use an AC adapter?
Yes, but an AC adapter is not included. Use a 3V DC adapter with a compatible plug (positive tip).
How do I clean the radio?
Wipe the exterior with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners.
Is there a headphone output?
Yes, a 3.5mm stereo headphone jack is located on the side. Inserting headphones disables the built-in speaker.
Why is there static or noise?
Static may occur due to weak signal. Try adjusting the antenna or moving the radio to a different location. Interference from electronic devices can also cause noise.
How do I replace the batteries?
Open the battery compartment on the back, remove old batteries, insert new AA batteries following polarity markings (+/-), and close the compartment.
The radio does not turn on. What should I do?
Check that batteries are inserted correctly and are fresh. If using an AC adapter, ensure it is properly connected and providing power. If still not working, contact Sunstech support.
