Why do I hear no sound or poor sound from the device?
Answer
Check that the sound volume is adjusted to an audible level by turning the VOLUME/POWER OFF knob on the device.
Headphones are connected to the device. Remove them and adjust the sound volume.
The FM aerial is not fully extended. Fully extend it to get the best reception.
The headphones are not fully inserted and are causing humming or sound distortion. Check that the headphones are fully inserted into the headphone jack on the device.
