Frequently Asked Questions - SRF-M85W SONY
How do I set a preset station on the SRF-M85W?
Tune to the desired station, then press and hold one of the preset buttons (1-5) until the display confirms the setting. To save more than 5 presets, use the memory button to cycle through banks.
Can I use rechargeable batteries in this radio?
Yes, the radio can use Ni-MH rechargeable AA batteries. However, battery life may be shorter than with alkaline batteries.
Why is there no sound from the speaker when I plug in earphones?
Plugging in earphones automatically mutes the built-in speaker. Remove the earphone plug to use the speaker again.
How can I improve FM reception?
Extend the telescopic antenna fully and adjust its angle for best signal. Avoid metal objects near the antenna.
What is the sleep timer feature and how do I use it?
The sleep timer automatically turns off the radio after a set time. Press the SLEEP button repeatedly to select 60, 30, or 15 minutes.
How do I lock the buttons to prevent accidental operation?
Slide the HOLD switch on the side of the radio to the 'HOLD' position. The key lock indicator will appear on the display.
The display shows 'STEREO' but I only hear mono. Why?
If the FM signal is weak, the radio automatically switches to mono mode to reduce noise. Try adjusting the antenna for better reception.
How often should I replace the batteries?
Battery life is approximately 40 hours with alkaline batteries. Replace them when the display dims or the sound weakens.
Can I use this radio while charging batteries?
No, the radio does not support in-unit charging. Remove rechargeable batteries and charge them in an external charger.
Does the radio have a volume control tone setting?
Yes, the volume control is a rotary knob. There is no separate tone control; the sound is designed for clear speech and music.
