How can I increase the volume of the radio

Check the "settings". You may have it set so the volume buttons only adjust the beeps. I've seen this happen on a couple of different units.

Those units dont have a lot of adjustments in them. If cleaning the contacts as advised does not help, you could have any one of a dozen issues that cannot be repaired by you and is not worth the money to fix.

Hello,

I believe the ringer volume is low or at minimal or turned off, that's why the ring is very low. Try this; press the arrow (left and right or up and down button) on the phone constantly. This should increase the ring volume if actually it is low. Or, call the phone with another line, while the phone is ringing and press the arrow buttons without picking up the phone, this should increase the volume.

If the above doesn't solve the problem, please let me know so that I may direct you further.

Good luck.

or follow instruction

1. Press the SET button until WAKE 1 / WAKE 2 icon is blinking.

3. After the WAKE time is set, press SET repeatedly until no icon is blinking.

Tips:

• The unit equips with GRADU- WAKE feature, the alarm tone volume will increase gradually to its maximum in about 30 to 45 seconds.
• If you set the SLEEP function with low volume level before going to bed, we advise using WAKE mode to wake you up since its volume will automatically increase.

You can select your CD wake track by the following procedures:

2. While holding WAKE UP CD TRACK, press REV or FWD to select your desired CD wake up track.

Did swapping the batteries produce normal volume from the previously low volume radio?

It does seem like it is a battery problem. These days no household should be without a decent battery tester...

Try cleaning iPhone with elec. Cleaner
basically your mesh is real dirty

It could be a safety protection meaning you could have a shorted speaker check all speakers and wiring, or it could be a defective volume control, try cleaning the volume with a contact cleaner spray you can find at any good electronic store (you normally have to open the radio to reach the POTENTIOMETER/VOLUME) to be able to spray inside it, than alternate (high/low) the control repetively to move/clean the volume's circuitry

Good luck!

its a new one so change it its a cell phone problem

If you are talking about a new from the factory radio, there is no way to increase volume. If you are talking about an existing radio which has lost volume over time, short of cleaning the grill of debris, and using a known good battery, there is no fix for low receive audio.

install sigmatel audio driver and it will increase ur vol
