Grundig Audio Players & Recorders - Recent Questions, Troubleshooting & Support

I think this unit uses 'UM-1' batteries. They are also known as 'D Cell', 'R20' or 'LR20' batteries. Most good electrical, hardware and some of the larger 'supermarket' stores will have these batteries available. A good quality brand like Duracell or Varta should do the job. There is also two separate smaller 'button' batteries in the unit used to power the clock.

Question edited for clarity. This is the only mention With the radio turned on or off, press the ALARM button with quick, short presses, over and over, noticing that a speaker or a bell appears under the box labeled 'Timer' in the upper left corner of the display. Leave the speaker there if you want the speaker alarm to turn the radio on; leave the bell if you want to wake up to a beeper. Leave it blank, with no speaker or bell if you do not want the alarm. Sometimes a beep when off is telling you that it is one standby or it is telling you the battery is becoming depleted. https://www.manualslib.com/manual/624477/Grundig-Traveler-Ii-Digital-G8.html#manual There is a beep on button press https://www.google.com/search?q=Grundig+8+traveller+II+digital+intermittent+beep ..

Hi Carlie, I apologize, however I am not familiar with the code requirement for Grundig Radio. I recommend that you contact the dealership directly and they should be able to help you.

Question moved from Mini (the car). Take it apart and look at the main board for dry joints on components. It is a known issue https://www.google.com/search?q=Grundig+Eton+mini+radio+turns+off+after+a+few+seconds ..

Question edited for 'make model (what it is). Question moved form Cars and Trucks to Grundig S350. It will need aerials connecting to it as it is a receiver.. https://www.google.com/search?q=Grundig+S350 ..

Rubbing 70-90% alcohol applied on a piece of cloth then spread on the radio will eliminate the sticky substance. May need several application and vigorous rubbing. After the process, my Grundig G8 Traveller II looks better than the original rubbery texture. Cleaner too.

Try moving it to another location to test the antenna strength. It sounds like it is picking up interference. https://www.google.com/search?q=grundig+satellit+800+am+antenna ..

WWV transmits on MHZ and not KHZ 5 10 and 15 and lower power on 2.5 and 20 MHZ. Depending on where you are, the antenna might no be enough to bring in the signal. You should use an external antenna for serious reception.

WD40 IS NOT A CONTACT CLEANER

On the rear where the power adapter plugs in, it should show in input voltage and polarity. Check the power supply output voltage with a volt meter. Generally, it is the sum total of all the batteries, so it if takes 4xAA @1.5 volt batteries the voltage would be 6 volts DC. It sounds like it is faulty.

Take it to an authorised Grundig Servicentre for repair otherwise it may never work again.

I had similar problem with my S350. It was a component which had failed. I found a place that fixed it at a reasonable cost. It is ACT Electronics in Long Beach, CA. I don't have phone number but you can google it. It is run by a person from India. You send him the radio with a $30 check. He then assesses what is wrong, gives you a price to fix it, send him a check, then he fixes and sends you the radio. He did a fine job for me. Good luck!

It's lowest operating frequency should be 100 kHz, unless it has been altered. What you would hear below 100 kHz is a mystery.
