It would need to be opened up to remove any salts or other things in the water. If the toilet water contained any flush additives they could have attacked the internal parts. In which case I think it would become very costly to repair. If it is just a case of stuff causing a short circuit, then a clean and dry should solve it.

Take the battery out and stick it into a bin (or bag) of uncooked rice for 24 to 48 hours; this should draw out any moisture in the unit. If that doesn't fix it consider looking for a new one.

only by replacement but then again the cost would be worth more than a new unit

Here's a link to the eton site where you can download and print the manual for your radio. Instructions for the alarm function are on page 7:

Spray some WD-40 on the on/off button and press and release the button multiple times. This will clean the gunk built up on the micro-switch and make a better connection.

Replacement is possible, the back of the radio needs to come off and there is a screw at the bottom of the antenna. Remove this and the old one will slide out and simple to install new one. Call Eton for replacement, can be foung with a google search....

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 ..

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 ..
