I HAVE A MODEL #ONB13AV001 CLOCK RADIO HOW DO I SET IT UP

Can you comment with the model number? It will be on the information sticker on the radio itself. It will possibly start with 'CRX-'.
Try this - Press and hold the alarm set button until the display flashes like your setting the alarm time. Click the same button again and it should swap between buzzer and radio each time you click it. It will probably show some sort of logo on the display telling you which it is set to.

What manufacturer and model model Onyx clock radio...?

Generally, you hold the "set" button down, then press the "hour" button to set the hour, then press the "minute" button to set the minutes on clock radios.

Hello
Get into this link. You can get all the details for your clock radio from there.
lib.store.yahoo.net/lib/partshelf/Acu-Rite-00592W-Manual.

The nature of this type of clock is that you neither can nor need to set it manually. Your only input is the time zone and it will look for the radio set signal from Colorado. That model does not get any hits on Google. Who makes it?

SELL! SELL! SELL! Yup the clock has bit the dust sell er and cut your losses.

For this model Clock radio you will have to call Emerson Customer support at this telephone number.1-800-909-1240 between the hours of 8am-4:30pm CT. Tell them the make and model number of your Clock/Radio and ask them for assistance. You will probably be told that,your Clock/Radio has no updating feature. This is because at that time there was no need for such a feature. The best way to get the new features is to buy a new Clock/Radio. Thank you for using FixYA and have a nice day.

I emailed the company and they sent a pdf of the manual back the same day.

For the Clock/Radios that are having problems with the clock display and settings. You will have to reset the Clock/Radio's microprocessor. To do this you must unplug the Clock/Radio from the wall outlet and remove the internal battery. You must let the Clock/Radio set with no power for at least 1 hour to discharge the microprocessor circuits. The microprocessor should then be able to reset itself. You can then reinsert the battery and plug the Clock/Radio into the a/c wall outlet. The functions should have reset and be working normally. If this does not solve the problem, try putting in a new battery (CR2430). Before putting in the new battery, unplug the clock radio and remove the old battery and let it set again for a few hours this time to try to reset the microprocessor. If this does not solve the problem (This includes the person with the complete Clock/Radio operation failure) you can call the Emerson customer support at this telephone number 1-800-898-9020. Give them the make and model number of the Clock/Radio. Tell them the problems you are having with the operation of the Clock/Radio and ask them for assistance. I hope this information helps you solve the problems your are having with your Clock/ Radios.
