How can I turn the hourly chime off for the Adidas adp1647 digital watch?

It seems that most 4 button electronic watches have similar directions. There should be four buttons. Clockwise from top left is the Light button, followed by S2 (Stop), S1 (Reset) and finally on the lower left S3 (Mode). Who knows why they are numbered this way. To set hourly chime Hold down S1 and press S3. When all 7 day flags show the chime is on. When they are off the chime is off. To set the alarm hold down S1 and press S2. Alarm icon will display or go off. Release S1 button and display will return to normal time. Hope this works for your watch

Generally the chime is turned on or off by pressing a combination of two buttons. If you don't have the instructions that came with the watch, then perhaps you can figure it out with a little trial and error. On watches similar to yours, pressing two buttons at once changes functions such as 12/24 hour time, turning the alarm or chime on/off, switching the day/month in the date display (ie. 12-6 to 6-12), etc. You will just have to figure out which combination turns the chime on and off.

When you are setting alarm, look for the tiny speaker or volume sign on the so called dial. You must push appropriate buttons till that sign disappears. Then the beep will go off.

The EL in Auto EL stands for Electroluminescence and is basically a fancy way to say backlight.

The website above www.adidas.com/campaigns/watches_fw07/content/index.asp? is the only place I have found to find instruction manuals from adidas

You can get instructions from their web site (www.adidas.com/campaigns/watches_fw07/content/index.asp?)

Click on "instruction manuals" in the menu on the left, choose your country.

You will be presented with a series of generic instructions from which you should choose the ones that suit your watch.

Your watch has buttons refered to as A,B,C,D.

A is top left, B is lower left, C is top right and D is bottom right.

To set the watch press A and hold until the chime begins to flash.
press C or D to adjust the hour.
press B to advance to the next setting, using C&D again,
continie to press B to adjust other settings or press A to save new settings and exit setting mode.
