Setting date and time on a Hitachi RAR-3U3 split system controller

I replaced the batteries. I pushed the reset button. I get a flashing Time button, but when I press it nothing happens. If I then go on to press the Timer Control button all that happens is that the temp of +/-1 or +/-2 shows (ie. like you are changing temps on the Auto setting).

SOURCE: Camera looses date & time setting

There is a cmos battery (or a memory battery) on the main circuit that like any battery wears out eventually. If you are familiar with repairing electronic circuits you can get the part from Olympus. There is no part number just "memory battery for C-740" will suffice. Your other two choices are to take the camera to a shop where they can do the kob for you. Don't let them sell you a complete new board, you don't need one. Not for this problem anyway. Or you can ignore the problem and reset the camera (or not)each time you change batteries.

SOURCE: Digital Control (for oven temp and clock adjustment) not working

Puzzeled, usually when there is a stuck or shorted keypad there will be an error code. First let's see if we can tell if we are in Centigrade or Ferenhiet. Press the bake and broil button together for 2 or 3 seconds. SF should appear in the display. Press the broil pad again and C or F will be displayed. Toggle to F and press start. See if that was the problem. If not try to increase the speed of the + and - keypads. Press bake and broil together for 2 seconds until SF displays. Press the + keypad increase the speed of the control. It should toggle from 1 to 5, 5 being the fastest. Press start and see if that works. If niether works..then have someone remove the keypad ribbon cable from the control board and clean the ends with an eraser. See if that solves the back and let me know.

No setting instructions.

Atomic clocks are the wave of the future because of their precision. While it takes a scientist to fully understand how these clocks actually work, the general public is primarily interested in their accuracy, rather than their construction. A major benefit to atomic clocks is that they serve as the main standard for calculating time internationally. While each version of atomic clock may have minor differences, for the most part, they are set in the same way.

1. Remove the battery cover on the back of the clock using the correct screwdriver (if one is required). Be careful not to break the cover or lose any screws in the process. Insert the required number and type of batteries into the clock. Most atomic clocks take two AA batteries. Make sure the batteries are positioned with the right polarity in place, and that the clock is functioning, before replacing the battery cover. Place the cover back into its original position and screw any necessary pieces back into place to secure the cover and protect the batteries from springing free.

2. Enter the program mode of the clock by holding down the appropriate button. In most cases, the button will be clearly marked "Set." If not, refer to the clock's instructions to find out which button fulfills that function.

3. Push the button down until the clock flashes its default time zone setting of --5EST. It is now ready to program each function separately as described in the steps below. If for some reason the clock does not respond as outlined, refer to the instructions provided with it for troubleshooting guidance.

4. Press the + button to select the right time zone from the 13 international options provided. The default setting of --5EST (Eastern Time), should appear first, followed by --6 CST (Central Time), -7MST (Mountain Time), -8PST (Pacific Time), -9ALA (Alaskan Time), -10HAW (Hawaiian Time), -11, -12, GMT (Greenwich Mean Time), -1, -2, -3 and --4ATL (Atlantic Time). Then push the "Set" button down again to confirm the time-zone setting you have chosen. Push down the "Set" button again and hold until the selected time zone flashes.

5. Press the "Set" button down two more times to establish the default language setting. Press the + button down to select English, French or Spanish. Then push the "Set" button down again to confirm the language setting.

6. Push down the "Set" button again and hold it until the time zone flashes. Then press the button down three more times until the time 12:00 flashes. Press the + button down to select the hour at the time of the clock's setting. Make sure the hour is set appropriately to AM or PM. Then push the "Set" button down once more to confirm the hour setting.

7. Push the "Set" button again and hold until the time zone flashes. Then press the "Set" button four more times until 00 flashes. Press the + button down again to select the minutes at the moment of setting. Push the "Set" button once more to confirm the minute setting.

8. Push the "Set" button again and hold until the time zone flashes. Then press the "Set" button five more times until the default year flashes. Press the + button down. Toggle through the settings until the appropriate year is reached. Then press the "Set" button down to confirm the year.

9. Push the "Set" button again and hold until the time zone flashes. Then press the "Set" button six more times until the default month of January is reached. Toggle through until you reach the right month. Then press the "Set" button down to confirm the month.

10. Push the "Set" button again and hold until the time zone flashes. Then press the "Set" button seven more times until the default date of 1 is reached. Toggle through until you reach the right date. Then press the "Set" button down to confirm the date.

11. Push the "Set" button again and hold until the time zone flashes. Then press the "Set" button eight more times until the default setting of Sunday is found. Toggle through until you reach the right weekday. Then press the "Set" button down to confirm the weekday.

Hope this wishes.

Wii fit board wont sync

Ok I feel a little silly, there is a sync button on the console (inside the flap by the power on button) and the board (inside the battery compartment on the underside of the board) as soon as I pressed them at the same time it worked. Goodluck everyone.

Accuwave DS Clock

The radio may not be able to get a strong enough or clear enough signal to process (night is best away from TV, computers and radios).  To regain "control" of the clock, take the battery out, wait 30 seconds and then reinstall it.  This will reset the clock.  You can then manually set the clock. 
Press SET for a few seconds until the hour starts flashing in the display.  Then press the ADJUST button to set the hour.  Press SET to move to the different functions (Hour -> Minutes -> Seconds-> Month -> Date -> Year) each time using the ADJUST button to correct the setting.  Finally press MODE to exit the setting mode.  
If the time zone is incorrect for your area (default is PST), press MODE to enter the Alarm Time Mode; then press SET to flip through the time zones; then press MODE again to exit.
The little "reset" is for use if the LCD display doesn't come on when the battery is changed. It doesn't affect any of the clock settings per se.

Keyboard not responding

Solution. My wireles keyboard stopped working except for the F-Lock key, the Media key and the sleep key. It wasn't batteries, even though I tried, communication was there because the above keys were working. Remove the batteries from your keyboard and let it sit for about 10 minutes. Press the red connect button a few times and other various keys every few minutes during that time. This may be the whole "capacitor discharge" trick, but I tired that with someone elses instructions and my keyboard did not work after 2 minutes of key pressing. I think it just needed more time to clear out the secure settings. Good luck, I was about to trash this keyboard until I tried again
