There are basically three types of electronic clock.
Quite old-fashioned are those that use the frequency of the mains electricity it is plugged into as a means of approximately keeping time. For practical purposes this type is more accurate than most mechanical types but may lose or gain a little and need adjusting from time-to-time.
If this type becomes unreliable there is nothing the user can do about it and an engineer would be needed or perhaps the garbage or recycling would be a better place.
The second type is the now very common quartz type where the clock circuitry keeps time by being triggered by a very accurate quartz crystal oscillator.
These types are generally so accurate it is worth providing battery back-up in case of power failure as well as preserving alarm and reminder settings.
If this type becomes inaccurate it indicates a problem with the circuitry and again recycling is probably the most practical option, though accumulated damp and dust inside can affect the delicate circuitry which might be restored to accuracy after a thorough internal clean.
I once had similar trouble with my clock radio which was caused in this instance by me forgetting how to operate it correctly. Spending a half-hour playing around with it refreshed my memory so in future I will remember when I have set the alarm to return the display to the clock.
The third type of clock is the radio controlled type that is set and keeps time by receiving a radio signal from a national atomic clock. They can do strange or unusual things if the signal is not being received properly or the clock is faulty but there is usually a function for setting the time manually though in my limited experience these aren't clocks for everyone and they aren't suitable for every location.
Sounds like the original problem which is not truly a problem is that the Adaptive Recovery Setting was set to on which the Thermostat is self learning and if for example you set the thermostat to go to 70 deg. at a certain time it will turn the unit on early to achieve that setting at your designated time, and it will slowly learn and adapt itself to how long it takes to reach that setting from the previous setting. The next issue is that you have actually accessed the installer's settings page and you will need your manual to get out of this.
If your unit is a wireless keyboard only, then there is a button on the bottom of the keyboard and another on the receiver that is plugged into the usb port of the computer. In order to calibrate the system when it looses its signal, you have to press and hold both buttons down at the same time for 30 to 45 seconds. That means press the button the receiver and the button on the bottom of the keyboard at the same time and hold them down for 30 to 45 seconds. This will revive the signal and bring it back to working condition.
If your unit is a wireless mouse and wireless keyboard then there are probably 3 buttons involved that need to be pressed and held for 30 to 45 seconds at the same time. One button on the mouse, one on the keyboard and the last on the receiver.
If you press and hold the buttons down as explained above, it will correct the problem.
"To enter time/date setting format on the keyboard LCD, press the FN key and F10 key simultaneously."
"LCD: Mode (F9): switch mode from Time/Date to Alarm to Timer to Character Count. Set (F10): press to set Time/Date, Alarm and Timer. Change batteries one by one to keep LCD settings. Remove the 4 keyboard batteries to reset Character Count to "o." Bell (f11): put Alarm On or Off. START/STOP (F12): start 01 pause Timer."
The Logitech program group (should be on your Start menu) will give you
further information for identifying keys, and for formatting the
keyboard and mouse.
Your headphone mic is all right. The problem is with the sound driver you are using. Many a time the headphone jack are not properly connected so it may be another issue for not working of your headphone. Your operating system is all right check out the sound driver setting from the control panel. Good Luck
How much memory do you have installed in your
computer? It may need to be, increased, as this is likely to be the cause
of your computer freezing, rebooting, times out, or shutting down.
Hope this is of some help. Bud
What's the title and exact message again? It sounds like something went haywire in that program's settings; make a backup of them (or rename the files) and make a new settings file, or reinstall the program. Fixed?
