quarterly periodic reminder

This is a quarterly periodic reminder, 90 days countdown timer with two keys. Good for quarterly reminding of periodic works, like medication; treatment; oil change; car inspection; maintenance; meeting; filter cartridge , UV lamp, key parts replacement; healthy checking; farming activity; and etc... Press the key at left to start or stop counting. Press the right one to set back to default value, 90 days. There are two ways of endless alert when time's up:

---- Endless Visual Alert: Full LCD display blinking always
---- Audible Alert: So called PSEA (Power Saving Endless Alert) endless alarm, i.e., beep 6 times then wait for 10 seconds, and repeat again

The LCD display pattern will be changed automatically to appropriate format during counting as: DD:HH --> HH:MM --> MM:SS. 1 second is the minimum resolution when countdown under one minute.

Thanks for our strictly QC control of power consumption in production line, more than 95% of battery power still remained after the first cycle of 90 days countdown to zero. The original installed battery is possible to last for 10 years without replacing new battery if aural alert is not activated and aging issue is not considered. Therefore, in order to save power for long term running, please try to stop the alert as soon as possible after countdown to zero.
