quarterly periodic reminder

Product Descriptions
This is a quarterly periodic reminding device, 90 days pre-programmed countdown timer with single key operation. Good for 90 days periodic reminding, like medication, body treatment, meeting, filter, cartridge, UV lamp, or key part replacement, healthy checking, oil change, machine inspection, maintenance, and, ... etc.. Press the single key to initiate the reminder to 90 days and countdown right away. 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, with significant power saving during audible alarm, i.e., beep 6 times then wait for 10 seconds, and repeat again

The LCD display pattern will be changed automatically to the 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 the battery 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.
