After long term counting, some people do not like to hear noisy alarm especially in a peaceful and quite atmosphere. Therefore VOSCA developed the reminder with LED blinking as an alert mean. When counting expired, the high intensity LED lamp blinking once every second for 6 times and keep quiet for 10 seconds, and then repeat the same blinking cycle forever until the battery power exhausted.
This round shape LED blinking reminder, measured 40 mm diameter and 14 mm thickness, with adhesive tape on the back cover providing user to stick it on anywhere needed conveniently. Powered with 2 pieces of LR44 button cell, and isolated by a PVC tab before use. People just peel off the tab to activate the timer to start countdown from certain pre-programed time, available in 365 days, 300 days, 180 days, 90 days, 60 days, 30 days, or more for various application.
When countdown expired, as well as LED blinking, the full LCD display blinking too. The LCD display automatically changes to appropriate format during counting down: DD:HH --> HH:MM --> MM:SS. 1 second is the minimum resolution when countdown under one minute.
This reminder is designed to reminding people that the lifespan of UV lamp, water filter, or air filter is expired and new one should be replaced. It is also good to remind personal body treatment, piano annual tuning, healthy checking, oil change, machine or car routing inspection, equipment maintenance, and, ... etc..
