As people know the most important feature of a timer is constantly reminding user that the set time is up, especially counting for long term period. People may disregard the case. But audible alarm wastes too much power. To continually keeping piezo buzzer goes off, the battery power should be exhausted for just few minutes. In order to make this feature comes realistic, our R/D developed a new program called PSEA (power saving endless alert) for the alarm. This model is equipped with this PSEA feature as a standard. However, if people prefer to has traditional one minute alert, it can be down too.

Further to the PSEA alert, like mentioned above, the timer provides another method of endless alert, called visual endless alert, i.e., when counting expired, as well as audible alert, the full LCD becomes blinking. So this timer provides dual alert, audible and visual.

The display resolution is dynamically changed, from 1 day down to 1 second depending upon the counting stage. Due to the limitation of 4 digits LCD screen, with constant resolution the display cannot show the counting details after counting down to 100 days. Usually most of the product available in market, the display shows day reading only. User cannot see the hour reading. But this timer provides the solution. It changes the display format dynamically from DDDD to DD:HH, DD:HH to HH:MM, and then from HH:MM to MM:SS.

Furthermore, the "count up" feature is added as a standard to provide user to know how long the time is expired. With this feature, user can use the timer as a chronometer too. It can count up from 0 to 9999 days. Indeed it is an ideal instrument to measure long term activities, or lifespan.
