dretec T-580WTDI Study Timer, Count Up Timer 2, Silent Mode, White

Is there an alarm feature? Such as setting the alarm to wake up at 9AM?

How to turn off and on

Can the start/stop button be set to accumulate time as it's hit? Hit once and it starts, hit again it pauses, hit again continues counting upwards?

Si programo la cuenta regresiva de un minuto y presiono el botón, se reinicia en la programación que puse o solamente se pone en pausa ?
