COMPLETE AZAN (for all cities around the world): A high quality digital Azan sound for all prayers (including complete Fajr azan) can be played. With azan volume control fitted in all clock models. Azan times are calculated accurately for all cities around the world. ALFAJR uses the local taqweem or the most widely used taqweem system for your city. Other standard taqweem systems are available. AUTOMATIC FAJR ALARM: This unique feature allows you to wake up everyday exactly at the same time relative to Fajr azan. For example, suppose you set the alarm to 5:15 AM and the Fajr azan is at 5:00 AM. On the next day, if Fajr azan becomes 5:01 AM, then automatically this alarm will change to 5:16 AM. In this case, you will wake up 15 minutes after Fajr azan everyday.
