The accuracy of the Fajr prayer time is critical, as it marks the onset of the daily fast during Ramadan and the first prayer of the day. The Al-Fajr clock series (including models Fajr-1, Fajr Pro, and Digital Dual-Display) operates on pre-programmed astronomical algorithms. However, user error in setting the device leads to a phenomenon known as "Azan drift," where the call occurs several minutes before or after the correct local time.
Setting the azan time on an is a multi-step process that involves establishing your geographic location to enable automatic calculations or manually fine-tuning specific prayer times for accuracy. Since these clocks use a Taqweem system based on your city’s coordinates, getting the location right is the most critical step for synchronization. 1. Setting Your City for Automatic Azan Calculation
| Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | Fajr Azan rings 20 min too early | Incorrect calculation angle (e.g., 15° instead of 18°) | Change ANGLE setting from 15 to 18 or 19 | | Fajr Azan rings 10 min too late | DST is ON (clock is artificially +1 hour) | Turn DST to OFF and manually adjust time | | Asr time is wrong but Fajr is correct | Asr method set to Hanafi vs Standard | Navigate to ASR menu; change from HANAFI to STANDARD | | Clock resets after power outage | No backup batteries | Install 2x AA batteries (backup) before setting time | | Azan does not play at Fajr time | Silent mode enabled or volume zero | Check volume dial; disable QUIET mode in settings |
This is the most important step. Check the label on the back of your clock or the user manual for a list of codes.

Setting the Azan time on an Al-Fajr clock is not a simple "set and forget" operation. It requires a deliberate configuration of three interdependent layers: (DST off), geolocation (city or coordinates), and astronomical angle (18° vs 19.5°). The most common error—incorrect Fajr timing—is almost always resolved by adjusting the calculation angle rather than shifting the clock’s hour hand. Users are advised to verify their settings against a local mosque’s published timetable for three consecutive days to validate the configuration.
