5. Operating Instructions

The EXTEL diBi Flash Wireless Doorbell is designed for simple operation.

5.1. Ringtone Selection

The receiver unit offers 6 distinct ringtones. To change the ringtone:

• Locate the music note button (♫) on the top of the receiver unit.
• Press this button repeatedly to cycle through the available ringtones. Stop when you hear your preferred melody.

If you have multiple transmitters, you can customize a unique ringtone for each to easily distinguish which entrance a visitor is at.

5.2. Volume Adjustment

To adjust the volume of the doorbell chime:

• Locate the volume button (speaker icon with sound waves) on the top of the receiver unit.
• Press this button to cycle through the available volume levels (e.g., high, medium, low, mute).

5.3. Flash Function

In addition to the audible chime, the flash bell receiver is equipped with a visual alert. When the call button is pressed, the receiver will emit a white flash light, providing an additional notification, especially useful in noisy environments or for individuals with hearing impairments.

5.4. Low Power Alert

The system includes a low power alert feature. When the batteries in either the call button or the flash bell receiver are running low, the unit will provide an indication (e.g., a specific light pattern or sound) to inform you that battery replacement is needed. This ensures continuous operation and prevents missed visitors.
