3. Setup Instructions

Follow these steps to set up your Heath Zenith SL-7357 Door Chime Extender.

3.1 Transmitter Installation

Insert Batteries: Open the battery compartment on the back of the transmitter unit. Insert 3 AAA batteries, ensuring correct polarity (+/-). Close the compartment securely.
Position Transmitter: Place the transmitter unit near your existing wired doorbell chime. The microphone on the transmitter needs to be close enough to detect the sound of your doorbell. For optimal performance, position it within 1-2 inches of the chime's sound mechanism (e.g., the bells or bars).
Mount Transmitter: Use the provided double-sided tape or screws from the hardware pack to secure the transmitter in place. Ensure it is stable and its microphone is facing the sound source of your existing doorbell.
Adjust Sensitivity: The transmitter may have a sensitivity adjustment dial or switch. Start with a medium setting and adjust as needed during testing to ensure reliable detection of your doorbell's chime.

3.2 Plug-In Chime Unit Setup

Select Location: Choose a standard wall outlet in the area where you want to hear the extended chime. Ensure this location is within 100 feet (30 meters) of the transmitter for optimal signal reception.
Plug In Chime: Insert the plug-in chime unit into the selected wall outlet.
Select Tune: Locate the tune selection button on the chime unit. Press this button repeatedly to cycle through the 3 available chime tunes until you find your preferred sound.
Adjust Volume: Use the volume control button or dial on the chime unit to set the desired sound level.

3.3 Testing the System

After installing both units, test the system to ensure proper functionality:

Press your existing doorbell button.
Listen for your original doorbell chime.
Simultaneously, the plug-in chime unit should activate and play the selected tune.
If the chime unit does not activate, refer to the Troubleshooting section. You may need to adjust the transmitter's sensitivity or reposition it closer to your existing doorbell.

4. Operating Instructions

Once set up, the Heath Zenith SL-7357 operates automatically. When your existing doorbell rings, the transmitter detects the sound and sends a wireless signal to the plug-in chime unit, which then sounds.

4.1 Changing Chime Tune

To change the chime tune, simply press the tune selection button on the plug-in chime unit. Each press will cycle to the next available tune. Release the button when your desired tune is playing.

4.2 Adjusting Volume

To adjust the volume of the chime, use the volume control button or dial located on the plug-in chime unit. Increase or decrease the volume to your preference.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your door chime extender.

5.1 Battery Replacement (Transmitter)

The transmitter unit requires 3 AAA batteries. Replace these batteries annually or when you notice a decrease in performance or unreliable activation. To replace:

Open the battery compartment on the back of the transmitter.
Remove the old batteries and dispose of them responsibly.
Insert 3 new AAA batteries, observing correct polarity.
Close the battery compartment securely.
Test the system after battery replacement.

5.2 Cleaning

Clean the exterior of both the transmitter and chime units with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the finish or internal components. Ensure no moisture enters the units.
