Setup
1. Install Transmitter Battery
The CR2450 lithium battery is typically pre-installed in the ERA-PBTX push button transmitter. To access the battery compartment or replace the battery:
- Carefully insert a small flat-head screwdriver (provided) into the small notch on the side of the transmitter to gently pry open the front cover.
- Ensure the CR2450 battery is correctly seated with the positive (+) side facing up.
- Snap the front cover back onto the transmitter.

2. Pair Transmitter with Receiver
To ensure the transmitter and receiver communicate correctly, they must be paired:
- Plug the ERA-RXPG receiver into a standard electrical outlet. The receiver will emit a short beep and its LED light will flash.
- On the side of the receiver, locate the mode switch. Select your desired alert mode (melody only, strobe only, or melody + strobe).
- Press the push button on the ERA-PBTX transmitter. The receiver should respond with the selected alert (melody, strobe, or both). This confirms successful pairing.

3. Install Transmitter
The ERA-PBTX transmitter can be installed using either the provided double-sided tape or screws:
- Using Double-Sided Tape: Clean the desired mounting surface thoroughly. Peel off the backing from the double-sided tape and firmly press the transmitter onto the surface.
- Using Screws: Separate the front cover from the back plate of the transmitter. Use the back plate as a template to mark the screw holes on your desired surface. Drill pilot holes if necessary, then secure the back plate with the provided screws. Snap the front cover back onto the secured back plate.

Operating Instructions
Alert Modes
The ERA-RXPG receiver offers multiple alert modes to suit your needs:
- Melody Only: The receiver will play a selected melody when activated.
- Strobe Only: The receiver's LED light will flash brightly when activated. This mode is ideal for individuals with hearing impairments or in noisy environments.
- Melody + Strobe: The receiver will play a melody and flash its LED light simultaneously.
Use the mode switch on the side of the receiver to cycle through these options.
Volume Adjustment
The receiver features adjustable volume levels up to 90dB. Use the volume button on the side of the receiver to increase or decrease the sound output to your preferred level.
Wireless Range
The system boasts an impressive wireless range of up to 4000 feet (approximately 3/4 mile) in open air. This allows for flexible placement of the receiver throughout your home or business, even through multiple walls and floors.
Maintenance
Battery Replacement
The ERA-PBTX transmitter uses one CR2450 lithium battery, which typically lasts up to 3 years under normal usage. When the battery is low, the receiver may repeatedly play the melody sound even after a single press. Replace the battery by following the steps in the 'Install Transmitter Battery' section.
Cleaning
To clean the doorbell system, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the unit. Ensure the units are unplugged before cleaning.
Troubleshooting
- No response from receiver when transmitter is pressed:
- Check if the receiver is plugged into a working electrical outlet.
- Verify the transmitter battery is installed correctly and is not depleted. Test the battery by pressing the center button; a green light should appear for two seconds.
- Ensure the transmitter and receiver are within the operational range (up to 4000 feet in open air). Obstacles like thick walls or metal structures can reduce range.
- Re-attempt the pairing process as described in the 'Setup' section.
- Receiver repeatedly plays melody:
- This indicates a low battery in the transmitter. Replace the CR2450 lithium battery.
- Strobe light not flashing:
- Check the mode switch on the receiver to ensure it is set to 'Strobe Only' or 'Melody + Strobe' mode.
