2. Mailbox Sensor Placement and Dial Setting
The sensor's effectiveness depends on its correct placement and dial setting, which varies by mailbox type. The arrow on the sensor should point in the direction the mailbox door opens.
Image: Diagram showing how to set the internal dial (TYPE1/TYPE2) and mount the sensor for curbside, wall-mounted, and slot-type mailboxes. The arrow on the sensor must point towards the opening direction.
- Curbside Mailbox (TYPE1): Set the internal dial to the Left (TYPE1). Mount the sensor with arrows pointing towards the top of the mailbox door.
- Wall-Mounted Mailbox (TYPE2): Set the internal dial to the Right (TYPE2). For mailboxes with large tapered lids, mount with arrows on the sensor pointing up. For mailboxes with short tapered lids and flat tops, mount with arrows on the sensor pointing up.
- Slot Type Mailbox (TYPE1): Set the internal dial to the Left (TYPE1). Mount with arrows on the sensor pointing towards the hinge.
Clean the inside surface of the mailbox door where the sensor will be placed. Use the provided 3M adhesive tape to securely fix the sensor. Ensure the sensor is firmly pressed against the surface for a good bond.

3. Receiver Installation
The receiver unit should be placed indoors, ideally within the specified wireless range of the mailbox sensor. It can be installed using either 3M adhesive tape or screws.

Plug the receiver into a standard 110V-240V AC power outlet.
Operating Instructions
1. Power On and Initial Pairing
Once the receiver is plugged in and the sensor has batteries, the system is ready. The units are typically pre-paired from the factory. If they do not connect automatically, refer to the troubleshooting section for re-pairing instructions.
2. Receiving Alerts
When the mailbox door is opened, the sensor will transmit a signal to the receiver. The receiver will then:
- Emit a buzzing sound 10 times.
- Flash its red LED indicator.

3. Adjusting Volume
The receiver unit has buttons to adjust the volume of the alert sound.

4. Resetting the Alarm
After an alert, press the 'R' (Reset) button on the receiver to silence the alarm and clear the flashing LED.

Maintenance
1. Battery Replacement
The mailbox sensor is powered by 2 AAA batteries. Replace them when the sensor's performance degrades or if the receiver fails to register alerts despite the mailbox being opened. Follow the battery installation steps outlined in the Setup section.
2. Cleaning
Wipe the sensor and receiver units with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
3. Environmental Considerations
The sensor is designed to withstand various weather conditions, including temperatures from -40°F to 158°F. However, ensure it is securely mounted to prevent dislodgement during extreme weather.

Troubleshooting
- No Alert When Mailbox Opens:
- Check sensor batteries and replace if necessary.
- Ensure the sensor is correctly positioned and the internal dial setting matches your mailbox type (refer to "Mailbox Sensor Placement").
- Verify the receiver is plugged in and powered on.
- Check the distance between the sensor and receiver. Obstacles like thick walls or metal structures can reduce range. Try relocating the receiver closer or to a window facing the mailbox.
- If the receiver was recently unplugged, allow a few minutes for it to reset and reconnect.
- False Alarms:
- Ensure the sensor is securely mounted and not shifting.
- Re-check the sensor's dial setting and orientation for your specific mailbox type.
- Weak Signal/Intermittent Alerts:
- Replace sensor batteries.
- Reduce the distance between the sensor and receiver.
- Avoid placing the receiver near large metal objects or other electronic devices that might cause interference.
