Model EX1100 Quick Start Guide
Place the wand, green side toward you, over the implant. Press the Start button once; the unit beeps and the green light turns on. The transmitter then attempts to connect automatically. If connection fails, wait 30 s and retry. Successful link triggers a steady green light. LED status confirms.
Positioning the Wand
To begin, locate the implant site on the body. Position the wand with its green side facing you, directly over the implant. Hold it steady within a 2‑inch radius. Avoid metal surfaces or nearby electronics that could interfere. Clean and dry the skin to maximize signal integrity. If the wand has a prosthetic or scar tissue, gently adjust until the green LED lights and the unit beeps, confirming a connection. Keep the wand in place for at least 30 seconds after the initial beep to allow the transmitter to establish a stable link. If the green light does not turn on, reposition a few centimeters left or right and retry. Consistent positioning ensures reliable data transmission during daily use and overnight monitoring. The wand’s ergonomic design allows comfortable wear on the wrist or ankle, but optimal placement is always directly over the implant site. Follow these steps each activation to maintain accurate data flow to the receiver. This procedure preserves the integrity of the wireless link between the external unit and the implant. If discomfort or looseness occurs, adjust the strap or use a small adhesive patch. The transmitter’s battery supports up to 24 hours of operation, so regular checks for proper positioning prevent data loss and ensure consistent monitoring. Store the wand in its protective case when not in use to avoid accidental damage and preserve antenna integrity. Repeat the positioning steps daily for optimal performance. Remember to check the green LED after each use; a steady light confirms ongoing connectivity! Thanks.
Starting the Transmitter
After positioning the wand over the implant, press the Start button firmly, then release. The unit will emit a beep followed by a green LED illumination, confirming a successful link. The green side of the wand should face you to align the antenna properly. If the LED stays off, double‑check wand placement and skin cleanliness. A beep confirms the handshake.
When the green LED stays steady, the transmitter automatically sends data to the implanted receiver. The LED pulses slowly to indicate ongoing transmission. The LED remains steady for 5 seconds after connection before pulsing. To pause, press Start again; the LED turns off and the unit enters standby. Press Start once more to resume. Pressing Start again pauses data flow.
The transmitter sends data packets every 30 seconds during active mode. This ensures real‑time monitoring of implant parameters. Data packets are sent every 30 seconds. The battery supports up to 24 hours of continuous use. Keep the wand within 2 inches of the implant. If the LED blinks or signal is lost, consult troubleshooting or contact support.
A battery level indicator flashes when the charge is low. If it flashes rapidly, replace the battery promptly. If the battery indicator flashes rapidly, the unit may be in low‑power mode. Replace the battery promptly to maintain operation. Store the wand in its protective case when not in use.
Following these steps each time you activate the device ensures reliable communication between the external unit and your implant, guaranteeing accurate data capture. Consistent activation ensures continuous monitoring. This guarantees that your health data is accurately captured and transmitted to your healthcare provider.
Avoid placing the wand near metal objects or strong electromagnetic sources. If disconnections occur, reposition the wand or clean the implant area. Firmware updates via the companion app keep the transmitter secure. The device operates between 0°C and 40°C, ensuring reliable performance in typical indoor environments!
Confirmation of Successful Connection
Once the wand is correctly positioned and the Start button is pressed, the transmitter will emit a short beep followed by a steady green LED. This green light indicates that the device has successfully established a link with the implanted receiver. The transmitter will then begin to transmit data automatically, and you will hear a series of short beeps every 30 seconds as packets are sent. If the green LED remains steady for 5 seconds after the initial beep, the connection is stable. In case the LED begins to flash, the unit is in standby mode and will resume transmission when the Start button is pressed again. A continuous green light with occasional rapid beeps confirms that data is being transmitted in real time. If the green LED does not appear or the transmitter does not beep, double‑check the wand placement, ensure the skin is clean, and verify that the battery is charged. A low battery will cause the LED to flash slowly and the transmitter to stop sending data. If the device still fails to connect, consult the troubleshooting guide or contact technical support at 1‑877‑MY‑MERLIN (1‑877‑696‑3754).
The transmitter shows a battery icon that turns amber when the charge drops below 20%. A amber flash signals a low level. Once connected, the unit syncs with the implant’s clock, ensuring timestamps in real time. In the companion app, a checkmark indicatesIf the app shows an error, reset the unit
Resetting the Transmitter

Sending Your Information
The Merlin Home Transmitter automatically sends data during sleep To send manually, press the Start button while the wand is over the implant A green light confirms transmission If the unit beeps and lights remain off repeat the press or check the wand position!
Automatic Data Transmission
The Merlin Home Transmitter is designed to transmit patient data automatically during the night without any user intervention. Once the wand is positioned with the green side facing the implant and the Start button is pressed once, the unit will enter a low‑power listening mode. At the start of the sleep cycle, the transmitter initiates a silent handshake with the implant, confirms a successful link, and begins sending telemetry packets every 30 seconds. The process is fully autonomous; the device will continue to transmit until the battery is depleted or a reset is performed. If the transmitter beeps or the green light remains off, it indicates a communication failure. In that case, remove the wand, re‑position it, and press Start again. The transmitter will then retry the handshake and, upon success, resume automatic data transfer. This feature ensures continuous monitoring of implant parameters such as pacing rate, lead impedance, and battery status, providing clinicians with up-to-date information without the need for manual uploads. The automatic mode is ideal for patients who prefer a hands‑free experience, as it eliminates the need to remember to press the button each night. The device also logs transmission events, allowing the clinic to verify that data was sent successfully during routine follow‑ups. The automatic transmission function complies with regulatory standards, communication, is optimized for low power to extend batterys life. All data is stored safely
Manual Data Transmission
When automatic transmission is unavailable or a clinician requests a real‑time data snapshot, the Merlin Home Transmitter can be used in manual mode. Position the wand with the green side facing the implant, then press and hold the Start button until the transmitter beeps and the green light flashes. Release the button to initiate a one‑time data burst. The device will transmit the current implant status—pacing rate, lead impedance, battery voltage—over the wireless link to the clinic’s monitoring system. If the transmitter fails to beep or the green light does not flash, remove the wand, reposition it, and repeat the Start procedure. Manual transmission is especially useful for urgent checks, verifying a recent implant update, or troubleshooting a suspected communication issue. After the data is sent, the transmitter returns to standby mode until the next scheduled nightly batch or until the user initiates another manual transmission. This feature ensures that patients and clinicians can obtain immediate telemetry without waiting for the nightly batch, providing flexibility in care management and enhancing patient safety. The transmitter’s firmware supports packet sizes up to 256 bytes, allowing complex telemetry to be sent in a single burst. Battery life is rated for up to 30 days of continuous operation in manual mode, after which the unit automatically enters low‑power standby. During each manual transmission, the wand must be kept within 2 inches of the implant; if the green light flickers, gently adjust the wand’s position to restore a strong link. If the green light does not flash, reposition the wand or check the battery; the transmitter will indicate a low‑power status with a single long beep. This ensures daily monitoring for
Troubleshooting Common Issues
If the transmitter beeps but no data appears, check wand placement. Ensure green side faces implant and hold Start until green light flashes. For persistent errors, reset by holding Reset while pressing Start. Contact support at 1‑877‑696‑3754 if lights remain off. If problems continue, reboot unit.
Beacon Beeps and Light Indicators
The Merlin Home Transmitter uses a series of beeps and LED signals to guide users during setup and operation. When the wand is correctly positioned with the green side facing the implant, a single short beep confirms initial contact. The transmitter then emits a steady green light, indicating that the device is ready to transmit data. If the green light does not appear, double‑check the wand orientation and ensure the transmitter is powered on.
During normal operation, the transmitter beeps once every 30 seconds to signal that data is being sent successfully. A rapid sequence of three beeps followed by a pause indicates a communication error; in this case, the transmitter will flash red. Users should then reposition the wand or power cycle the unit. A continuous red light with no beeps means the transmitter has lost power or the battery is depleted—replace the battery or connect to a charger.
When the transmitter is in reset mode, a long beep is followed by a blinking amber light. Hold the Reset button until the amber light stops blinking, then press Start again to complete the reset. If the amber light remains steady after resetting, contact technical support. The support hotline is 1‑877‑696‑3754, available Monday to Friday, 8 AM to 8 PM EST.
Users should also be aware of the “sleep mode” indicator: a single brief beep and a dimmed green light mean the transmitter is in low‑power mode, automatically waking to transmit data during sleep cycles. If the transmitter does not wake, ensure the device is within 10 cm of the implant and that no obstructions interfere with signal transmission.
If the transmitter emits a single long beep followed by a blinking green light, this indicates a firmware update is in progress. The user should not interfere until the green light stabilizes. During firmware updates, the transmitter will not transmit data; once the green light steadies, normal operation resumes.
In rare cases, the transmitter may emit a continuous beep with no light changes, signaling a critical fault. Users should immediately disconnect power and contact support.
The LED indicator colors: Green – normal operation, Amber – warning or reset mode, Red – error or low battery, Off – powered off. The beep patterns: Short beep – successful connection, Double beep – error, Long beep – reset or firmware, Continuous beep – fault.
