3. If the Merlin 2 PCS locks up again, reboot again. If the problem continues, contact your
Abbott Medical representative.
RF Communication Problems
RF Communication problems may be present if you interrogate an RF-enabled implantable device
and:
The Merlin™ 2 PCS does not display the Ready To Connect to Device or Active RF

Telemetry icons (page 13).
Few or no telemetry strength indicators are lit on the Merlin™ Antenna.

The Merlin 2 PCS displays a communication alert.

Make sure that the cable from the Merlin™ Antenna to the Merlin 2 PCS is properly connected,
and the blue status LEDs on the Merlin Antenna are on. Follow the steps in RF Communication
Setup (page 10). If the problem persists, consider the options in the section Suboptimal RF
Communication (page 19) below.
Suboptimal RF Communication
The Merlin™ 2 PCS indicates the quality of the RF communication by the telemetry strength
indicators on both the programmer and the Merlin™ Antenna. Below is a list of possible causes of
suboptimal radio communication:
Possible Causes
 The Merlin™ Antenna orientation or location is suboptimal.
People or objects are interfering with the communication between the Merlin Antenna and

the device.
The Merlin Antenna is too far away from the device.

Someone is holding the Merlin Antenna.

Other products nearby are causing electromagnetic interference (EMI).

The Merlin Antenna cable is wound around the Merlin Antenna.

Solutions
Try to optimize RF communication (increase the number of telemetry strength indicator LEDs):
Move or reorient the Merlin™ Antenna slightly.

Make sure that the space between the Merlin Antenna and the device is free from interfering

objects or people.
Move the Merlin Antenna closer to the device.

Make sure that the front of the Merlin Antenna faces the implantable device.

Power off or remove equipment nearby that could cause EMI.

Make sure the Merlin Antenna cable is not wound around the Merlin Antenna.

Do not hold the Merlin Antenna.

If none of the above solutions solve the problem, avoid using RF communication and use the
inductive telemetry wand instead.
BLE Communication Problems
BLE Communication problems may be present if you interrogate a BLE-enabled implantable
device and:
The Merlin™ 2 PCS does not display the Ready To Connect to Device or Active BLE
