Suboptimal radio frequency (RF) communication.
The Merlin PCS indicates the quality of the RF
communication by the telemetry strength indicator LEDs on both the Merlin PCS and the Merlin
Antenna. Below is a list of potential causes to suboptimal radio communication:
Table 4. Possible causes and solutions for suboptimal RF communication
Possible Causes
Solutions
The Merlin Antenna orientation/location is
suboptimal.
Move or reorient the Merlin Antenna slightly. Make
sure that the front of the Merlin Antenna faces the
implantable device.
People or objects interfere with the communication
between the Merlin Antenna and the device.
Make sure that the space between the Merlin
Antenna and the device is free from interfering
objects/people.
The Merlin Antenna is too far away from the
device.
Move the Merlin Antenna closer to the device.
