Nano MTQN-MNG3-B01 Device Guide
Keep the device on the opposite side of the body from the pacemaker to add extra distance between the
pacemaker and the device.
Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or
jacket pocket directly over the pacemaker).

Communications Flow
MTQN-MNG3-B01
The MTQN-MNG3-B01 provides full UART from the cellular radio to the processor as well as the user application.
Model B01 provides a direct USB interface connection to the radio, but not through the 40-pin connector.
Switching between the USB interface and serial port requires a reset. The cellular radio checks for a USB
connection upon reset. If USB is not present, it only uses the serial port. If USB is present upon reset, it only uses
USB.
