MySentry Monitor
46 Frequently asked questions
How do I resolve RF interference issues?
When you experience an RF communication issue, the MySentry Monitor identifies which device is
having the problem by issuing an alarm. Communication problems can usually be resolved by:
• ensuring that there is less than six feet (1.8 meters) between the pump and Monitor, or the pump and
Outpost;
• turning off or moving away from other RF transmitting devices;
• reorienting or relocating the transmitter or receiving device, or both.
Communication problems may also occur due to cellular telephone interference. Testing conducted
with several different cellular telephones indicates that, while a glucose value is being transmitted,
using a cell phone within 12 inches (31 cm) of receiving devices, transmitters, or RF glucose meters
can interfere with the reception of transmitted values. In the event of such interference, normal
communication can be re-established by:
• turning the cell phone off;
• keeping the cell phone at least 12 inches (31 cm) away from the receiving device, transmitter or glucose
meter when a glucose measurement is being transmitted.
What is the recommended distance to keep the pump/transmitter away from other RF devices?
There is no need to separate the pump from other RF devices unless you are receiving interference. If
you are receiving interference, reposition the devices until the interference stops.
How often do I need to re-link the pump to MySentry?
Unless you are experiencing RF interference that you cannot resolve, or there has been a system
failure that has cleared the settings on the pump, you only need to link the pump to MySentry once.
After initial linking, even if the power supply is unplugged, MySentry will automatically resynchronize
upon power-up.
If you do need to re-link, it may take up to seven minutes.
