Troubleshooting Guide for Pairing Vitalograph BT12 ECG BT Device
INITIAL CHECKS
Disconnect any USB 3.0 external USB hard drives from the PC/Laptop as they can interfere with any Bluetooth
signal and, in this case, the Bluetooth signal between the BT12 device and the computer. Other USB 3.0 Bluetooth
devices such as flash drives also have potential to cause interference and should be disconnected. This is not
unique to our device and further information can be found here;
www.bluetoothandusb3.com/the-explanation
1.
Some Laptops or PC’s may have an internal built-in Bluetooth adapter. It should be possible to pair the BT12 ECG
device to the computer without the need for the supplied external Startech USB BT adaptor dongle. Reference
NOTE 1 on how to turn this On/Off.
2.
Section 2. Contraindications, warnings, precautions and adverse reactions above indicates that “The user is
responsible for ensuring that data transmission is not corrupted by too many wireless senders or receivers in the
vicinity.” Please also review BT12 ECG Regulatory Notice 07651. Possible sources of interference are other
devices which share the 2.4Ghz frequency band such as mobile phones, cordless phones, microwave ovens,
fluorescent lighting, wireless cameras or security systems, baby monitors, wireless speakers, remote-control toys,
wireless pointing devices, wireless networking devices, Wi-Fi base station, wireless video.
3.
BT12 Regulatory Notice 07651 and Section 2. Contraindications, warnings, precautions and adverse reactions
above also indicate that “If interference is suspected or possible, switching off the offending device is the normal
solution, as is required in aircraft and medical facilities”
4.
Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. Metal,
bulletproof glass, concrete, plaster, marble and brick are examples of signal blocking materials. So, if you’re really
struggling with interference, your first step should be to move your Bluetooth devices away from these materials.
That means no physical barriers between you and your devices, and definitely no metal desks! (Ensure that BT12
ECG device is within line of sight to Startech BT adaptor dongle on PC/Compact if possible)
5.
BT12 ECG DEVICE/CONNECTION CHECKS
Verify BT12 ECG device battery charge status. Replace the batteries when the BT12 ECG device display “battery
symbol” flashes or shows no more bars.
1.
Ensure that BT adaptor dongle being used is Startech USBBT1EDR2. This should be clearly marked on the device
