using it again.
Make sure that the Bluetooth monitor to which the measured data is transmitted is invisible to other Bluetooth
end devices. Otherwise, there could be errors in the data transmission.
BT12 operate safely and effectively in an environment where BT devices and WLAN devices coexist. But some
restrictions have to be considered. We recommend using the BT12 device together with a maximum of two other
BT ECG devices within the range of each BT ECG device. Furthermore, any WLAN sender or receiver (e.g.
WLAN USB dongles for PCs) should be placed more than 1 meter away from the BT12 and the BT receiver (BT
USB dongle for PCs) respectively. Otherwise, BT12 will lose data packets. The user is responsible for ensuring
that data transmission is not corrupted by too many wireless senders or receivers in the vicinity.
Refer to the appendix at the end of this User Training Manual for a troubleshooting guide on pairing the
Vitalograph ECG.
