Always use the SensiCardiac software to pair your Littmann.
For best performance, use the Bluetooth dongle provided with your Littmann 3200. Your PC or laptop's Bluetooth dongle may not be compatible with the Littmann 3200.
After completing the pairing process and the status (Littmann serial number) is not displayed, restart the SensiCardiac software.
Although the Bluetooth connection may work over several feet, for best performance stay within 3 feet from your PC/Laptop.
