7. Monitor Patient Heart Rate
The Model 3200 detects and displays an acoustic-based heart rate when presented with consistent heart sounds (heart rate
variation < 10%). It takes five seconds to compute the initial heart rate and updates are provided every two seconds. The
heart rate will then be displayed for 10 seconds after removal of the chestpiece from the patient. Prior to the initial reading,
the display shows two dashes (--). For heart rates outside a range of 30-199 bpm, the display will also show two dashes (--).
The acoustic-based heart rate display functions best when the Model 3200 is placed near the apex of the patient’s heart and
can be monitored while using any filter mode and/or volume level. If the heart rate changes from consistent to inconsistent or
if there is excessive ambient noise, patient movement or lung sounds during auscultation, the heart rate display number will
display two dashes (--).
8. Monitor Battery Life
Battery life is indicated by an icon in the LCD display.
The Model 3200 comes with a AA Alkaline battery. Battery will provide approximately 50-60 hours of continuous use,
depending on the frequency of Bluetooth data transfers. In a typical clinical setting, this represents about three months of
use.
As the battery life depletes, the icon will change as follows:
The battery icon begins to blink when only a few hours of battery capacity remains.
CAUTION: When the battery is completely depleted the scope becomes inoperable. No sound will be transmitted without
a functioning battery.

In order to transfer data between two Bluetooth devices, they must first be “paired” electronically. Pairing is a discovery and
authentication process that allows your Bluetooth equipped Model 3200 to communicate with another Bluetooth equipped
device and establishes the link between these two devices as a trusted pair. The pairing process requires user operations to
be performed on both the Model 3200 and the external device. While the Model 3200 can remember trusted pairing with up
to eight different Bluetooth devices, it will only communicate with one paired device at a time. In addition, you cannot pair a
Model 3200 with a second Model 3200.
How to pair the Model 3200 with an external device:
1. Initiate pairing process: On the Model 3200, depress and release the (M) button. The MAIN menu will be displayed.
Use the (-) button to scroll down to the PAIR option. Select this option by pressing and releasing the (M) button. The LCD
screen will signal that pairing is in progress with the following animated display:
During the pairing process the Model 3200 will make itself discoverable to other Bluetooth equipped devices.
Note: The Personal Identification Number (PIN) for Bluetooth pairing is displayed in the lower left-hand corner of the LCD
screen
2. Select Model 3200 on external Bluetooth device: Follow the pairing instructions found with your Bluetooth equipped
device. In general, you will need to make sure that the Bluetooth mode is enabled on the device, and once the Model
3200 has indicated the external device has been found, you may need to confirm the connection on the external
device. Please remember that the distance between the Model 3200 and the Bluetooth device is limited to no more
than 10 meters. If pairing is successful, the LCD display of the Model 3200 will show a flashing Bluetooth icon and
the stethoscope will be ready for wireless operations. Once the Model 3200 is connected to the external device, the
Bluetooth icon will stop flashing and be displayed continuously.
If the Bluetooth connection with the external device is subsequently lost or times out, the Bluetooth icon will disappear from
the LCD display.

12. Other Operating Considerations
Operating range is -22º to 104ºF (-30º to 40ºC), 15 to 93% relative humidity.
Storage and transport range is -40º to 131ºF (-40º to 55ºC), 15 to 93% relative humidity.
To extend the life of your stethoscope, avoid extreme heat, cold, solvents and oils. Remove the battery whenever the
stethoscope will not be used for several months.
If you plan to use the stethoscope below 0ºF (-18ºC) you should use a lithium battery to insure proper function.
