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 ﬁ ve 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 ﬁ lter 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.

IMPORTANT! NiMH (rechargeable) and Lithium batteries may also be used in the Model 3200. However, battery type must be

speciﬁ ed to ensure a reliable battery life indication (see Custom Conﬁ guration section below).

5. Select Filter

This electronic stethoscope allows the user to select between three different digital frequency ﬁ lters to better emphasize the

speciﬁ c patient sounds of interest.

• The Bellmode ampliﬁ es sounds from 20 - 1000Hz, but emphasizes lower frequency sounds between 20 - 200Hz.

• The Diaphragm mode ampliﬁ es sounds from 20 - 2000Hz, but emphasizes the sounds between 100 - 500Hz.

• The Extended Range mode ampliﬁ es sounds from 20 - 2000Hz similar to the Diaphragm Mode, but provides more

low frequency response between 50 - 500Hz.

The default setting is the Diaphragm ﬁ lter. Instructions for changing the default ﬁ lter setting are given in the Custom

Conﬁ guration section below.

To select ﬁ lter: Depress and release ﬁ lter button (as shown in diagram) until desired ﬁ lter mode appears on the LCD display.

6. Adjust Sound Ampliﬁ cation Level

The Model 3200 sound level can be ampliﬁ ed in 8 increments up to 24X ampliﬁ cation of a non-electronic (cardiology-level)

stethoscope. Level 1 is equal to a non-electronic stethoscope. Level 9 is equal to 24X ampliﬁ cation of a non-electronic

stethoscope. The greater the ampliﬁ cation, the more bars you will see.

A default start-up ampliﬁ cation level can be set using the instructions provided in the Custom Conﬁ guration section below.

The default setting is marked by the box on the vertical bar shown in the volume icon in the LCD display. The illustration

shows a default ampliﬁ cation setting at Level 3.

• Increase Ampliﬁ cation: Press ( + ) button until desired ampliﬁ cation level is achieved

• Decrease Ampliﬁ cation: Press ( - ) button until desired ampliﬁ cation level is achieved
