7. Monitor Patient Heart Rate

The Model 3100 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. 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 3100 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 3100 comes with a AA Alkaline battery. This battery will last for approximately 60 hours of continuous use. In a

typical clinical setting, this represents about three months.

As the alkaline 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 3100. However, battery type must be

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