3.0 Using the SimulScope for Teaching.
3.1 Using the Heartman Infrared headphone
Locate the Heartman infrared headphones, Cat. No. 718-7040 (Figure 12).
The headphone has an individual volume control that should
be in the
OFF
position when not in use. The battery has a long life
and does not require charging.
The headphone will turn itself off
automatically when placed in a horizontal position.
The battery
shelf life is approximately three years.
The battery will operate for over 150 hours. Additional batteries can
be obtained locally or from Cardionics. A standard 9V. alkaline battery
is recommended as a replacement.

3.2 For bedside teaching
The SimulScope is designed for bedside teaching, but can also be used in the classroom with the
CardioSim Digital Heart Sound System, or with SAM, the Student Auscultation Manikin.
At the bedside, attach the stethoscope to the
Stethoscope INPUT
on the rear panel, then turn the
volume control
ON
. We recommend that the volume control be moved to full volume position and
the sound volume level adjusted in the headphones. When the volume control is
ON
, a green light
should glow brightly and three LEDs on the front panel (red, green and yellow) will also be lit. If
any of these LEDs are not lit, the SimulScope should be returned for repair. It can still be used on
an interim basis, but when convenient return to Cardionics for repair.
Adjust the graphic equalizers controls as shown in Figure 13 for normal sounds. The
X
indicates normal
heart sounds and the
O
indicated normal breath sounds. A label for the graphic equalizer adjustments is
located on the top panel of the SimulScope. Moving the filter controls upward will accentuate a frequency
and moving them downward will attenuate a sound frequency.
