B. RX
Mode
Without a Chest Piece Assembly plugged into the Chest Piece jack of the TR-1, the unit
is automatically in the Receive Mode. With the Data Communications Channel
established and a Headset plugged into the Headset jack of the unit, the clinician is set
up to hear the stethoscope sounds from the remote AMD-3700 (in Transmit Mode).
Volume to the Headset can be increased by turning the Volume control clockwise.
Increasing the volume too high can cause distortion in the Headset and will also
increase the background noise. Start with the lowest volume necessary to hear the
sounds, then turn up the volume as needed to focus in on specific sounds.
The B/D Switch can be used in an auscultation exam similarly to a traditional
stethoscope. The Bell (B) position cuts off the high end at 250 Hz and boosts the low
frequency sounds below 100 Hz for enhanced heart auscultation. The Diaphragm (D)
position slightly reduces the very low frequencies and extends the high frequencies to
1,400 Hz.
