Operating/Service Manual
Read this manual prior to use.
Follow manufacturer’s guidelines for safety and maintenance of equipment.
This instrument was manufactured to comply with all relevant national or international regulations and
left the factory in safe condition. In order to keep this instrument in a perfect and safe condition, it is up
to the user to observe all instructions and warnings included in this manual.
The 915-BL Dual-Frequency Doppler is two Dopplers in one case. The low-frequency nominal 2 MHz
precordial probe may be used to detect the passage of air emboli in the heart. The high-frequency nominal
8-9 MHz pencil probe is used for systolic pressures at sites where a stethoscope is not used, as well as
to detect blood pressures that are too low for a stethoscope to auscultate. This probe can also be used to
listen for blood fl ow and pulses distal to arterial repair.
A built-in cautery suppressor with a controllable threshold shuts off the sound when the interference gets
too high.
