915-BL Dual-Frequency Doppler
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 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.

    Why is it hard to hear blood sounds on my Parks 915-BL Medical Equipment?
    • T
      Tyler HoffmanNov 2, 2025
      If you're struggling to hear blood sounds clearly with your Parks Medical Equipment due to a poor signal-to-noise ratio, it might be because of too much noise or a weak signal. To address excessive noise, prevent feedback by ensuring the probe remains firmly against the skin with gel applied, is positioned away from the speaker's sound waves, and its cable isn't looped. Check for circuit issues by listening for smooth white noise with the probe disconnected and volume up; crackling indicates a problem requiring technical support. Also, tap the panel to check for a ringing noise, which may indicate a microphonic circuit needing attention. Inspect the probe for noise by cleaning and drying its crystal end, wiggling the plugs to check for crackling, and cleaning/tightening them if necessary. ...
