Special instructions:
STORAGE CONDITIONS:
Recommended shipping and storage at 5°C - 40°C, non-condensing
Avoid direct sunlight
Maintenance and Cleaning: The Monitor has a useful life of 5 years. The Monitor contains no user
serviceable components and requires no maintenance or calibration. Keep it clean and free of dust.
The exterior may be cleaned using the following steps:
1. After every use, check the Monitor for any sign of damage or wear. Remove any external lead still
connected in the A or B ports and discard per local procedures.
2. Wipe the Monitor with a dry or water-moistened soft cloth, Isopropyl Alcohol, Ammonium
Hydroxide based surface cleanser, Ammonium Chloride based surface cleanser or 2% bleach solution.
Ensure any residual organic material is removed. Do not pour or spray liquid directly on the Monitor.
Allow to air dry before use.
3. Do not put liquid near the speaker.
4. The FLOW COUPLER Monitor is no longer usable when hardware buttons, LCD screens are
inoperable, or audible signal is not generated when connected to the FLOW COUPLER probe.
The Following Sections apply to the FLOW COUPLER 20 MHz Doppler Probe
Acoustic Output: There are no user controls meant to a ect acoustic outputs. All acoustic outputs are
below the application speci c pre-amendments acoustical output limit of an Ispta of 94 mW/cm
a MI of 1.9.
Explanation of Derivation of Derating Factor: The derated intensity calculations are based on
measured center frequency of the acoustical signal (f, MHz) and the distance from the transducer
under test to the hydrophone (z, cm) using the derating factor e.
