Instructions
Baby sound B pocket Fetal doppler A handheld equipment for detecting fetal heart rate (FHR) Designed specifically for the daily detection of fhr for the family of pregnant women. Pregnant women can work on their own to hear fetal heart sound and calculate fhr to preview and realize the purpose of care for the fetus. Baby voice B is a high performance model with LCD digital display.

Main features
Integrated probe and headunits
■ Precise and compact design, portable to use
Especially 2 headphone sockets design can allow parents to hear fetal heart sound together
■ High sensitive doppler probe
■ Low ultrasound output density, much lower and relatively safe quality than relative government standard
■ Low power consumption, two AAA size batteries can last more than 8 hours for continuous use (depends on battery type and volume)
■ To record fetal heart sound with recording cable Can be connected to a computer or recorder
LCD FHR display with high accuracy
■ The display will be automatically locked without signal for 15 s, which is suitable for the operation of pregnant women separately
