Tips for Use

• We recommend use only during the last
trimester (28-40 weeks) of pregnancy.
This is when fetal sounds are strongest.
• Do not expect this product to amplify
sounds the same way a Doppler device
amplifies sounds.
• Make sure battery power is not too low.
Use only a new, 9 volt alkaline battery
in the monitor.
• Use the monitor only in a quiet room.
• The best time to listen is 3-4 hours
after eating, when you are relaxed
and have a slower heartbeat.
IMPORTANT! Avoid laying flat on
your back for an extended period
of time while using this product.
• Use the monitor on bare skin.
Additional barriers between baby
and the amplifier will affect your
chance of hearing fetal sounds.
• Position the volume control at
a moderate level to avoid static.
