The manually-timed rate is shown for about 12 seconds, without a heart symbol
and with the ultrasound switched off. The SonicaidOne then switches itself off.
To restart the SonicaidOne during the manual count period, release the manual
count button, then hold it down again.
If 'E' is shown on the display, this indicates operator error. Release the manual
count button, and try again.

Using a headset (optional)

For private listening, or in a noisy environment, use a headset with the
SonicaidOne. Insert the headset jack securely into the headset socket. When
the headset is connected, the speaker is muted.

Using the SonicaidOne for water births

The SonicaidOne probe will withstand submersion up to a depth of one metre.
Submersion should be limited to the time necessary to carry out an
examination.
Ask the mother to raise herself if necessary so that her abdomen is out of the
water for the short time it takes to obtain a satisfactory rate.
After use, dry the probe thoroughly with a soft cloth. If it is soiled, follow the
cleaning and disinfection procedure detailed in the preventive maintenance
section.

Battery fitting or replacement

Use only two size AA (LR6) alkaline batteries or two fully charged 1.2V nickel-
cadmium rechargeable size AA batteries. New alkaline batteries will give more
than 1000 one-minute examinations. Rechargeable nickel-cadmium batteries
will give approximately 250 one-minute examinations.
When the battery low indicator is displayed, change the batteries at the earliest
opportunity.
