Getting started
Positioning and operating range
Positioning the audio monitor
Place the parent unit within the operating range (see below) of the baby unit.
We recommend you place the parent unit at least 3 feet away from the baby
unit to avoid audio feedback. If you still experience audio feedback, move the
parent unit and the baby unit farther apart.
Audio settings
The baby unit may not detect sounds when the sensitivity level is set below a
certain level. You may need to increase the sensitivity level (see page 12).
You may need to turn the speaker volume on the parent unit louder to hear
the sounds transmitted from the baby unit (see page 17).
Operating range
The operating range of the audio monitor is up to 1,000 feet outdoors or
150 feet indoors. The actual operating range may vary depending on the
environmental conditions and other interferences such as walls, doors and
other obstructions.
It is the caregiver’s responsibility to stay close enough to take care of
any eventuality.
At least 3 feet
