Troubleshooting (continued)
The video and audio monitor produces high-pitched
noise.
• The parent unit may be too close to the baby unit or another parent
unit. Make sure the parent units and the baby unit are at least
1 metre away from one another.
• You may be too close to the baby unit or another parent unit when
you press and hold TALK. Make sure the parent units and the baby
unit are at least 1 metre away from one another.
• You may have set the sensitivity level too high. You may need to
adjust the sensitivity level to a lower level to avoid audio feedback
(page 21).
My parent unit plays any sounds from the baby unit and
I think it is too noisy.
• You may have set the sensitivity level to the highest level
(LEVEL 5). If you do so, the baby unit will transmit any sounds
detected to the parent units. You may need to adjust the sensitivity
level to a lower level (page 21).
• You may need to adjust the speaker volume on the parent unit
(page 19).
My parent unit does not play any sound when there is
noise from the baby unit.
• Make sure the parent unit is powered up by connecting it to AC
power (page 7) or to the rechargeable battery pack provided (page 7) or to the rechargeable battery pack provided
(page 5).
• Make sure the power adapter and the parent unit are plugged in
correctly and securely (page 7).
• Make sure the parent unit is turned on (19) and the speaker volume
is not set to VOLUME OFF (page 19).
• The parent unit may be too far away from the baby unit. Move the
parent unit closer to the baby unit (but not less than 1 metre).
• If the parent unit is powered by the provided battery pack, make
sure there is sufficient charge. Charge the battery in the parent unit
for up to 12 hours.
