Troubleshooting (continued)
The parent unit plays any sounds from the baby unit and I think it is
too noisy.
You may have set the sensitivity level to Level 5 (Maximum). If you do so, the baby
unit will transmit any sounds detected to the parent unit. You may need to adjust the
sensitivity level to a lower level (page 23).
You may need to adjust the speaker volume on the parent unit (page 30).
The 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 12) or to
the rechargeable battery provided (page 10).
Make sure the parent unit is turned on (page 30) and the
speaker volume is not set to
off (page 30) .
Make sure the parent unit is not monitoring in multi-CAM mode.
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 3 feet).
If the parent unit is powered by the provided battery, make sure there is sufficient
charge. Charge the battery in the parent unit for up to 12 hours.
You may have set the sensitivity level to a very low level. If you do so, the baby unit will
not detect sounds that is too soft or light. You may need to adjust the sensitivity level to
a higher level (page 23).
Large obstructions may impact the reception. Try to relocate the baby unit, away from
large obstructions such as walls and doors.
Remove the battery and then install it again. Turn on the baby unit and the parent unit.
Allow up to one minute for the parent unit and the baby unit to synchronize..
Other electronic products may cause interference with your video and audio monitor.
Try installing your video and audio monitor as far away from these electronic devices
as possible: wireless routers, radios, cellular telephones, intercoms, room monitors,
televisions, personal computers, kitchen appliances and cordless telephones.
Battery low at the Parent Unit and display on the parent unit.
Charge t he battery in the parent unit for up to 12 hours.
Remove the battery and then install it again. Use it until fully depleted, then recharge it
in the parent unit for up to 12 hours.
If the above measures do not correct the problem, replace the battery.
