Troubleshooting (continued)
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 5) or to the rechargeable battery pack provided (page 3).
•Make sure the power adapter and the parent unit are plugged in correctly and securely (page 5).
•Make sure the parent unit is turned on (page 17) and the speaker volume is not set to
VOLUME OFF (page 17).
•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 pack, make sure there is sufficient charge. Charge the battery in the parent unit for up to 11 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 12).
•Other electronic products such as HAM radios and DECT cordless phones can cause interference with your audio monitor. Try installing your audio monitor as far away as possible from these types of electronic devices.
•Large obstructions may impact the reception. Try to relocate the baby unit, away from large obstructions such as walls and doors.
•Completely remove and install the battery 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.
