• Try recharging or replacing the battery pack.
• If the Baby Unit is too far away it may be going out of range, so move the Baby Unit closer to the Parent Unit.
• Reset the units by disconnecting them from the battery and electrical power. Wait about 15 seconds before reconnecting.
• Allow up to one minute for the Baby Unit and the Parent Unit to synchronise.
See 2.4 Registration (Pairing), if there is a need to re-register the units.
