Why aren't the units linking?
• Make sure the units are within range of one another.
• Check if both units are turned on.
What do I do if the battery is showing as low on the Parent unit?
• Plug the unit into a wall power socket to charge it. It's best to leave the unit
plugged in whenever you can, to make sure the batteries are always charged.
• To fully charge the batteries, the Parent unit should be on charge for about 16
hours if switched off and 24 hours if switched on.
• To speed things up, turn the Parent unit off when charging if it's not being used.
Why is my Parent unit very quiet?
• You may have set the volume too low. See 11.
• You may have switched Mute on. Take a look at 11.
Why is there a high-pitched noise coming out of one of the units?
• The units might be too close to each other.
• The volume setting might be too high.
