Frequently asked questions

Below are the questions most frequently asked about the baby monitor. If you cannot find the answer to your question, visit our website at www.vtechphones.com, or contact 1 800-595-9511 for customer service.

Why doesn’t the POWER light on the baby unit turn on when I switch on the units?| Perhaps the baby unit is not connected to the power supply. Connect the baby unit to power
supply. The baby unit turns on.
---|---
Why doesn’t the POWER / LINK light on the parent unit turn on when I switch on the units?| Perhaps the battery of the parent unit is empty and the parent unit is not connected to power supply.
Connect the parent unit to power supply; or insert two new AAA alkaline batteries into the parent unit. The parent unit turns on and establishes connection with the baby unit.
Why does the baby monitor not respond normally?| Try the following (in the order listed) for common cure:

1. Make sure that both baby unit and parent unit are on.
Disconnect the power from the baby unit and the parent unit.
2. Remove the batteries from the parent unit.
3. Connect the baby unit to the power supply again. The baby unit turns on.
4. Connect the parent unit to the power supply again; or insert two new AAA alkaline batteries. The parent unit turns on.
5. Wait for the parent unit to synchronize with the baby unit. Allow up to one minute for this to take place.
6. Press or to adjust the speaker volume on the parent unit.

Why does the baby monitor produce a high-pitched noise?| The units may be too close to each other. Make sure the parent unit and the baby unit at least 1 meter / 3 feet away from each other.
Why don’t I hear a sound/ Why can’t I hear my baby cry?| Make sure that both baby unit and parent unit are on. If you see the visual sound indicators light up, but there is no sound, then you may have muted the volume or set it to a lower level. Adjust the volume to a higher level.
---|---
If the visual sound indicators do not light up, and you cannot hear any sound, it is because the baby sound is too low for the baby unit to detect. This is normal. Place the baby unit at least 3 feet / 1 meter away from your baby.
Why does the parent unit beep?| The parent unit beeps three times every 30 seconds when the baby unit is out of range. Move the parent unit closer to the baby unit (but not less than 3 feet / 1 meter).
If the parent unit is powered by batteries, the parent unit beeps twice every 10 minutes and the LOW BATTERY light flashes in red when the battery is low. Replace with two new AAA alkaline batteries.
Why does the parent unit LOW BATTERY light flash?| If the parent unit is powered by batteries, the parent unit beeps twice every 10 minutes and the LOW BATTERY light flashes in red when the battery is low. Replace with two new AAA alkaline batteries, or remove the batteries, and connect the parent unit to the power supply.
Why can’t I establish a connection? Why is the connection lost every now and then?
Why are there sound interruptions?| The baby unit may be out of range. Move the parent unit closer to the baby unit (but not less than 3 feet/ 1 meter).
Other electronic products may cause interference with your baby monitor. Try installing your baby monitor as far away from these electronic devices as possible.
How come the battery backup power depleted so quickly?| Alkaline batteries are recommended. If you use other kind of batteries, the performance of the baby monitor varies.
This is an AC powered baby monitor. The two AAA alkaline batteries are for backup power use, and there is no battery recharging from the parent unit.
Do not mix old and new batteries. Do not mix alkaline, standard (Carbon-Zinc) or rechargeable (Ni- Cad, Ni-Mh, etc) batteries.
