Place the parent unit within the operating range 

of the baby unit. We recommend the parent 

unit is at least 1 meter (3 feet) away from the 

baby unit to avoid audio feedback. If you still 

experience audio feedback, move the parent 

unit and the baby unit farther apart. 

The operating range of the baby monitor is 

up to 300 meters (1000 feet) outdoors or 

50 meters (160 feet) indoors. The actual 

operating range may vary depending on 

the environmental conditions, and other 

interferences such as walls, doors, and other 

obstructions. 

 

 

You may test the baby monitor before initial 

use, and at regular times thereafter. 
To test your baby monitor:

Place the parent unit and the baby unit in the 

same room to test the product.
Press and hold   on the baby unit until the 

POWER light turns off.
Press and hold   on the baby unit again 

until the

Below are the questions most frequently asked about 

the baby monitor. If you cannot find the answer to 

your question, contact customer service by visiting our 

website at 

www.vtechphones.com or

Why does the baby 

monitor not respond 

normally?

Try the following (in the order 

listed) for common cure:

1. 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 units. Allow up to 

one minute for this to  

take place.

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 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 does the 

parent unit react 

too quickly to other 

sounds?

The baby unit also picks up 

other sounds than those 

of your baby. Adjust the 

speaker volume on the  

parent unit.

Why don’t I hear a 

sound/Why can’t I 

hear my baby cry?

You may have muted the 

volume or set it to a lower 

level. You may need to  

adjust the volume to a 

higher level.

Why does the  

parent unit beep?

The baby units may be out 

of range. Move the parent 

unit closer to the baby units 

(but not less than 1 meter / 

3 feet).

Why does the  

parent unit 

BATTERY light 

flash?

When the parent unit is 

powered by batteries, there 

is not sufficient power for 

the parent unit to perform  

normally. Replace with two 

new AAA alkaline batteries.

Why can’t I establish 

a connection? Why 

is the connection 

lost every now and 

then? Why are there 

sound interruptions?

The baby units may be out 

of range. Move the parent 

unit closer to the baby units 

(but not less than 1 meter / 

3 feet). 
Other electronic products 

may cause interference with 

your baby monitor. Try  

installing your baby monitor 

as far away from these  

electronic devices as  

possible.

The speaker volume is preset to 

Level 3 on the 

parent unit. You can adjust to your preferred 

sound level.
To adjust the speaker volume:

Press   to decrease the volume, and   to 

increase the volume.

•

If you continue to press   or 

 

even the 

volume reaches the minimum or maximum 

setting, the parent unit will sound once.
When the parent unit is in mute, the visual 

sound indicator will still indicate the sound 

detected from the baby unit.

•

•

Use only AAA 

alkaline batteries (not 

included).
Do not mix old and new batteries. Do not 

mix alkaline, standard (carbon-zinc) or 

rechargeable (ni-cad, ni-mh, etc) batteries.
When the batteries are installed, the 

parent unit turns on.
The parent unit does not support 

recharging.

•

•

•

•

Slide open the battery compartment cover.

1.
2.  Flip the ribbon across the battery 

compartment.

The parent unit is on standby mode when:

it is not connected to the AC power supply; and
there is no sound detected from the baby unit. 

The standby time varies depending on usage and 

the battery life. Full batteries can last up to 8 days.

Replace the batteries when:

LOW BATTERY light flashes on the parent unit.
The parent unit beeps twice every 30 seconds.
The batteries are properly installed into the 

parent unit, but the 

POWER/LINK light on 

the parent unit is off.

To clean and maintain this product:

Avoid putting it near heating appliances and devices 

that generate electrical noise (for example, motors or 

fluorescent lamps).
DO NOT expose it to direct sunlight or moisture.
Avoid dropping the product or treating it roughly.
Clean with a soft cloth.
DO NOT immerse the parent unit and the baby unit 

in water and do not clean them under the tap.
DO NOT use cleaning spray or liquid cleaners.
Make sure the baby unit and parent unit are dry 

before you connect them to the power supply.

This product operates with the maximum power 

allowed by the Federal Communications Commission 

(FCC). Even so, the baby unit and the parent unit can 

communicate over only a certain distance - which can 

vary with the locations of the baby unit, the parent 

unit, the weather, and the layout of your home.
When the parent unit is out of range, it will beep three 

times every 10 seconds and enter searching mode.
To improve reception, move closer to the baby unit 

(but not less than 1 meter / 3 feet).
