Thank you for purchasing our IK-1 baby monitor. Your unit has been manufactured
and checked under the strictest quality control to ensure that each unit leaves the
factory in perfect condition. If in the unlikely event you find any defects or have any
problem, please contact your dealer, our branch or service center.

Please read this manual carefully to obtain maximum performance and extended
service life from the unit.

Features

-  Voice activated transmitter
-  Indicator on receiver showing received signal loudness even when volume is turned
  down
-  Selectable two channels with crystal clear sound
-  Low battery indicator on transmitter and receiver
-  Subaudible private tone function minimize interference from other electrical devices
-  Transmitter and receiver can operate with either AA size batteries or 9V AC adapter

Power Supply

1. Operation from batteries

Turn the locking screw counter clockwise 90° and slide open the battery
cover in the direction as shown. Insert four UM-3/AA size batteries, observe 
correct polarity (+/-) indication. Install back the battery door and turn the 
locking screw clockwise 90° to lock the battery door in place.
N.B. For best performance, do not mix use old and new batteries or alkaline 
and rechargeable batteries.

OPERATION

1.  Set the transmitter Power ON-OFF switch  1  to ON position.
2.  Set the channel selector  2  to either CH1 or CH2 position .
3.  The Power On indicator  3  will light up green. If it becomes red or dim, the
 

batteries have run down and need to be replaced.

4.  Place the transmitter nearby the cot with the microphone  5  facing towards the
 

baby, preferably 1m away.

5.  Once the built-in condenser microphone  5  picks up any sound from the baby,
 

the transmitter will automatically switches into transmit mode and the transmit

 

indicator  4  lights up.

6.  When the baby stops making sound, the transmitter will return to standby mode
 

and the transmit indicator  4  goes off.

7.  Using the Channel Selector  9  on receiver, set to the same channel as the transmitter.
8.  Turn the Volume Control  8  to switch on the receiver at a reasonable distance
 

away from the transmitter. (Too close a distance will create feedback which cause

 

a screeching sound at the speaker). The Power On indicator  10  will light up

 

green, if it becomes red or dim, the batteries have run down and need to be

 

replaced.

9.  Whenever a signal is received, the receiver indicator 11  will light up. The louder
 

the voice, the brighter the indicator. This indicator is useful to monitor the baby

 

when volume of speaker is turned down.

10. In case you hear interference or static noises, change to another channel on both
 

the transmitter and receiver.

11. This baby monitor is incorporated with private tone feature, so static noises will
 

not be heard in the receiver under standby mode. However, it is necessary

 

that the transmitter and receiver have the same

 

private tone (as indicated by colour code in the

 

battery compartment) to communicate with

 

each other.

12. Both the transmitter and receiver can be carried
 

around using hand strap. To install hand strap

 

(purchased separately), follow diagram as shown.

Precautions

-  Use only 9V 100mA type AC adapters. Use of other AC adapter may cause damage
  to the unit.
-  When not using the unit for a long period of time, remove all battery from the
  transmitter and receiver to avoid battery leakage.
-  Disconnect the AC adapter from the wall outlet when the unit is not to be operated.
-  The unit is best performed within a temperature range of 0 °C to 40°C (22 F to
  104 F).
-  Do not leave the unit expose to direct sunlight for a long time or near any heat
  source, moisture and excessive dust environment.
