TROUBLESHOOTING

• Check the device by referring to the table below. If you cannot restore the device to 

normal condition after the check, contact the place of purchase or TAKEX.

Maintenance

To clean the device, use a soft, wet cloth and then wipe off any water drops.
If the device is particularly dirty, dip the soft cloth in the water that contains a weak neutral detergent. Wipe the device gently with the 
cloth, then wipe off any detergent that remains. Do not use substances such as thinner or benzene. (The plastic parts may deform, 
discolor or change their properties.)
Perform operation checks on a regular basis.

(11)MODE SELECTOR FUNCTION

Mode selector

Alignment

Operate

(Factory set)

Note: Installed on the transmitter and the receiver

This mode is used for operation, which is to minimize LEDs’ lighting up, and 
reduce consumption.
And also optimizes the transmission beam strength.

This mode is used for adjustment, which is to light up the LED for adjustment, 
and optimize the transmission beam strength.

When adjusting beam alignment, please select “Mode selector” to “Alignment” 
on both the transmitter and the receiver in order to adjust the beam alignment 
accurately.

After adjustment, make sure to return “operate” mode

Status

Cause

Countermeasure

Transmitter LED does not light up
(when the cover is open)

(1) Batteries are not placed in the transmitter
(2) Batteries in the transmitter are exhausted
(3) Batteries in the transmitter are placed with opposite 

polarity.

(4) Connection failure or disconnection between the main 

unit and base

(5) Transmitter is set to  “No transmission”.

(6) The Mode selector is set to “Operate”.

(1) Mount batteries in the transmitter
(2) Replace batteries in the transmitter with new ones
(3) Correct the battery polarity in the transmitter

(4) Check connection

(5) Press the upper/lower changeover switch, and set to 

“Transmit”

(6) Set the Mode selector to “Alignment”.

Reception authorization LED does 
not light up

The Mode selector is set to “Operate”.

Set the Mode selector to “Alignment”.

Alarm LED does not light up when 
the infrared beams are interrupted

(1) Batteries are not placed in the receiver
(2) Connection failure or disconnection between the main 

unit and base

(3) The 4 beam paths are not interrupted simultaneously
(4) Interrupted for shorter time than the detection 

response time

(5) Infrared beams are refl ected on any object, and enter 

into the receiver

(6) Other beams enter into the receiv

(7) Strong light or sunlight directly enter the optical 
     axis of receiver. (Such as headlight of vehicle, IR
     illumination, the white light LED, etc.)

er

(1) Mount batteries on the receiver
(2) Check connection

(3) Interrupt all 4 beam paths simultaneously
(4) Set a shorter detection response time than the 

passing time

(5) Remove refl ective objects, or change the installation 

place and/or optical axis direction

(6) Change direction of optical axis to prevent other beams 

(7) Switch location of receiver and transmitter.

from entering
Alternatively, change the frequency channel settings

Alarm LED continues to light
(Alarm output does not stop)

(1) Optical axis (focus) is misaligned
(2) There are obstacles between the transmitter and 

receiver

(3) Covers or refl ecting mirrors of the transmitter and 

receiver are dirty

(4) Frequency channel settings of the transmitter and 

receiver do not match

(1) Readjust the optical axis
(2) Remove obstacles

(3) Clean with a soft cloth

(4) Match the frequency channel settings

Alarm is often generated 
intermittently

(1) Batteries are exhausted
(2) Connection failure or disconnection between the main 

unit and base

(3) There are obstacles between the transmitter and 

receiver (trees blowing in the wind)

(4) Sensor installation is unstable
(5) Covers or refl ecting mirrors of the transmitter and 

receiver are dirty

(6) Optical axis (focus) is misaligned
(7) Big birds or cats sometimes interrupt the beams

(8) Protection distance is longer than the protection 

(9) Strong light or sunlight directly enter the optical 
      axis of receiver. (Such as headlight of vehicle, IR 
      illumination, the white light LED, etc.)

distance setting on the transmitter

(1) Replace batteries with new ones
(2) Check connection again

(3) Remove obstacles

(4) Fix the sensor securely
(5) Clean with a soft cloth

(6) Adjust the optical axis again
(7) Set the detection response time to be slightly longer

(Except the place where intruders can run through

at full speed)

(8) Change the setting according to the protection 

(9) Switch location of receiver and transmitter.

Alarm LED lights up, but the 
wireless transmitter does not 
operate

(1) Wiring to the wireless transmitter is disconnected
(2) Wiring to the wireless transmitter is wrong

(1) Check connection again
(2) Check connection again
