• When the power is low, the status indicator 

starts to flash. Replace the battery in such 

cases, even if it is less than a year old.

• Low power may become the cause of false 

alarm.

• There is no need to readjust the TD-20U or 

the receiver after replacing batteries.

• Press s witch 1 of 

the receiver until 

the power indicator 

starts flashing.

• Press switch 2 to 

select the zone 

you wish to assign 

to the sensor.

• Wave your hand in front of the TD-20U to trigger it.

• Verity that the receiver 

has learned 

successfully by 

observing the zone 

indicators of the 

receiver. Zone 

indicators should hav

s

remain

topped flashing and

 continuously 

• After teaching all the 

transmitter codes (if 

you have multiple 

transmitters), return the 

receiver to normal 

operating status.

• Make sure that the 

receiver operates 

correctly with all the 

transmitters.

Cover the TD-20U until you are 

ready to teach the receiver. 

Unwanted detection can cause 

the TD-20U to be assigned to the 

wrong zone and override the data 

of other transmitters.

Does the status indicator light up when 

you walk in front of the TD-20U? 

If not, check to see whether the battery is inserted 

correctly. Otherwise try a new battery.
Is the detection area setting appropriate?

If not, fix the setup.

Is the status indicator flashing? 

The battery is old. Replace the battery.

Is the power indicator of the receiver lit? 

Is the receiver on? Check the wiring, power switch 

and connection.

The receiver does not respond to the TD-

20U. 

The TD-20U is not properly recognized by the 

receiver. Teach the receiver correctly.

The zone indicator of the receiver is on, 

but nothing happens. 

The receiver has not been properly setup. Refer to 

the receiver’s manual and verify the setting.

Is there anything blocking the 

transmission? 

Relocate the receiver and/or the TD-20U. Metal 

objects can shorten the effective transmission 

range.

A particular zone is malfunctioning.

This is probably the transmitter’s problem. Check 

the TD-20U using this zone.

Are there small animals in the area?  

Refer to the Pet Alley section in  4  DETECTION 

AREA PATTERN.

Does direct sunlight or light from 

automobiles enter the sensor window?

Reorient the TD-20U to avoid such light sources.

Is the TD-20U installed on a stable platform?

Relocate the TD-20U to a stable platform.

Is there anything that may cause rapid 

temperature change in the detection 

area? (e.g. stove)

Remove any objects that may cause rapid 

temperature change from the detection area.

Is there anything that may cause rapid 

temperature change of the TD-20U?

(e.g. air conditioner)

Relocate the TD-20U elsewhere.

Before contacting the supplier!

Remove the battery, then reinsert the same 

batteries and verify the TD-20U’s operation again.

• If the above solutions do not work, please contact your supplier for services.

FCC ID : DC9TD-20U

The changes or modifications not expressly approved by the OPTEX could void the user’s authority to operate the equipment.To comply 

with the FCC RF exposure compliance requirements, this device and its antenna must not be co-located or operating to conjunction with 

any other antenna or transmitter.Note: This equipment has been tested and found to comply with the limits for a Class B Digital Device, 

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a 

residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in 

accordance with the instruction, may cause harmful interference to radio communication. However, there is no grantee that interference 

will not occur in a particular installation. If this equipment dose cause harmful interference to radio or television reception, which can be 

determined by turning the equipment off and on , the user is encouraged to try to correct the interference by one or more of the following 

measures.(1)Reorient or relocate the receiving antenna.(2)Increase the separation between the equipment and receiver.(3)Connect the 

equipment into an outlet on a circuit different from that to which the receiver is connected.(4)Consult the dealer or an experienced 

radio/TV technician for help.

IC ID : 4012A-000000TD20U

Operation is subject to the following two conditions.(1)this device may not cause interference, and (2) this device must accept any 

interference, including interference that may cause undesired operation of the device.

To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically 

radiated power (e.i.r.p.) is not more than that permitted for successful communication.

3. Fasten the battery with the 

    battery clamp hook.

2. Attach the connector to the 

    battery.
