1.Overview“TW-820T” (below referred to as “the transmitter”) is a Pokayoke (mistake prevention) slim transmitter thatrealizes an indoor communication distance of 100 meters by combining it with a Pokayoke receiver“TW-820R-***” series.
The transmitter can be attached to various Pokayoke-compatible tools to transmit work completion signals toreceivers wirelessly.
The transmitter can also communicate with a Pokayoke receiver “TW-800R-***” series.
<Features>◆Reliable communication
The transmitter can communicate automatically by selecting the channel from 76ch in 2.4GHz bandwidth.
The transmitter transmits the signal reliably by 2way communication.
◆The lighting / blinking transmitter LED indicates wireless communication OK/NG.
◆Communication status notification
The LED indicates wireless communication status of the use environment.
◆Battery level notification function
LED indicates battery replacement is required.
◆Uses a small and lightweight coin battery as a power source.
◆Easy battery replacement◆Battery life of about 750,000 uses. (depending on usage conditions)◆Communication distance of approx.50m~100m indoors (varies depending on receiver andoperating environment).
◆Available countries：Japan, Canada, USA, China Thailand, Vietnam, and India.

*TW-820R is only available in Japan. In the case of using transmitter TW-820T outside of Japan, use it withthe receiver TW-800R or TW-800R-***.

5.Attachment of TW-820T<Attachment to wrenches>①Attachment of the harness connector with limit switch
The harness connector is attached to the transmitter at factory. When it is removed for maintenance orreplacement, securely connect the harness connector with limit switch so that the black cable sits on the outerside, as shown below.
The connector cannot be inserted in the wrong orientation.

②Attachment of the limit switch to the wrench base
Fix the limit switch to the wrench base by using the two supplied limit switch fixing bolts and flat washers.
When operating the wrench, make sure the movable range of the wrench lever matches the working range ofthe limit switch.

The hex socket head cap bolt requires a washer.
Apply screw lock agent to the bottom 2 to 3 threads of thehex socket head cap.

Wrench base

Limit switch

Wrench lever◆The attention and the check method on limit switch attachment
When the wrench lever working range of a wrench is small, a limit switch cannot be struck and a transmitter
may not send. In limit switch attachment, be careful enough and carry out.
It is recommended to check the attached condition of the limit switch by using a tester.
9

TW-820T③Attachment of the transmitter
To prevent the harness of the limit switch from getting caught in the case, limit switch or screw, use the mounting
holes of the main body case and fix the transmitter with the two supplied slim head small screws (M4 screws).

[Caution!]

The dimensions of main body mounting holeare different from dimensions of hole ofbracket on TW-800T.
Therefore, please note that some wrenches
cannot be installed.

〇

×
The harness is caught between the limit
switch, screws, etc. and the case.

10

TW-820T<Input Judgment time for transmitter>
The transmitter is designed not to transmit signals when the signal input time from the limit switch is 40ms orless. This prevents the transmitter from accidentally transmitting signals when dropping the wrench.
Due to the above mechanism, the transmitter may not transmit signals even after hitting the limit switch withyour finger, etc. for transmitting test signals.
<Insertion or removal of the battery>
To close the battery cap, turn the battery cap securely in the direction of arrow shown below until it snaps into
place.
To remove the battery cap, turn the battery cap in the opposite direction from the arrow shown below.

When replacing the battery, be sure to insert the coin battery with the correct polarity.

6.Setting
The transmitter and a Pokayoke receiver TW-800R-*** or TW-820R-*** need to be paired before use.
By pairing them, they recognize an identification signal from each other and communicate with each other.
This manual describes how to pair the transmitter with the receiver TW-820R.
For pairing with a receiver other than TW-820R, see the instruction manual of each receiver.
⚫ Pairing (registration)①Press the lighting switch for paring of the receiver, and turn ON the power switch at the same time.
The lighting switch for paring blinks and the receiver enters the pairing mode for 10 seconds.

Lighting switch for paring
Pairing switch(Test switch)

Power switch②Long press the pairing switch of the transmitter for 3 seconds or longer.
③The lighting switch for paring of the receiver goes out and pairing is complete.
④Turn OFF the power of the receiver once and turn it ON again, and the receiver can communicate with thepaired transmitter.
⚫ Reset pairing①Press the lighting switch for paring of the receiver, and turn ON the power switch at the same time.
The lighting switch for paring blinks and the receiver enters the pairing mode for 10 seconds.
Long press the lighting switch for paring for 2 seconds or longer, and the lighting switch for paring lights
up and the paired (registered) data of the transmitter is deleted.
◆Notes
A long press on the pairing switch of the transmitter (3 seconds or more) when the receiver is not in the pairing
mode resets the pairing with the receiver and prevents communication with the registered receiver. When pairing
is reset by mistake, perform the pairing procedure again.

7.How to Use the transmitter①Turn ON the power switch of the receiver.
Make sure the receiving LED is OFF.
When the receiving LED lights up, the transmitter is not paired. Pair the receiver and transmitter.

Receiving LED (Green)(Lighting switch for paring)

Monitor LED (green/red/yellow/orange)②A wireless signal is transmitted by turning the limit switch ON.
When wireless communication is normally executed, the receiver generates a relay output and the buzzer of thereceiver is activated according to the settings.
The green LED of the transmitter blinks once.
When the communication is not executed normally, the receiver is not activated.
The red LED of the transmitter blinks 10 times.
While the receiver is generating a relay output or preventing a double count, the receiver returns a BUSY signal
to the transmitter. Upon receiving the BUSY signal, the green LED of the transmitter blinks 4 times.

TW-820T●Test switch
The transmitter is equipped with a test switch for checking the communication status.
When the transmitter transmit the signal by test switch not limit switch, receiver doesn’t output relay output. But
LED of receiver only turns on.
The test switch also can be used as a pairing switch. A long press on the test switch (3 seconds or more) resets
the pairing with the receiver and prevents communication with the registered receiver. When pairing is reset by
mistake, perform the pairing procedure again.

When the battery level becomes low and the battery needs to be replaced, the blinking green LED after signaltransmission turns into blinking orange.
When the orange LED blinks, please replace it with a new battery immediately.
When you replace the battery with a new one, the LED on the transmitter will return to green from the second andsubsequent transmissions.

When the battery needs to be replaced, the blinking green LED
after signal transmission turns into blinking orange.

TW-820T●Communication status notification
When your wireless communication is not good, the blinking green LED after signal transmission turns into
blinking yellow.
The transmitter can be used even when the yellow LED is blinking. However, there is higher possibility thatwireless communication will fail.
When the yellow LED is blinking, consider taking measures, such as “Improve the installed condition of thereceiver antenna”, “Remove obstructions between the transmitter and the receiver”.
When wireless communication is improved, the blinking yellow LED of the transmitter turns back to blinking green.
