1. The system is not
operating
Check the transmitter.
Does the status indicator light up when
you trigger the transmitter?
Check to see whether the battery is inserted correctly.
If the battery is old, replace it with a new one.
Is the status indicator of the transmitter flashing? The battery is old. Replace the battery.
Check the receiver.
Is the power indicator of the receiver lit? Is the receiver on? Check the wiring and connection.
Have all the transmitter codes had been
taught correctly?
Teach the transmitter codes correctly. The system will
not operate without this process.
Is the volume setting correct? Is the volume set to “0”? If so, readjust the volume.
Are there other high power appliances using the
same electrical power outlet?
Please connect the receiver to a different electrical
outlet.
The zone indicator of the receiver is on, but
nothing happens.
Check to see whether the terminal is properly
connected to other devices.
Are the zone indicators flashing slowly? Follow directions in LOW BATTERY INDICATION of
the receiver’s manual.
Are there other high power appliances using the
same electrical power outlet?
Please connect the receiver to a different electrical
outlet.
Are the channel indicators flashing slowly? Follow directions in 9 LOW BATTERY INDICATION.
Is there anything blocking the transmission? Relocate the receiver and/or the transmitter. Metal
objects can shorten the effective transmission range.
Is there anything blocking the transmission? Relocate the TR-20U and/or the transmitter. Metal
objects can shorten the effective transmission range.
2. The system is not operating correctly.
The TR-20U does not learn the transmitter
codes.
The TR-20U gets reception in the wrong channel.
Check whether the transmitter codes have already
been “learned” in a different channel. If so, erase the
memory and teach again.
Erase memory in the channel in which the RC-20U responds
and teach using the correct channel.
A certain zone seem to malfunction.
This is probably the transmitter’s problem. Check the transmitter
that corresponds to that channel.
Before contacting the supplier! Go through the setups again after turning on the
power while holding down switch 1.
•If the above solutions do not work, please contact your supplier for services.

FCC ID : DC9TR-10U
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 does 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 : 4012A-000000TR20U
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.

The receiver must be taught this transmitter code before use. Refer to the receiver’s manual for details.
1. Preparation of receiver
5. Verification
2. Activate “TEACH MODE”
OPERATION CHART for teaching TR-20U’s code to the receiver.
3. Select channel you wish to teach
TR-20U will automatically return to normal operation after 5 seconds without any operation.
Verify that the receiver has learned successfully by observing the channel
indicators of the receiver. Channel indicators should have stopped flashing and
remain continuously on.
* It will be skipped if no
transmitter code has
been programmed in
channel.
TR-20U starts
in channel 1.
Press switch 2 to advance to the
next channel.
Press switch 1 to transmit the transmitter code
Press switch 2 to return to

Press switch 1 of the
receiver untill the power
indicator starts flashing.
Press switch 2 to select
the zone you wish to
assign to the TR-20U.
*Note
Receivers compatible
with TR-20U are RC-20U
of WIRELESS 2000
series and RC-10U/RG-
10U of WIRELESS 1000
series.
* After teaching all the
transmitter codes (If you
have multiple transmitters),
return the receiver to normal
operation status.
* Make sure that the
receiver operates correctly
with all the repeaters and
the transmitters.
Note:
Make sure to teach
TR-20U’s code to the
receiver after teaching
transmitter code to the
repeater.
Press switch 1 twice
within 2 sec to activate
“TEACH MODE”.
The power indicator
light down and
channel indicator
