7 TEACH TRANSMITTER CODES TO RECEIVER "TEACH MODE"
The receiver must be taught this transmitter code before use. Refer to the receiver's manual for details.
1. Preparation of receiver
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.
5. Verification
* 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.

TROUBLESHOOTING
1. The system is not operating
Check the transmitter.
Does the status indicator light up when
you trigger the transmitter?
Is the status indicator of the transmitter flashing?
Check the receiver.
Is the power indicator of the receiver lit?
Have all the transmitter codes had been
taught correctly?
Is the volume setting correct?
Are there other high power appliances using the
same electrical power outlet?
The zone indicator of the receiver is on, but
nothing happens.
Is there anything blocking the transmission?
Are the zone indicators flashing slowly?
Check the repeater.
Is the power indicator of the TR-20U lit?
Have all the transmitter codes had been
taught correctly?
Are there other high power appliances using the
same electrical power outlet?
Is there anything blocking the transmission?
Are the channel indicators flashing slowly?
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.
A certain zone seem to malfunction.
Before contacting the supplier!
• If the above solutions do not work, please contact your supplier for services.

COMPLIANCE
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.
2. Activate "TEACH MODE"
Press switch 1 twice
within 2 sec to activate
"TEACH MODE".
The power indicator
light down and
channel indicator
starts to flash.

Channel 2
Press switch 1 to transmit the transmitter code
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.
Check to see whether the battery is inserted correctly.
If the battery is old, replace it with a new one.
The battery is old. Replace the battery.
Is the receiver on? Check the wiring and connection.
Teach the transmitter codes correctly. The system will
not operate without this process.
Is the volume set to "0"? If so, readjust the volume.
Please connect the receiver to a different electrical
outlet.
Check to see whether the terminal is properly
connected to other devices.
Relocate the receiver and/or the transmitter. Metal
objects can shorten the effective transmission range.
Follow directions in LOW BATTERY INDICATION of
the receiver's manual.
Is the TR-20U on? Check the wiring and connection.
Teach the transmitter codes correctly. The system will
not operate without this process.
Please connect the receiver to a different electrical
outlet.
Relocate the TR-20U and/or the transmitter. Metal
objects can shorten the effective transmission range.
Follow directions in 9 LOW BATTERY INDICATION.
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.
This is probably the transmitter's problem. Check the transmitter
that corresponds to that channel.
Go through the setups again after turning on the
power while holding down switch 1.

LOW BATTERY INDICATION
Channel indicator start slow flashing whenever the
corresponding transmitters have low battery.
Any operation cannot be done until one of operations
below are conducted.
1) Replace transmitter's batteries.
2) Press switch 2.
TR-20U will not need to relearn transmitter after replacing
the batteries.
