Optex TR-20U User manual

2000
Reception/Transmission range must be changed according to environment.
Please check if system works properly for the site.
In the case of insufficient transmission range, add another TR-20U (Repeater unit) to
extend range.

Wall Mounting
Use the mounting screw
on a wall. Leave some
length of the screw out
for mounting hole of the
TR-20U.
Desktop
Pull out the stand on the back
of the TR-20U and place it on
any flat surface.
Note:
・Verify that each transmitter has been successfully learned by TR-20U by triggering them.
・Single transmitter cannot be learned by multiple channel.
・TR-20U learned code will keep memorized even if turning OFF the power.
Erasing codes from TR-20U’s memory.
1) Hold down switch 1 until the power indicator starts to flash.
2) Press switch 2 until the appropriate channel indicator is lit.
3) Press switch 1 to erase. Channel indicator will start to flash.
4) Press switch 2 a few times until the power indicator stops flashing and remains lit.
A) The TR-20U automatically
starts in “LEARN MODE”
if no transmitter code has
been programmed.
OR
B) Press and hold switch 1
until the power indicator
starts to flash.
Use only the power adaptor supplied with the
product.

(Hand-Held Transmitter), TC-10U(Door/Window Transmitter) and also compatible with any units of
WIRELESS1000 series.
・Identifies the channel (location) by LED lights (4 channels).
・Able to learn 4 transmission codes.
・Automatic “Learning” function facilitates to preset transmission codes to TR-20U.
・Over 8 million codes possible, eliminates interference from neighbors.
・Low battery indicator to recognize transmission units’ battery status.
・Powered by a 9VDC adaptor(Included).
Erasing all codes from TR-20U. (Return to the factory default)
To erase all programming, turn on power while holding switch 1.
CAUTION
1. Impact/Shock
Impact or Shock can cause severe damage or break the TR-20U.
2. Electric Devices
Use TR-20U at least 3ft (1m) away from electronic devices such as TVs, Radios,
PCs, Microwave ovens, or any other device with an electric motors.
This may cause the unit to malfunction.
3. Transmission range
Transmission range may decrease under the following conditions:
- Either transmission units or TR-20U installed on a metal surface.
- Presence of a steel door, reinforced concrete or other metal obstructions between
transmission unit and TR-20U.
- Places near strong radio sources such as broadcast stations or substation.
4. Cleaning
Harsh cleaners such as paint removers or benzene may ruin the surface. Use a soft wet
cloth and mild soap to clean.
WARNING
1. Harsh environments
Do not use the TR-20U outdoors, severe conditions as out of warranted
temperature, rapid temperature change, high humidity, or steam.
This may cause the unit to malfunction.
2. Tampering
Any changes or modifications not expressly approved by OPTEX could void the user’s
authority to operate the equipment.
3. Adaptor
Do not use any other AC adaptor except what is included.
Each transmitter has a unique transmitter code which can be automatically learned by TR-20U.
The TR-20U’s channels must be taught to respond to the appropriate transmitter. (No transmitter is taught on default setting.)

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.
