Ultra-Small Receiver Installation, Cont’d

Programming Procedures

NOTE: Prior to programming, make
sure the receiver’s LED blinks red
when power is applied. If  the
receiver’s LED is not blinking red,
disconnect then reconnect the power.

Programming transmitter(s) into
the receiver’s memory:

The receiver can learn up to 12
transmitters. Follow the steps below
to program your receiver. Repeat
steps 1-3 for each transmitter.
1. Press the receiver’s programming

button for less than 2 seconds
and release. The LED should
change from blinking red to solid
green, indicating the receiver has
entered its programming mode.

2. Activate and release the

transmitter once and confirm
that the receiver’s LED changes
to solid red. This indicates the
receiver is learning the
transmitter’s code.

3. Wait a few seconds and then

activate the transmitter a second
time. The receiver’s LED should
now blink green several times
indicating that it is ending its
learning procedure. When the
procedure has ended, the LED
should be blinking red.

Programming the receiver’s
output activation time:

When the receiver is activated, its
outputs will stay in the minimum
activation state for approximately 1.5
seconds (default). This time can be

adjusted to stay in the activation state
for up to 4 hours. Follow the steps
below to adjust the receiver’s output
activation time.
1. Press the receiver’s programming

button for 4 seconds and release.
The LED should be solid red.
This indicates the receiver is in
the activation time programming
mode.

2. Activate and release the

transmitter.

3. When the desired time has

elapsed (up to 4 hours) activate
the transmitter again. The
receiver’s LED should blink
green several times indicating it is
ending the procedure. When the
procedure has ended, the LED
should be blinking red.

The receiver and transmitter comply with FCC part 15/15.231-2001, Industry Canada RSS-210-2003, EN55022A-2000, EN55024-2001, EN300-220-3 V1.1.1-2000, and EN301-489-1
V1.2.1-2000. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any inerference received,
including interference that may cause undesired operation. This product may be susceptible to local transmissions being generated near the transmitter’s fundamental frequency.
Testing has shown some susceptibility in a frequency range of 416-440 MHz.

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 instructions, may cause harmful interference to radio communications. However, there is no guarantee 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
interference by one or more of the following measures: (a) Reorient or relocate the receiving antenna. (b) Increase the separation between the equipment and receiver. (c) Connect the
equipment into an outlet on a circuit different from that to which the receiver is connected (d) Consult the dealer or an experienced radio/TV technician for help.

The user is cautioned that any internal modifications, either replacement of or modification of any component, of the transmitter or receiver could violate the rules of compliance and
authority to operate the equipment.

Deleting all transmitters from the
receiver’s memory:

You can clear the receiver’s memory
of  all previously learned transmitters
by following the steps below. NOTE:
Deleting previously learned
transmitters does not change the
receiver’s output activation time.
1. Press the receiver’s programming

button for more than 8 seconds
until the receiver’s LED starts
blinking green. Release
the programming button. The
LED should now be blinking red.

2. The receiver’s memory is now

cleared. To learn new
transmitters, follow the steps for
programming transmitters into
the receiver’s memory.
