STEP 6 Add additional transmitters. Repeat Step 5 for each
transmitter used with this receiver. Be sure to press the
receiver’s program button each time a new transmitter or a
different transmitter button on a multi-button transmitter is
pressed.
If the LED doesn’t come on when the receiver’s program button is
pressed, the receiver’s memory is full (10 transmitters total). Use
the erase function (Step 9) to remove transmitters form the
receiver’s memory.
STEP 5 Program receiver. Momentarily press the receiver’s
program button (channel one or two). The red programming LED
will light if there’s room in the receiver’s memory for another
transmitter (10 maximum per receiver). The LED stays on for
about 5 seconds. A transmitter must be entered while the LED
is on. Press the desired transmitter button. The LED will flicker
indicating that the receiver has accepted the transmitter.
➥ NOTE: Be sure to press the receiver program button for less
than 2 seconds (any longer may erase memory.)
➥ WARNING! Door operator will not activate when the
receiver is being programmed from the transmitter, but the
door operator will activate the next time the transmitter is
activated after programming.
➥ NOTE: The programming LED also monitors radio signals
entering the receiver. It is common to see an occasional blink
from the LED. The LED will also light when any transmitter
tuned to the receiver’s frequency (programmed into the
receiver or not) is activated.
STEP 7 Review memory. Press and hold the receiver’s
program button (channel one or two) until the LED begins to flash
(about 3 seconds) and then release the button. Count the number
of flashes. The number of flashes equals the number of
transmitters programmed into that channel of the receiver.
➥ NOTE: Don’t hold down the programming button longer
than 5 seconds, the receiver’s memory for that channel will
be erased (Step 9).

STEP 9 Erasing receiver memory. Transmitters may be
erased from the receiver’s memory by pressing and holding the
receiver’s program button (channel one or two) for 5 seconds or
more. After the LED blinks (count of transmitters) it will blink one
more time for channel one and twice for channel 2 as the
receiver’s memory for that channel is erased. All transmitters
for each receiver channel are erased at the same time.

➥ NOTE: The same transmitter (or the same transmitter button
on multi-button transmitters) cannot be programmed into both
receiver channels one and two.
➥ NOTE: If the receivers LED flashes continuously when a
transmitter isn’t being activated, the receiver is too close to an
electrical noise source. Move the receiver away from the noise
source or call technical services for assistance.

IMPORTANT !!!
Linear radio controls provide a reliable communications link and fill an important need in portable
wireless signaling. However, there are some limitations which must be observed.
✶ For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as
Part 15 devices. As such, they have limited transmitter power and therefore limited range.
✶ A receiver cannot respond to more than one transmitted signal at a time and may be blocked by
radio signals that occur on or near their operating frequencies, regardless of code settings.
✶ Changes or modifications to the device may void FCC compliance.
✶ Infrequently used radio links should be tested regularly to protect against undetected interference
or fault.
✶ A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale
distributor or dealer, and these facts should be communicated to the ultimate users.
