transmitter at least once annually, prior to each operational season. The key fob battery can be
changed by simply removing the small screw on the back of the unit, and splitting the transmitter case.
Once the case is open, slide the battery out of the battery holder, and replace. It is important to be
delicate during battery replacement so no damage to the unit occurs; especially with regard to the
solder points where the metal battery holder connects to the transmitter board. Electrostatic discharge
and/or contacting internal electronic circuitry with metal tools can cause damage to components as
well. For this reason, no screwdrivers or other hand tools should be used inside of the transmitter case.
Upon reassembly, make certain that the gray keypad is seated securely in the sealing channel. If this is
not done properly with care, the unit may be susceptible to water damage. To seat the pad properly,
once the battery is changed, position the keypad over the transmitter board, and ensure proper
alignment. Place the top half of the transmitter casing (the side with four button holes) down over the
entire assembly. VERY IMPORTANT: DO NOT PLACE THE RUBBER KEYPAD IN THE TOP HALF
OF THE CASING BEFORE REJOINING THE TWO HALVES; PLACE THE RUBBER KEYPAD OVER
THE BOARD, THEN PLACE THE TOP HALF DOWN OVER THE ENTIRE ASSEMBLY. Following the
above procedure will result in a proper seal and ensure quality protection against environmental forces
Rx/Tx Communication/Learning:
When purchased, the communication between the transmitter and the receiver unit will already be
established. Once powered up, the unit should function properly with no further action required. (see
the table below for the exact operational characteristics of your configuration) Occasionally during your
period of ownership, there may be times when it is necessary to reestablish the wireless
communication between the transmitter and the receiver unit. This process is accomplished by
“learning” the transmitter into the receiver unit. It may be necessary to perform this action after
extended periods of storage, long periods of inactivity, or after transmitter replacement. This action can
also be used as a troubleshooting measure whenever communication between the transmitter and
receiver unit has been lost. (Do this procedure only after the initial troubleshooting measure of
transmitter battery replacement has been completed) Each transmitter generates a unique signal, and
your receiver unit needs to be able to identify and respond to that signal in order to operate. The use of
a unique signal for each transmitter prevents your receiver from being susceptible to outside
interference, and protects against stray signals causing potentially undesirable operation. Some
customers prefer to have multiple transmitter controls for their units. Each RE3 is capable of handling
and responding to multiple (up to five) transmitters; you simply have to “learn” in each transmitter to
your receiver unit. (Additional transmitters are available through your provider, or through Rowe
Electronics - 515-264-1808) To complete the learn procedure, simply do the following. Power up the
unit. When you do so, the LED on the receiver unit will flash RED four times. This indicates that the unit
has received power. There is magnetically controlled switching circuitry embedded into the receiver
unit, and this magnetic circuitry switches the receiver into its “learn” mode. To operate, place a fairly
powerful magnet over the receiver “learn” area (see the diagram below for the learn location) for a brief
moment (3 seconds), and then remove it. YOU MUST USE A FAIRLY POWERFUL MAGNET. Upon
detecting the magnetic field, the LED will go to a constant RED state. If the LED does not go to a solid
red state, try again. If that fails, chances are your magnet is not powerful enough. Due to the position
of the magnetic switch inside of the receiver case (it’s closest to the side and bottom of the case), you
may also try waving the magnet on the side or on the back of the receiver case (at the learn area
shown below). Doing so will get your magnet as close as possible to the magnetic switch. Once the red
light goes to a solid state, immediately press any button on the transmitter you are attempting to learn
in. The LED will respond to your button press. (should go to a GREEN\YELLOW color). This confirms
that the receiver has picked up a signal from the transmitter, and has subsequently decoded and
memorized that signal. Communication has been established between the transmitter and receiver, and
it is now be ready to function properly. Should the above procedure not complete successfully, wait until
the LED light goes out, and repeat the procedure. If for any reason you experience a second failure of
