TRANSMITTER BATTERY REPLACEMENT
Replacement battery - 9 volt NEDA 1604 (Eveready 216 or equivalent).
The battery in the transmitter can be che cked or changed by removing the front
lower half of the transmitter. Refer to the directions under “accessing the code
switch” for battery replacement.
TO REPLACE OR ADD A SET
A replacement or new transmitter or receiver may be purchased by specifying
the Model Number and the RF frequency desig nated on the identification label.
The RF frequency is set at the factory and must not be ad justed in the field. The
digital code can be matched to the companion receiver or transmitter by
following the above procedure.
OPERATIONAL CHECK
To check operation, move ba c k a rea s onab le dis t an c e (a bout 50 fe et) and press
the transmitter button. Operation should be reliable at this distance but
environment and location of both the transmitter and receiver will affect the
range. If the transmit ter is st owed well o ut of sig ht, it may be necessary to
remove it from its mounting and hold near the windshield. Try different locations
and positions. If operation is still unsatisfactory, the problem maybe isolated by:
1 . Checking the door operator. If the door will not open when the wall button is
pressed, the problem is likely to be the operator. If the door will open by
pressing the wall button, but not when the radio control button is p ressed,
the problem is probably in the radios.
2. Replacing the transmitter battery.
If, after performing the above operational checks, the controls still do not
function, they should be returned to your dealer for repair or replacement or they
may be returned, postage prepaid.

GARAGE DOOR RADIO CONTROLS

WARNING:
•
Disconnect power before any installati on or repair
•
Wear safety glasses
Your MULTI-CODE Radio Controls are designed specifically to remotely
control a garage door from within an automobile and to give years of dependable
service without adjustment. The transmitter/receiver combination utilizes the
MULTI-CODE scheme which permits the selection of as man y as 1024 code
combinations of the owner’s personal choice.
Because all radio controls are set
with the even numbered switches in the “ON” positi on when they leave the
factory, it is recommended that a different code be selected and set at the
time of installation.
Please refer to the “Accessing the Code Switch” section for
instructions. The radio frequency (RF) portion of the controls, however, are
tuned to standard frequencies and are thoroughly tested at the factory. This
permits the addition or replacement of eit her the transmitter or the receiver by
specifying the Model Number and the RF frequency designated on the
identification label. No RF adjustments are needed nor should any be attempted.
RECEIVER INSTALLATION
The receiver is designed to mount directly to the operator. It can be remotely
installed if the operator terminal strip is not accessible, or if power for the
receiver is not obtainable from the operator. To direct mount the receiver, simply
loosen the terminal screws on the operator and insert the tw o-way lugs fr om the
receiver under the screw heads along with the wall button wires), and tig hten
the screws (See Fig #1).
Place the antenna (an 11 inch white wire) in a vertical pos ition as far from any
metal as possible.

For remote installation the receiver may be mounted near the operator head on a
joist or the ceiling by using the mounting tab. O rder Model 1092-06 adapter,
which permits connection between the operator terminal and the two-way lugs
on the receiver.
Slip on connectors at one end of the adapter connect to the flat side of each
spade lug on the receiver, and spade connectors at the other end connect to
the operator terminal. Connect the wires as follows:
(a) White wire to terminal “1” or “24v”
(b) Black wire to terminal “2” or “Relay”
(c) Red wire to terminal “3” or “Common” (“Radio Power”)
(d) Connect push button wires to terminal “1” and “2” (See Figure #2).
Where power for the radio receiver is not available from the operator order a
Model 1092-01 power transformer adaptor for connection between the
operator and the remote receiver.
ACCESSING THE CODE SWITCH
Using a small screwdriver, pry the rectangular hatch from the receiver for
access to the code switch. On the transmitter the entire front lower half of the
case is removable. Grasp the front lower half of the case near the bottom on
both sides and pull upward away from the transmitter, this will disengage the
lower end. Then pull down ward to remove the lowe r c over, this will expose both
the code switch and battery compartment. Set both switches to the code of your
choice, being sure both are set the same since a different set ting of just one
switch will prevent operation. The digital c ode is determined by the position of
10 small switches numbered 1 through 10 located in the receiver and
transmitter. Any combination of “on” or “off” positions can be selected by using
a pencil or ball point pen. (Note: The switc hes are in the “on” position when the
switch is depressed toward the number.) See Fig ure #3.
Once the codes have been set, check operation and reinsert the hatc hes.
TRANSMITTER INSTALLATION
The transmitter is completely self contained, including battery, and can be
operated while mounted in the car. It is supplied with a clip for attaching to the
sun visor, if desired. If the clip is u sed attach to the case by sliding it into the
recess provided on the back of the transmitter until the sm all dimple s fit int o the
holes in the clip.
CAUTION:
Keep the clip flat when push ing it into position so that is doesn’t
extend down into the case where it could touch the circuit board and cause
damage.
