IF YOU HAVE THE MODEL 1099-40: The red wire  
will go to the positive 12 volt terminal in the operator. The  
black wire will go to the negative terminal or ground  
terminal of the operator. Connect the two gray wires as  
specified by the manufacturer of your operator. If such  
instructions do not exist, wire the two gray wires in  
parallel with the pushbutton terminals (see figure 4).

Begin your installation of the 1099 by correctly wiring the  
receiver to the devices you will be using. WE URGE YOU  
TO BECOME FAMILIAR WITH THE INSTRUC-  
TIONS THAT THE MANUFACTURER OF YOUR  
EQUIPMENT HAS PROVIDED. SINCE, IN  
MANYCASES, THESE INSTRUCTIONS WILL DETER-  
MINE THE WAY IN WHICH THE 1099 RECEIVER  
WILL BE INSTALLED.  
1. The antenna must be connected to the receiver for  
normal use.  
Installation Instructions  
2. If the opener fails to operate, check to see that 115 VAC  
power is present. Check circuit breakers or for a system  
power failure.

RADIO CONTROLS  
3. If the opener operates by pressing the wall button, but  
not when the transmitter button is pressed, the radio  
controls are probably at fault. Check to make sure  
both transmitter and receiver code switches are set  
to the exact same code since a difference of just one  
switch will prevent operation. Check transmitter bat-  
tery, location of the transmitter and receiver installation.

The receiver should be mounted near the opener power  
head and can be installed in any position by using screws  
and the two slots in the cover flanges. Select a location and  
position that permits access to the terminals and space for  
the antenna as clear of metal structures as possible and  
preferably in a vertical position.

Disconnect power before any installation or repair.  
Wear safety glasses.  
Your Multi-Code Radio Controls are designed specifically  
for the remote control of industrial door or gate openers  
and to give years of dependable service without  
adjustment.  
4. Try mounting the antenna at a more favorable remote  
location by utilizing the coaxial kit.

IF YOU HAVE THE MODEL 1099-20: Plug the trans-  
former into a convenient 115 volt outlet. Connect the  
remaining gray wires as specified by the manufacturer of  
your operator. If such instructions do not exist, wire the  
two gray wires in parallel with the pushbutton terminals. If  
the operator has a three wire terminal, the proper terminals  
will usually be marked “1” and “2” or “24V” and  
“RELAY” (see figure 2).  
If, after performing the above operational check, it is  
necessary to return the radio controls, return both the  
transmitter and receiver to your dealer for repair or  
replacement or they may be returned, postage prepaid,  
directly to Linear Corporation.  
Before you continue to read these instructions, note that  
there are 3 versions of the model 1099 receiver. The model  
1099-20 uses a 115-24 volt transformer. The model  
1099-40 comes with 4 wire connections for use with  
12VDC systems. The model 1099-30 comes with 4 wire  
connections for use with 24VAC systems. In addition, if  
you should choose to cut the transformer away from the  
1099-20, this modified product MUST ALSO BE WIRED  
TO 24VAC ONLY.  
At this point you should mount your 1099 receiver to its  
permanent installation, if you have not already done so.  
ANTENNA INSTALLATION  
WARRANTY  
After you have mounted your receiver, test it with the  
enclosed antenna for range, noting the coverage that you  
get from all desired operating locations. If greater range or  
coverage pattern is necessary, you may need the 1066  
Coaxial Wiring Kit, which is available from your dealer.  
Note that the 1099 external antenna coupling used a TYPE  
BNC antenna fitting. If necessary, you may use a TYPE  
BNC to TYPE F adapter, allowing you to use fittings found  
where television antennas are sold, along with 75 ohm  
antenna wire. It is not advisable to use lengths greater than  
20 feet, as this may affect range or tuning.

SELECTING A CODE  
GRAY  
RELAY  
The code is determined by the positions of the 10 small  
switches numbered 1 through 10 located on the receiver  
board. To gain access to the switch, remove the top section  
of the case. Any combination of ON (CLOSED) or OFF  
(OPEN) positions can be selected by using a small  
screwdriver or ball point pen (see figure 1). We strongly  
urge that you avoid the following code schemes: ALL ON,  
ALL OFF, 2, 4, 6, 8, 10, on or 1, 3, 5, 7, 9, on. These codes  
are frequently used by other manufacturers, and create the  
possibility of false operation, and may be less secure than  
other code schemes.

ADDITIONAL INSTALLATION INFORMATION  
IF YOU HAVE THE MODEL 1099-30: Wire the red and  
black wires to a 24VAC power supply. Connect the  
remaining gray wires as specified by the manufacturer of  
your operator. If such instructions do not exist, wire the  
two gray wires in parallel with the pushbutton terminals. If  
the operator has a three wire terminal, the proper terminals  
will usually be marked “1” and “2” or “24V” and  
“RELAY” (see figure 3).  
Linear Corporation has taken every possible precaution to  
make the 1099 receiver as reliable as possible. We think  
the following notes should be observed:  
1. Be sure the unit is sealed from moisture, and, if at all  
possible, keep it away from direct moisture.  
CAUTION: Any changes or modification in intentional or  
unintentional radiators which are not expressly approved  
by LINEAR CORPORATION could void the user’s author-  
ity to operate this equipment. This applies to intentional  
and unintentional radiators certified per Part 15 of the  
F.C.C. rules and regulations.  
Be certain to check that the code is functional before  
completing the installation.  
2. In those installations where vibration may be a factor,  
be sure to use a fastening compound, such as LOCTITE  
(TM) on the mounting screws to insure reliable  
mounting.

To check operation, move back a reasonable distance  
(about 50 feet) and press the transmitter button. Operation  
should be reliable at this distance but environment and
