Installation Instructions Garage Door Opener Radio Controls Model 5040 (300 mHz) \ 5042 (310 mHz) Single Button Mini Transmitters Model 5050 (300 mHz) \ 5052 (310 mHz) Dual Button Mini Transmitters WARNING: •• Disconnect operator power before any installation or repair •• Always wear safety glasses Your Digi-Code radio controls are designed specifically to remotely control a garage door opener and to give years of trouble free service without adjustment. Because all radio controls are set with the even numbered switches in the “ON” position 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 “Setting 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 either the transmitter or the receiver by specifying the Model number and the RF frequency designated on the identification label. RF adjustments are not needed nor should any be attempted. SECTION #1 ACCESSING THE CODE SWITCH AND BATTERY COMPARTMENT The models 5040, 5042, 5050 & 5052 mini transmitter cases are made up of two halves which are held together by a small phillips head screw. Removing this screw will allow access to the code switches and the battery compartment ( see diagram #1 ). ( Diagram #1 ) SECTION #2 SETTING THE CODE SWITCHES ON THE MODEL’S 5040 AND MODEL 5042 SINGLE BUTTON MINI TRANSMITTERS Use your finger to slide the “code switch hatch” from the Digi-Code receiver or locate the code switches on the back of your Stanley operator. The digital code is determined by the position of the 10 small switches numbered 1 through 10 located in the receiver and the transmitter ( see diagram #2 ). Set both code switches to the code of your choice, being sure both are set the same since a different setting of just one switch will prevent operation. Any combination of “on” or “off” positions can be selected by using a pencil or a pen. (Note: The switches are in the “on” position when the switch is depressed toward the number.) We strongly urge that several coding schemes be avoided: ALL ON; 2,4,6,8,10, ON. These positions are similar to our or other manufacturers test positions, or are frequently used. Once the codes have been set, check operation and reassemble products. ( Diagram #2 ) ( Diagram #3 ) Model – 5040 (300mHz) or 5042 (310mHz) SECTION #3 SETTING THE ( “RECEIVER” ) CODE SWITCHES - TO WORK WITH MODEL 5050 AND MODEL 5052 DUAL BUTTON MINI TRANSMITTERS Use your finger to slide the “code switch hatch” from the Digi-Code receiver or locate the code switches on the back of your Stanley operator . On the transmitter, locate the phillips head screw on the bottom of the case, removing this screw will allow access to the code switches and the battery compartment ( see diagram # 4 & # 5 ). Model – 5050 (300mHz) or 5052 (310mHz) ( Diagram # 4 ) ( Diagram # 5 ) Before setting the receiver code switches, you will need to set the transmitter code switch on your model 5050 or 5052. We strongly suggest that you change the code from the factory setting to provide security for your own system, and to eliminate interference with neighboring systems. SETTING THE TRANSMITTER CODE SWITCH – MODEL’S 5050 & 5052 On the transmitter, locate the phillips head screw on the bottom of the case, removing this screw will allow access to the code switches and the battery compartment . Once you have done this, locate the code switch and set code switch positions 1 through 9 to your personal code scheme ( THE 10 TH POSITION SWITCH MUST BE SET IN THE CLOSED POSITION “ON”), (Note: The switch is in the “on” position when it is depressed toward the number.). We strongly urge that several coding schemes be avoided: ALL ON; 2,4,6,8,10, ON. These positions are similar to our or other manufacturers test positions, or are frequently used. SETTING RECEIVER #1 (WORKS WITH LEFT BUTTON ON TRANSMITTER) Use your finger to slide the “code switch hatch” from the Digi-Code receiver or locate the code switches on the back of your Stanley operator. Set the receiver code switch positions 1 through 9 to match the transmitter code switch. Then make sure that the 10 th position switch on receiver #1 is set in the closed position “ON”. The left button on the transmitter should now operate this receiver. Once the codes have been set, check operation and reassemble products. SETTING RECEIVER #2 (WORKS WITH RIGHT BUTTON ON TRANSMITTER) Use your finger to slide the “code switch hatch” from the Digi-Code receiver or locate the code switches on the back of your Stanley operator. Set the receiver code switch positions 1 through 9 to match the transmitter code switch. Then make sure that the 10 th position switch on receiver #1 is set in the open position “OFF”. The right button on the transmitter should now operate this receiver. Once the codes have been set, check operation and reassemble products. SECTION #4 TRANSMITTER BATTERY REPLACEMENT The battery in the transmitter can be checked or changed by locating the phillips head screw on the bottom of the case, removing this screw will allow access to the battery compartment. Replacement battery must be a 12-volt. 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 designated on the serial tag label. The RF frequency is set at the factory and must not be adjusted in the field. The digital code can be matched to the companion receiver or transmitter by following the “setting” procedures above. OPERATIONAL CHECK To check operation, move back about 50 feet and press the transmitter button. Operation should be reliable at this distance but environment and location of both the transmitter and receiver will effect the range. Try different mounting locations and positions in the vehicle. If operation is still undesi…

Model CR-5040 and Model CR-5050: The following calculations will demonstrate that the Models CR-5040 and CR-5050 garage door remote control transmitters comply with this requirement. Both of these devices operate on a fixed frequency of 300.0 mHz. The physical size of these devices is such that the nearest surface is approximately one cm from the radiating portion of the transmitter. Assuming a point source of ratiation, the radiated power is related to the field strength by the equation: E ={(30*P t ) 1/2 }/R where:E = field strength in V/m P t = radiated power in Watts R = distance in meters from the point source The test report contained elswhere in this report indicates compliance of these models with a 5,433 μV/m maximum radiated field strength at a measurement distance of 3 meters. Solving the equation above for P t at this distance, P t = {(E*R) 2 }/30 Using R = 3 meters, and a maximum field strength of 5.433 x 10 -3 V/m, the radiated power is calculated to be less than 8.9 x 10 -6 Watts, or 8.9 x 10 -3 mW. The area of shere with a radius of 1 cm is: A = 4πr 2 A = 4*π*1 = 12.5 cm 2 Conclusion: Using the above calculations, the radiated power per unit area at a distance of 1 cm is: P/A = (8.9 x 10 -3 )/12.5 = 0.7 x 10 -3 mW/cm 2 or more than 3 orders of magnitude below the limit requirement of 1 mW/cm 2 . 307 Robbins Dr. • Troy, Michigan 48083 • Tel: 248 589-3645 • Fax: 248 588-6801 Model CR-5042 and Model CR-5052: The following calculations will demonstrate that the Models CR-5042 and CR-5052 garage door remote control transmitters comply with this same requirement. Both of these devices operate on a fixed frequency of 310.0 mHz. The physical size of these devices is such that the nearest surface is approximately one cm from the radiating portion of the transmitter. The test report contained elswhere in this report indicates compliance of these models with a 5,821 μV/m maximum radiated field strength at a measurement distance of 3 meters. In a calculation similar to the one above, the maximum radiated power per unit area for these models at a distance of 1 cm is 0.8 x 10 -3 mW/cm 2 . Conclusion: Again, the radiated power per unit area is more than 3 orders of magnitude below the limit requirement of 1 mW/cm 2 .

307 Robbins Dr. • Troy, Michigan 48083 • Tel: 248 589-3645 • Fax 248 588-6801 Description of Operation Model CR-5040, Model CR-5050, Model CR-5042 and Model CR-5052: These transmitters are all remote control devices designed and manufactured for the purpose of radio control of garage door openers and other like devices. The physical size of these devices is such that they can be either hand held or visor mounted on the interior of an automobile or similar vehicle. Models CR-5040 and CR-5050 operate on a fixed frequency of 300 mHz and Models CR-5042 and CR-5052 operate on a fixed frequency of 310 mHz. Operation or actuation of all of these devices is controled by a simple electromechanical switch. Depressing the switch causes the transmitter to emit the radio signal and upon releasing the switch, the transmitter ceases to emit the radio signal. Two button models provide the capability for activating two remote control receivers. Personal coding of each device is provided by a small 10 position switch which is mounted on the printed circuit board. Access to this switch is provided when the cover of the transmitter is removed. 10 switch positions provide 1,024 personal code selections. All models are compliant with F.C.C. Part 15 Rules.
