Should you desire 10th Bit Closed a watertight connection, use a single length of 16 to 22 gauge jacketed cable. Transmitter ANTENNA INSTALLATION 10th Bit Open 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 choose the MULTICODE 1066 Coaxial Wiring Kit, which is available from LINEAR CORPORATION. Note that the external antenna coupling uses a TYPE F antenna fitting. If necessary, you may use TYPE F 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. CODING Before you begin to use your MULTI-CODE RECEIVER YOU MUST SET THE CODING SWITCH. In order to set the code, refer to figure 2. 1 2 3 4 5 6 7 8 9O N O F F FIGURE 2 To gain access to the switch, remove the top section of the cabinet, if you have not already done so, Using a pencil, or other similar device, move the code switches to set your house code. Positions one through nine on most MULTICODE transmitters are used to set the house code. NOTE: THE MULTI CODE 4120 TWO CHANNEL TRANSMITTER OR 4140 FOUR CHANNEL TRANSMITTER REQUIRES A DIFFERENT CODE SELECTION. REFER TO THE APPROPRIATE INSTRUCTIONS IF THERE IS ANY DOUBT AS TO CORRECT SETTING. Setting code switch 10 on your transmitter will determine channel one or channel two. If the number 10 DIP switch is set in the OPEN or OFF position, you have channel one, if the second channel is desired, then set the transmitter DIP switch number 10 to the CLOSED or ON position. We strongly urge that you avoid the following code schemes: ALL ON, ALL OFF, 2 4 6 8 on 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 arrangements. BE SURE TO SET THE FIRST NINE SWITCHES ON YOUR RECEIVER EXACTLY THE SAME AS THE TRANSMITTER. Be certain to check that each code is functional before completing the installation. ADDITIONAL INSTALLATION INFORMATION LINEAR CORPORATION has taken every possible precaution to make the 3021 Receiver as reliable as possible. The circuit board is coated with a special water resistant treatment. We think the following notes should be observed: • Be sure the unit is sealed from moisture, and, if at all possible, keep it away from direct moisture. • If you are using the 3021 Receiver, make sure the seal around the top of the cabinet and that the strain relief of the 3021 prevents moisture from entering. • In those installations where vibration may be a factor, be sure to use a fastening compound, such as LOCTITE O on the mounting screws to insure reliable mounting. • If this, or any other equipment is being used in a safety related device, be sure to test the entire system at the t...
