OPERATION
We urge you to test your installation completely before putting it into operation. Testing this receiver with the rest of the system will save potential problems later on.
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 MULTI- CODE 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 treat- ment. 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.
Note that two channels will not receive at the same time. Each channel requires a distinct signal from a transmitter in order to become activated.
