1. Oloa Ua Ovaview

The Linear MCS412001 Multi-Code 2-Channel Visor Transmitter is designed for use with automatic door and gate operator applications. This portable transmitter features raised dimples on its buttons for easy identification, including for vision-impaired users. It operates on a 9-volt battery and includes a visor clip for convenient mounting.

The transmitter utilizes a multi-code format with two 10-position coding switches, offering 1,024 possible codes per channel. This allows for independent coding to activate different devices, such as a common gate and a private door. The transmitter will only activate receivers that are set with the identical code.

2. Setup and Coding Instructions

Before placing your transmitter into service, it is essential to set your codes to ensure security and prevent interference with neighboring systems. The model 4120 transmitter features two 10-position coding switches. Avoid using several common coding schemes (e.g., ALL ON, ALL OFF, 2, 4, 6, 8, 10 ON; 1, 3, 5, 7, 9 ON) as these positions are frequently used or similar to other manufacturers' test positions.

Setting the Code Switches:

1. Open the transmitter case to access the coding switches.
2. For a single receiver: Set the ten position switch on the transmitter to match your receiver's code.
3. For two single channel receivers: Set the ten position switch on Side A of the transmitter to match your first receiver (#1). Set the ten position switch on Side B of the transmitter to match your second receiver (#2).
4. For a MULTI-CODE™ 3021 or 3028 two-channel receiver: Set the receiver and transmitter (Side A and B) code switch positions 1-9 to match. The 10th position on your transmitter code switches is used for channel selection. Channel 1 on the receiver is selected by moving the 10th position of the transmitter side A to the OFF (open) position. Channel 2 is selected by moving the 10th position of the transmitter side B to the ON (closed) position.
5. Once the codes have been set, check the operation and replace the lower cover.

Fa'apipi'i Transmitter:
