3.Note: The transmitter can be oriented horizontally or vertically. Tempo- rarily place the Extension Transmitter in the intended mounting position. Press the Test Button. If the plug-in chime sounds, continue with step 4. If the plug-in chime does not sound, go to the Troubleshooting section be- fore continuing with step 4.
4.With the Extension Transmitter still in the intended location, activate the existing door chime. If the plug-in chime sounds, proceed to step 7. If it does not sound, try different positions for the transmitter, or increase the microphone sensitivity (Figure 3) by turning the Microphone Sensitivity Adjustment clockwise. In some instances, it may be necessary to take the removable microphone out of the transmitter case, and mount it directly on the existing chime case or inside the existing chime case on a resonat- ing chamber (not on chime bars). Please noteÐthe microphone wires can be temporarily removed from the wire terminals (Figure 3) by loosening the terminals with a phillips screwdriver if wire routing through small open- ings in the existing chime cover is desired. There is a slot on the transmit- ter cover for the wires if an external mounting is required. Double-sided tape is provided to attach the microphone to your existing chime case.
