Installation
Note: Positioning the transmitter or Door Chime on or near metal structures or other metallic
objects or doorframes may reduce the transmission range.
Pushbutton Transmitter
You can attach the transmitter directly onto your doorframe using the adhesive pad. Make
sure the surface on which it is to be placed is clean and dry. Alternatively open the front
cover using a flathead screwdriver (Illustration 1) and mount using the screws provided (See
Illustration 2), ensuring that the rubber grommets remain in place.
To ensure weatherproofing is maintained, always mount the Transmitter in the upright
position shown in Illustration 2 and replace the front cover securely.
When the Transmitter button is pressed, the Indicator Light (A on Illustration 1) will
illuminate to show that the Transmitter is working. When it does not illuminate, the battery
needs to be replaced. Use a CR2032 Lithium Coin Cell battery, inserting it as shown in
Illustration 3.
Door Chime Receiver
Remove the battery compartment cover and insert the two (C size) alkaline batteries as
shown in Illustration 4.
