transformer separately.
Handle the Musical Chime carefully as you would any
precision instrument. Disconnect power to the existing door
c h i m e .
1. Remove the cover from the existing door chime.
2. Disconnect the wires from the terminal strip of the existing
door chime. Mark each wire as it is removed - front,
transformer and rear.

door) are present which are not required by the
wiring diagram, cap these wires individually with a
wire nut and electrical tape.
3. Remove the existing chime base from the wall.
4. Refer to Figure 2. Determine whether the Musical Chime
will be hung vertically or horizontally. Pull the remaining
wires through one of the large holes in the baseplate.

to the wall.
NOTE: If the Musical Chime is replacing a door chime
that was mounted horizontally, the two small round
holes in the base should align with the holes used to
mount the base of the old chime. If the Musical
Chime is replacing a door chime that was mounted
vertically, use the two slotted holes that have
T-shaped slots at the top.
6. Attach wires to the respective screw terminals (FRONT,
TRANS, REAR) that are located on the baseplate's
terminal block.
7. While holding the Musical Chime's housing in one hand,
attach the blue, yellow and green wires from the chime's
housing to the lugs marked FRONT, TRANS and REAR
respectively on the terminal block.
