Determine Chime Type
3. Locate your chime and remove the
cover. If you see tone bars and plungers
you have a mechanical chime (see
Figure 2). If not, you have an electronic
chime.
4. If you have a mechanical chime, go to
the Troubleshooting section, page 5. If
you have an electronic chime proceed
to step 5 on page 4.
CAUTION: Do NOT connect push-
button to mechanical chime if pushbut-
ton jumper is set for electronic chime
use. Doing so may result in permanent
damage to your chime.
