DIP-switch setting, but make sure that the same setting is
selected on doorbell and doorbell push-buttons.
• Both doorbell push buttons can have their own melody setting. Set
the melody jumper [C] to the desired melody:
1 für Elise
• Close the DIP switch cover [4] of the doorbell. Secure the screw.
• Mount or place the doorbell push buttons in the desired locations
and close the doorbell push buttons. Protect them from harsh
weather conditions to prolong their life time. Make sure push
buttons are not surrounded by metal or near a strong magnetic
field.
• Mount or place the doorbell itself in the desired location (indoors
only). Make sure the doorbell is not surrounded by metal or near
a strong magnetic field.
• A push on the doorbell button will produce the chosen melody for
that button through the speaker [2] of the doorbell, while the
status LED [3] is lit.
7. Troubleshooting
• When sound becomes weak, replace the batteries of the doorbell
(see §8).
• When pushing a push button does not produce a chime:
• verify whether the DIP switch settings on doorbell and doorbell
push buttons are identical. Set the same setting on doorbell and
doorbell push buttons.
• verify whether the push button is located within the specified
range (max. 60m). If not, bring it closer to the doorbell.
• verify whether doorbell and doorbell push buttons are not
surrounded by metal or near a strong magnetic field. In these
cases, move the push button or doorbell to a suitable
location.
• replace the push button battery (see §8)
8. Batteries
