Built-In Range Extender Function
The series 9 range of doorbells have a built in range extender function,

The only condition will be to link the push button or buttons to all the chimes
that are required to be triggered by the range extender.

Maintenance

Your doorbell and push button require no maintenance except periodically
changing the batteries.
If using the correct batteries, battery life should be approximately:
• Up to 5 years for the doorbell; replace with 4 C alkaline batteries
• Up to 2 years for the push button; replace with a CR2032 lithium battery

Low Battery Notification

When the doorbell batteries are low, the bottom edge of the halo light flashes
yellow every 6 seconds until the batteries are replaced.
When the push button batteries are low, two beep sounds are heard after the
normal tune.
