Receiver

Plug the receiver into the outlet. The receiver will
perform better if kept away from other electrical
equipment (eg TV, microwave etc.). Try and locate the
receiver in a clear line of sight to the bell push, if you are
experiencing signal problems try another location as
something could be interfering with it.

Transmitter

Clean the surface where you intend to mount the transmitter and the back of the transmitter.
Before mounting the transmitter, please run a test. Put receiver and transmitter where you
want to mount. Close all doors when you test. If the receiver does not sound, please see
Trouble Shooting section.

Mounting the transmitter with screws

1. Place the bell push mounting bracket on
the required location of the wall and
carefully secure with the fixing screws
provided.

2. Carefully push the bell push down onto
the mounting bracket until it locks into
place.

Mounting the transmitter with adhesive pad

1. Clean the area thoroughly before
trying to secure the bell push.

2. Stick the adhesive pad supplied
directly to the back of the bell push and
press it onto your required location. Do
not use the mounting bracket when
using the self-adhesive pad.
