INTRODUCTION
Congratulations on purchasing your CALL-HEAR
system. This consists of an Outdoor Unit(s) (ODU) and
an Indoor Unit(s) (IDU). The ODU is a large, clear,
weather resistant outdoor transmitter which can be
stuck onto an entrance door/glass/window not suitable
for iron doors. It is activated and will transmit a signal
via a bell push, a key or a combination of the two. The
person using this will be someone who requires
assistance and needs to alert someone of this. The IDU
receives the transmitted signal. The IDU will flash and
emit an alarm sound in order to alert someone to help
the person in need.
It is important that you read the instructions below in
order to use your CALL-HEAR system to its full
