1 INTRODUCTION AND PACKAGING CONTENTSCONTENTS

Congratulations on having chosen a bicycle computer from SIGMA SPORT

®

. Your new

BC 1909 HR will provide you reliable service in riding your bike for many years to come.

The BC 1909 HR is a state-of-the-art measuring instrument. Please read instructions
carefully to become familiar with the functions and usage of this bicycle computer.

SIGMA wishes you an enjoyable time using your BC 1909 HR.

The BC 1909 HR is fitted with an automatic Start/Stop. As soon as this is assembled
on the mounting bracket a movement sensor activates the BC 1909 HR at the smallest
movement of the bicycle or the hiking mounting. This automatically starts the connection.

kTo pair the speed, cadence and heart rate,
there are 2 options:

1. Ride, usually the receiver has paired with the transmitter
within 3 or 4 wheel turns.

2. Turn front wheel or pedals until the KMH /MPH or
cadence display stops flashing.

kWhile wearing the chest strap
either move close to the BC 1909 HR
or climb on the bicycle. As a rule,
the BC 1909 HR pairs with the
chest belt in less than 10 seconds.
