User's Manual

• Force a signal search on the device.
2. The gym equipment does not seem to work with your chest belt.
• Most gym equipment is compatible with analog transmission. This chest belt does
not transmit an analog signal, it only uses the low energy Bluetooth 4.0 technology.
3. Signal is jammed or there is interference from another person’s heart rate monitor:
• There is too much interference in the environment for your heart rate monitor to
function. Move to an area where the watch can register your heart rate reading
and/or force another signal search.
WARNING Signal interference in the environment can be caused by electromagnetic
disturbances. These may occur near high voltage power lines, traffic lights, overhead lines of
electric railways, electric bus lines or trams, televisions, car motors, bike computers, some motor
driven exercise equipment, cellular phones or when you walk through electric security gates.
Under interference, the heart rate reading may become unstable and inaccurate.

2. Use a coin to open the battery compartment lid by turning it anticlockwise to open.
3. Remove the old battery and insert a new CR2032, 3V lithium battery. Make sure to place
the battery in the compartment following the polarity +/-.
4. Secure the lid by turning the coin clockwise.
