NOTE To switch from digital to
analog or analog to digital system,
press the chest belt button for
more than 4 seconds and then
force a signal search.
IMPORTANT If “HR ---“ is displayed because no signal
has been found, press and hold MODE/- to force a signal
search.
In the event that you experience a weak signal or your signal
is disrupted by interference in the environment, follow the
instructions below to identify and resolve the situation.
1. The signal is weak - the watch heart rate monitor will
only show “0”:
Shorten the distance between the heart rate chest
belt and watch.
Re-adjust the position of the heart rate chest belt.
Check the conductive pads are moist enough to
ensure solid contact.
Check the batteries. If they are low or exhausted,
the transmission range may be shortened.
Press and hold MODE/- to force a signal search.
2. The gym equipment does not seem to work with your
chest belt and the digital icon is displayed:
Most gym equipment is compatible with the analog
system . Press and hold the chest belt button
for more than 4 seconds to change from digital to
analog. Then press and hold MODE/- to force a
signal search.
3. Interference from another person’s heart rate monitor
- their heart rate readings appear on your watch, or the
heart rate monitor shows “0”:
Press the chest belt button to get the watch to
receive your chest belt signal. Do not press and
hold the chest belt button, as it will change the
transmission signal from digital to analog.
4. The signal is jammed - the heart rate reading on your
watch is flashing:
There is too much interference in the environment
for your heart rate monitor to function. Move to an
area where the heart rate reading stops flashing.
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.
NOTE If the watch is kept idle without receiving a heart rate
signal for half a minute, the heart rate mode will quit and
return to clock mode.
START EXERCISING
Before you start exercise, allow the watch a few seconds to
search for chest belt first. This is to ensure you can receive
comprehensive calculations (such as your lap, calorie and
heart rate) during exercise.
Ensure HR zone or limits have been set and if doing pre-
programmed exercise, that the time conditions have been set.
