WATCH 
You can wear the receiver watch on your wrist or strap it to 
a bike or exercise machine, as shown below. 
TRANSMISSION SIGNAL 
The heart rate chest belt and watch have a maximum 
transmission range of about 62.5 centimetres (25 inches). 
They are equipped with the latest digital coding system to 
reduce signal interference from the environment, as well 
as analog technology. For more accurate readings use the 
digital transmission signal. You should only switch to the 
analog transmission signal if the situation in point 2 occurs 
(see below). Your watch will advise you which system it 
is using and the signal status by displaying the following 
icons: 
 NOTE  Whenever the watch is searching for the chest 
belt signal (manual or automatic search), make sure that 
the chest belt is no further than 10 cm (4 inches) from the 
watch.

 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 the heart icon does not appear on the 
display or is not flashing because no signal has been found, 
force a signal search. See “Signal Search” section on how 
to do this. 
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.
