7.2 Putting the ZF 460 chest band on (BB
3000, BB 3500, BB 4000)
A Attach the elastic band to the sensor. The
chest band can be adjusted to fit sizes M to
XXL.
B Moisten the inside of both contact points on
the right and left next to the sensor.
C Put the chest band on as illustrated.
The
TRELOCK logo on the transmitter must be
legible and must not be upside down!
Adjust the length of the elastic so that the
chest band fits comfortably, but cannot slip
during training.
Press the MODE button for 2 sec. and repeat
the procedure if necessary until the main menu
"Heart rate" appears on the display. If the chest
band has been put on correctly, the heart sym-
bol will now flash and the current heart rate will
be displayed – you can now start to train.
