3.2 IMPORTANT INFORMATION
Please consult your doctor before starting training – especially if you suffer
from any cardiovascular illnesses.
What happens if I remove the chest belt during training?
The watch will no longer receive any heart rate signal and “0” will appear on
the display. After a short time, the “0” will be replaced by the current time.
If a heart rate frequency is received again, it will automatically appear on
the display.
Does the SIGMA heart rate monitor completely switch off?
No. Only the time is displayed in sleep mode, so that you can also use the
heart rate monitor as a normal watch. The PC 3.11 uses very little power
in this state.
Can I use the chest belt on a treadmill?
Yes – the signals can be received and displayed by almost all
corresponding cardio devices.
Are SIGMA heart rate monitors waterproof and can they be used for
swimming?
Yes – the PC 3.11 is watertight up to 3 ATM (corresponds to a test
pressure of 3 bar). The PC 3.11 is suitable for swimming. Please note:
Do not press the buttons underwater, as otherwise water can enter
the housing. Avoid using in sea water, as malfunctions can occur.
