7 FAQ (FREQUENTLY ASKED QUESTIONS AND SERvICING)
What happens if I remove the chest belt during training?
The watch will no longer receive a signal. The screen will indicate “O”
and after a short period of time the PC 10.11 will go into sleep mode.
Does the SIGMA heart rate monitor completely switch off?
No – only the time and date are displayed in sleep mode, so that you can
also use the heart rate monitor as a normal watch. The PC 10.11 uses
very little power in this state.
The display responds sluggishly or shows a black coloration, what is
the reason for this?
The operating temperature may have been exceeded or fallen below.
Your heart rate monitor is designed for a temperature of 0°C to 55°C.
What should I do if the display is faint?
A faint display may be the result of a weak battery. The battery should be
replaced as soon as possible – battery type CR 2032 (ref. no. 00342).
Are SIGMA heart rate monitors waterproof and can they be used for
swimming?
Yes – the PC 10.11 is watertight up to 3 ATM (corresponds to a test
pressure of 3 bar). The PC 10.11 is suitable for swimming. Please note:
Do not press the buttons underwater as water can enter the housing.
Avoid using in sea water as malfunctions can occur.
