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 latter 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 15.11 is watertight up to 3 ATM (corresponds to a test
pressure of 3 bar). The PC 15.11 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.
