Frequently Asked Questions - PC 4 SIGMA

What happens if I remove the chest strap during exercise?

The watch no longer receives the signal and displays '0'. After a few moments, it goes into standby mode.

Does the heart rate monitor turn off completely?

No. In standby mode, only the time is displayed, allowing it to be used as a wristwatch with very low power consumption.

Can I use the chest strap on a treadmill?

Yes. The signals are received and displayed by most cardio training equipment.

Is the PC 4 waterproof? Can I swim with it?

Yes, up to a depth of 3 meters. Caution: do not press buttons underwater and avoid seawater.

Why is the display slow or showing a black tint?

This may be due to the operating temperature being exceeded (between 1°C and 55°C). Let the device return to a normal temperature.

What to do when the display is dim?

A dim display indicates a nearly empty battery. Replace it with a CR2032 battery (ref. 00342) at a specialist dealer.

How to set the time on the PC 4?

Press and hold the function button until 'hold' appears and the format flashes. Choose 12h or 24h, then set the hours and minutes by pressing the button repeatedly.

How to properly position the chest strap?

Place the transmitter at the base of the pectorals (men) or at the base of the breast (women). The SIGMA SPORT logo must be visible. Moisten the electrodes before use.

How to calculate my maximum heart rate?

Use the formula: for men: 210 - (age/2) - (0.11 x weight in kg) + 4; for women: 210 - (age/2) - (0.11 x weight in kg). A medical stress test is recommended.

What to do if no heart rate is displayed?

Check the strap positioning, electrode moisture, absence of electrical interference, and the condition of the transmitter battery (CR2032). Consult a doctor if the problem persists.

3.1 Useful facts about heart frequency 3.1 Useful facts about heart frequency

The heart rate frequency (HR) or pulse is recorded in beats per minute.

Maximum Heart Rate Frequency

The maximum heart rate (max HR) is the highest frequency possible, achieved at total exhaustion during physical performance. Some factors that can influence max HR are age, weight, sex, and fitness level. The best way to determine your max HR is a stress test.

We recommend that you have your doctor carry out this test for you at regular intervals.

The max. HR can also be estimated with the aid of a mathematical formula:

Men:

210 - "half age" - [0.11 x personal weight in kg] + 4

Women:

210 - "half age" - [0.11 x personal weight in kg]

[Note: To convert weight from lb. to kg, multiply by 2.2]

The correct training pulse

The training zone is the range in which the heart rate frequency should fluctuate during effective and targeted training. Three training zones can be classified from a sports medicine perspective:

Please be aware that these are general guidelines. Target zones will vary from person to person. Individualized training/personal goal setting is only possible through a well qualified trainer who knows the individual.

HZ (Health-Zone)

Health 55 - 70% of the HR max. Orientation: General wellness and weight reduction. This zone is commonly referred to the "fat burning zone. At this intensity, the body readily burns fat and carbohydrates for energy.

FZ (Fitness-Zone)

Fitness 70 - 80% of the HR max. Orientation: Advanced fitness, aerobic conditioning. Your training is considerably more intensive in the Fitness-Zone. Energy is primarily generated from the combustion of carbohydrates.

PZ (Power-Zone)

Performance 80 - 100% of HR max. Orientation: Competitive training. The training in the Power-Zone is very intensive and should only be performed by trained individuals.

3.2 Important information

If no heart rate frequency can be read on the display, this may be the result of the following:

The chest strap/transmitter is not worn properly
- The inside surfaces of the conductive ribbed rubber pads are not clean or not moist.
- Disturbance from electrical interference sources (high-voltage cables, railway lines etc)
- Transmitter battery (CR 2032) is empty (ref. no. 00342).
- In some cases, use of a conductive gel may be necessary.

Please consult your doctor before starting training - especially if you suffer from any cardiovascular illnesses.

3.3 Frequently asked questions and service 3.3 Frequently asked questions and service

What happens if I remove the chest belt during training?

The watch will no longer receive any signal, and "0" will appear on the display.

Does the SIGMA SPORT 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 wristwatch. The PC 4 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 SPORT heart rate monitors waterproof and can they be used for swimming?

Yes - up to a water depth of 3 meters.

Please note: Do not press the buttons underwater, as otherwise water can enter the housing.

Avoid using in sea water, as malfunctions can occur.

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 1^ to 55^ .

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)

Battery change.

A CR 2032 battery (ref. no. 00342) is used in the heart rate monitor und chest belt. The SIGMA SPORT heart rate monitor is a state-of-the-art measuring instrument. To ensure proper functioning and water tightness, the batteries should only be changed by an authorised dealer. Incorrect battery changes can damage the heart rate monitor leading to expiry of the claim to warranty.

After a battery change, the time has to be set again.
