About this appliance Those who want to live in a healthy manner should eat a balanced diet and exercise adequately. It is also advisable to continuously check your general health with a doctor. You can support this by measuring your pulse accurately yourself. After all the pulse is an excellent indicator of fitness. You can read your current pulse with the fitness watch. Therefore the fitness watch is the ideal companion for those who enjoy fitness, sportspeople etc. But please note the fitness watch is not a medical heart rate monitor! It i that can and must not replace a doctor! Only use it to aid daily fitness checking. For heart patients, those who are ill, older people or those starting to train: always consult your doctor before using the fitness watch!

When the watch is in the default screen it shows the time, date and day of the week. If a mode is no longer used the fitness watch returns to the default state after one minute. You can also return to the initial display at any time by holding down ESC for approx. 2 seconds. ESC: Hold down for 2 seconds to switch on background lighting. When in a menu press this button to leave the menu. ST./STP. Start/stop training/ time. Change value -, (vice versa). LP (LAP/RESET) Stop next lap. Change value +, (vice versa). E (ENTER): Open a menu. Change the settings in the menus. K1 und K2 The watch starts measuring the heart rate automatically when you press K1 with your index finger and K2 with your thumb at the same time. You can open this function at any time except during entry (display flashes) During the measuring process the heart symbol on the screen flashes. the start of heart rate measurement, there may be diffei At rent or fluctuating measurement values. Therefore only start training when the values displayed on the screen have normalised.
You can monitor training using the preset (FITNESS, FAT BURN or HEALTH. HLT) or individually set (USER) training range.

The healthier and fitter your heart, the quieter is its beat, even at rest. Why? Regular movement trains the heart. This increases its performance and it can move more blood with fewer beats. Therefore the resting pulse is an important indicator for physical fitness. Our tip: measure your resting pulse regularly, either just before sleeping or immediately after waking up. Certain heart illnesses result in a very slow pulse. i Caution: Before using your fitness watch it is essential for you to consult a doctor!
Training range Your heart beat should remain inside the training range throughout training. The heart rate training range is recommended at 50-75% of maximum heart range. This is calculated individually as follows: 220 minus age. An example: At an age of 32: 220-32=188. The ideal aerobic training range is between 94 and 141 (50% and 75%) beats per minute.

Notes on training
Training process
It is possible to measure the heart beat in each function except during entry (display flashes). The heart beat is measured from 40 to 200 bpm. If the heart beat measured exceeds 200 the screen no longer shows the heart beat. You can select an alarm tone that will sound when you exceed the upper or lower limit. During the measuring process the heart symbol on the screen flashes. Once the heart beat has been successfully measured a tone is emitted and the value is shown on the screen. The current heart beat is displayed on the screen for a further 5 seconds when you release the K2 button. If no signal is received for more than 5 seconds the screen displays the mode that is currently set.

Monitoring training
Measuring the heart beat
Pulse rate The pulse rate or “pulse frequency” describes the number of blood impulses leaving the heart. This is frequently measured by feeling any available artery (neck, groin, wrist). Heart rate The term “heart rate” describes the number of electrical excitations emitted by the heart. This can therefore be measured electrically, e.g. with an electrocardiogram (ECG). general the heart rate matches the pulse rate. With ceri In tain types of arrhythmia the pressure of the heart contractions may be too low and thus produce no measurable pulse rate.

Do not train for less than 20-30 minutes. However, it is basically true that if it is pleasant it is healthy. Do not overdo it!
