1、STP-006 Will filter the input pulse if the frequency is over 4Hz
2、No doult pulse will transmit if the ECG signal is very weak
3、Have better performance subject to motion artifact during exercise
Good stability in low and high temperature
1、The carrier frequency is divided from 24M crystal， So it can keep at good frequency stability against temperature change
2、The frequency of the burst is 2.404GHz at -10°C to 60°C
3、The frequency of the burst is 2.404GHz at 2.4V to 3.6V
4、low power consumption。 The battery lifetime is up to 1 year @ 1hr per day
Congratulation for your purchase of this 2.4GHz Heart Rate Chest belt. This Chest belt is a high-technology wireless device employs 2.4GHz as the transmission media. It consists of ECG amplification circuit, low power microcontroller and 2.4GHz transmitter.
This chest belt picks up electrical signal caused by contraction of heart and transmits the RF signal (2.4GHz) to the watch.
??8??6Moisten the electrodes areas of chest belt under running water and make sure that they are well moistened.
??8??6Keep your unit clean. Clean it with mild soap and water solution. Dry it carefully with a soft towel. Never use alcohol or any abrasive material such as steel wool or cleaning chemical.
??8??6Store the chest belt unit in a cool and dry place. Do not store it in damp environment, in non-breathable material (such as plastic bag or sport bag), or with conductive material such as wet towel. Sweat and moisture can keep the transmitter electrodes wet and the transmitter activated, shortening battery life.
??8??6Do not blend and stretch the electrodes, this might damage the electrodes.
??8??6Person with pacemaker or another implanted electronic device is not recommended use this unit.
