IntroductionA-01 Nav Master combines personal training and navigation functions into one compact wrist computer. It is among the world’s smallest of its kind and yet fully water resistance. It can withstand immersion in 30 meters of water. The GPS navigation function locates and tracks your position wherever you go. Nav Master is powered by a highly sensitive chip that tracks your position even at weak signal condition. It can be adopted for various kinds of outdoor activities such as Jogging, Running, Biking, Hiking, Skiing, Sailing, Hunting, etc. This package comes with a digitally coded Heart Rate Monitor (HRM) chest strap and a USB dedicated cable. The HRM listens to your physical condition and gives you warning instantly when you do exercise. This package comes with a dedicated USB cable. This USB clip cable is used for fast battery charging and data transfer between your Nav Master and PC in a snap. Data transfer is done by a PC software, GPS Master. It assists you with workout analysis, route planning and training summary reporting. It is a helpful partner that accompanies you to explore your physical limits and beyond. NAV Master A. Introduction: Warnings and Cautions Be sure that you fully understand the functions and limitations of this product before using it. The performance of this product, like most Global Positioning System equipment, depends on the satellites operated by the government of the United States. The satellite system may be subject to change which could affect the accuracy and performance of this product and all GPS equipment. This product is an assistant device for navigation. It is NOT a substitute for getting the navigating information from charts, maps, observations and experienced navigators. DO NOT use this product for navigation that requires precise navigation or is used for vital matters. This Watch and Chest Strap is a supplementary device for measuring heart rate; it is NOT a substitute for medical devices. You should periodically compare the heart rate readings acquired by this watch and Chest Strap with the readings from a doctor. Consult a doctor or trainer before setting your Upper and Lower heart rate limits. This product, like most electronic or magnetic devices, may interfere with the pacemaker. Therefore, it is safe for patients with pacemakers to check with their doctors before using this product. In case of doubt about the directions and positions of the way of navigation, consult the park administration office before starting the navigation. DO NOT expose your watch to extreme conditions. DO NOT use this Watch and Chest Strap for commercial or professional purposes. DO NOT charge or connect the unit with the USB clip when it is wet. Wipe dry and air dry before using. Although this unit is water resistance, you cannot wear it for swimming. The GPS and chest strap heart rate function do not work under water. CAUTION A-02 WARNING ! This product can only locate positions in an outdoor environment or open area. The more open the area is, the more accurate and faster information it can collect to locate the position. The first position can be located within 1 minute at cold start, and 10 seconds or at hot start. To use workout and navigation functions with GPS, turn on the GPS receiver and get the position updated in advance. Otherwise, the GPS related features are not working according to the current situation as the receiver collects satellite data constantly as long as the GPS of the watch is on. iThe Altitude is taken at the Mean Sea Level in meter/feet. iRinse and wash your Chest Strap with tap water and wipe it dry after each use. DO NOT take heart rate measurement when diving or under water. DO NOT use hand cream on the skin that is in contact with the sensor; it will insulate the transmission of the signals from the skin to the sensor.
