How do I charge the battery in my Tacktick Race Master/Sail Master/Speed Master?
To achieve the best recharge time, you must place your instrument carefully with respect to the sunshine, making sure that the solar cell is perpendicular to the midday sun, and that the unit is placed outside. If you do not have a suitable outside location, then be sure that the indoor site chosen has DIRECT BRIGHT sunshine, for at least 10 hours of the day.Battery hours indicated at power up is affected by temperature! Ensure solar cell is at right angles to the midday sun. In the UK, for example, set the unit so the solar cell faces due south and is tilted upwards at 45 degrees Urgent charging for a weekend race Even in cloudy weather, if you position the solar cell as above for 5 days, then you should achieve enough charge to complete a weekends racing.
