TAHUNA TEASI ONE⁴text_image
Technical diagram of a device rear panel with numbered components for identificationThank you for choosing a product from TAHUNA. A very good choice! We hope you'll enjoy using your new Recreational Navigation System. Just in case that you are facing any problems with your device, visit http://tahuna.com/service
On our website – www.tahuna.com – you’ll find detailed manuals, updates and technical information.
Do you need additional accessory like charger, mount or a bag? Ask your dealer or simply visit our online shop at www.tahuna.com, for your order and more information.
The use and operation of navigation systems
Attention! Don't operate with the device while driving. Even the smallest and shortest distractions from road or traffic for you and other road users - even at slow speeds – may have devastating consequences.
Type in the destination before starting your journey and start the navigation system before you start driving.
If you have to change the route or the settings while driving, you should better stop for it.
After switching on the device it could take a few moments to find the required minimum number of navigation satellites. Depending on the environment, it may go faster or longer. Under the open sky, it is the fastest. In inner cities with narrow streets and tall buildings, this process may take longer, because the "view to the sky" is very narrow and that cause reflections of the satellite signals. In the forest it may also take longer because of the crowns of leaves. In tunnels, buildings, etc. the system does not work! As soon as you are positioned under the open sky the connections to the satellites will be established as quickly as possible.
The map data is up to date in time of production of your navigation system. Nevertheless, it may happen that you may have long-known streets, paths, house numbers, roundabouts, etc. are not included. This is not a fault, but due to the fact that streets are changing. Your device is using Open Street Map (OSM). This is in our opinion the most useful map for cyclists. OSM is a non-profit web-based collaborative project to create a free map of the world. We like this idea and we support it.
