The IP54 designation provides for limited dust and splash proofing of the radio per specified above. This
compatibility is factory guaranteed for a period of one year provided all the jack covers are securely in
place, any accessories connected must be specified genuine Alinco accessories and the radio has not
been disassembled by the customer. The factory has tested and made the equipment compatible to IP54
certi
fication during engineering. However, please understand that this equipment is NOT certified IP54
compliant but is designed to remain operational when used in hard conditions and is in no way stating
that you should attempt to wash the radio for cleaning. Warranty will not cover radios that are water/dust
damage due to negligence or misuse of the product.
The warranty period of dust and splash resistance is the same as the period of the product warranty.
■ Covering ranges
You may expect a range of approx.1.5km/1 miles or more when located on a flat, noise-free place like
on a beach.However,it may vary drastically depending on how to wear and carry the radios, surrounding
locations/conditions and static noise levels (below or near power transmission lines), etc. In urban areas
with many buildings or inside a building, such covering range will become drastically short even to
several tens of meters.
