Installing Your Extension Miscellaneous Tips for Installing and Maintaining Your Extension Most often, your extension will be installed on your desk. Here are a few additional tips: • Never place your extension on fragile surfaces. To prevent it from scratching your desk, place an anti-skid mat underneath your extension. • Never place your telephone near any source of extreme heat, for example - next to a radiator. • Make sure that the line cable is never crimped. Use a soft, slightly damp (not wet) or anti-static cloth to clean your extension. Never use any abrasive solvents, liquids or cloths to clean your extension. Aastra cannot be held responsible for any damage to your telephone caused by any non-compliance with the above instructions. Installing Your Extension on a Wall Your extension may also be installed on a wall support, without any particular accessories. To do so, you must first rotate the hanging clip on the extension, thus ensuring that your extension's handset will be secure. It is made of flexible plastic. According to the instructions illustrated on the next page: • Begin by removing the hanging clip with a screwdriver. • Flip the clip over. • Re-insert it into your extension. 150 MD Evolution - Dialog 4223 Professional
