Using the EnGenius DuraFon PRO Base Unit is easy. First, connect it to an analog port of your PBX, phone system, or analog phone line. You can then pair it with compatible handsets like DuraWalkie handsets. For the 2 - way broadcast feature, you can use either the analog port/line or directly from another PRO or DuraWalkie handset. When setting up multiple base units, ensure they are properly configured for the multi - base system. Note that the base unit doesn't come with handsets, so you'll need to purchase them separately. For best performance, use the optional external antenna in large warehouses, manufacturing plants, farms, or car lots. To maintain your base unit, keep it in a dry and clean place. Regularly check the connections to make sure they are secure. If you experience any issues, consult the user manual or contact EnGenius customer support.
