GB 9Connecting the Mediamaster & First-time installation• Some outdoor aerials are directed towards an analoguetransmitter. The aerial must be directed towards a digital TVtransmitter.• It is not always advisable to position the aerial as high aspossible. If problems arise, experiment with different aerialheights.2. Indoor and window-mounted aerialsThis type of aerial may be enough if the reception conditions arevery good. When an indoor aerial is used, please note the following:• Use an aerial for UHF/VHF channels (21-69), e.g. a directionalaerial.• Place the aerial by the window and direct it towards the TVtransmitter, if possible.• It is recommended that you use a Nokia active aerial with abuilt-in amplifier to provide a stronger signal.The strength of the TV signal varies according to reflections from,for example, buildings. The signal penetrates thick stone orconcrete walls poorly. A wooden building, however, is not aninsurmountable barrier for digital TV signals.The 5 V power for the active antennaThe Nokia active indoor antenna must be powered with 5 V fromthe TV aerial connector on the rear of the Mediamaster.If your Mediamaster is connected to a local antenna system, e.g. ina rented flat, the 5 V power might disturb the antenna system in thebuilding when it is switched ON. You can switch OFF the 5 V from theTV menu.First-time installation general informationOnce you have correctly connected the Mediamaster, you will alsohave to perform a "First-time installation." During this procedure,helpful information is displayed at the bottom of the menus.The ok button always confirms a selection within these menus,and pressing it will take you to the next step in the installationprocess. However, sometimes more than one value has to beentered in a menu. Make all the necessary changes first.Then, confirm them all simultaneously by pressing ok.• You can always go back to the previous menu by pressing back.• Use the cursor up/down buttons to move upwards anddownwards from one line to another.• Use the cursor left/right buttons to change settings.• Use the number buttons on the remote control to enter numericvalues.
