Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
– Avoid excessive heat, humidity, dust and vibration
Keep the unit away from locations where it is likely to be exposed to high
temperatures or humidity-such as near radiators, stoves, etc. Also avoid
locations which are subject to excessive dust accumulation, or to vibration
that could cause mechanical damage.
– Avoid physical shocks
Strong physical shocks to the unit may cause damage. Handle the unit with
care.
– Do not open the case or attempt repairs or modifications yourself
This product contains no user-serviceable parts. Refer all maintenance to
qualified service personnel.

FM ANTENNA TERMINALS The FM terminal accepts a 75 Ohm Coaxial cable that terminates at an FM antenna. Antenna position may affect performance so it may be necessary to reposition the antenna for the best reception. Note: The ability to receive an FM signal may be diminished by terrain, area buildings, and the construction materials of the building housing the receiver. Keep these circumstances in mind when selecting the type of FM antenna and its mounting position.
An indoor FM antenna is provided and should be suitable for most applications. Repositioning the antenna may be necessary to identify the optimum mounting location. If greater signal strength is required, replace the supplied antenna with a large outdoor FM antenna using 75 Ohm coax as the lead wire. -
