Getting Started Connections Operation Troubleshooting Specifications NOTE • Use speakers with an impedance of 4 to 16 Ω/ohms. • When making connections, take care that none of the strands in the speaker cable come in contact with adjacent terminals, other speaker cable strands, or with the rear panel and screws. NEVER touch the speaker terminals when the power is on. Doing so can result in electric shocks. Protection circuit When using speakers with an impedance below the designated value (for example 3 Ω/ohms), playing for long periods of time with the volume high can cause the temperature to rise, activating the protection circuit. When this circuit is activated, the output to the speakers is cut off and the power indicator blinks. If this happens, unplug the power cord, wait for the set to cool off and improve ventilation around the unit. Also check the wiring of the input cables and the speaker cables. After doing this, plug the power cord back in and turn the unit's power back on. If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around the unit, switch off the power and contact a DENON service center. Connecting the antenna terminals An F-type FM antenna can be connected directly. Direction of broadcasting station FM outdoor antenna 75 Ω/ohms coaxial cable FM antenna (Supplied) Black White AM loop antenna (Supplied) AM loop antenna assembly Connect to the AM antenna terminals. ENGLISH Remove the vinyl tie and take out the connection line. a. With the antenna on top of any stable surface. Bend in the reverse direction. b. With the antenna attached to a wall. Mount Connection of AM antennas 1. Push the lever. 2. Insert the conductor. 3. Return the lever. Installation hole Mount on wall, etc. NOTE • Do not connect two FM antennas simultaneously. • Even if an AM outdoor antenna is used, do not disconnect the AM loop antenna. • It is not possible to receive AM broadcasts with good quality if the AM loop antenna is near something metallic. Note to CATV system installer: This reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC which provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
