Be sure to keep the Operating Instructions for future reference. All warnings and cautions in the Operating Instructions and on the unit should be strictly followed, as well as the safety suggestions below. Installation 1 Water and moisture -- Do not use this unit near water, such "CAUTION:TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL." as near a bathtub, washbowl, swimming pool, or the like. 2 Heat -- Do not use this unit near heat sources, including heating vents, stoves, or other appliances that generate heat. It also should not be placed in temperatures less than 5°C (41"F) or higher than 35°C (95"F). 3 Mounting surface -- Place the unit on a flat, even surface. 4 Ventilation -- The unit should be situated with adequate space around it so that proper heat ventilation is assured. Allow 10 cm (4 in.) clearance from the rear and the top of the unit, and 5 cm (2 in.) from each side. - Do not place the unit on a bed, rug, or similar surface that may block the ventilation openings. - Do not install the unit in a bookcase, cabinet, or airtight rack where ventilation may be impeded. 5 Objects and liquid entry --Take care that objects or liquids do not get inside the unit through the ventilation openings. 6 Carts and stands -- When placed or mounted on a stand or cart, the unit should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the unit or m A~- 3 cart to overturn or fall. 7 Wall or ceiling mounting --The unit should not be mounted on a wall or ceiling, unless specified in the Operating Instructions. Electric Power 1 Power sources -- Connect this unit only to power sources specified in the Operating Instructions, and as marked on the unit. Polarization -- As a safety feature, some units are equipped with polarized AC power plugs which can only be inserted one way into a power outlet. If it is difficult or impossible to insert the AC power plug into an outlet, turn the plug over and try again. If it is not still inserted easily into the outlet, please call a qualified service technician to service or replace the outlet. To avoid defeating the safety feature of the polarized plug, do not force it into a power outlet. AC power cord - When disconnecting the AC power cord, pull it out by the AC power plug. Do not pull the cord itself. - Never handle the AC power plug with wet hands, as this could result in fire or shock. - Power cords should be firmly secured to avoid being severely bent, pinched, or walked upon. Pay particular attention to the cord from the unit to the power socket. - Avoid overloading AC power plugs and extension cords beyond their capacity, as this could result in fire or shock. Extension cord -- To help prevent electric shock, do not use a polarized AC power plug with an extension cord, receptacle, or other outlet unless the polarized plug can be completely inserted to prevent exposure of the blades of the plug. When not in use -- Unplug the AC power cord from the AC power outlet if the unit will not be used for several months or more. When the cord is plugged in, a small amount of current continues to flow to the unit, even when the power is turned off. 2 3 4 Owner's record For your convenience, record the model number and serial number (you will find them on the rear of your unit) in the space provided below. Please refer to them when you contact your Aiwa dealer in case of difficulty. Model No. AV-D25 I ENGLISH 5 Serial No. (Lot No.) Outdoor Antenna 1 Power lines -- When connecting an outdoor antenna, make sure it is located away from power lines. 2 Outdoor antenna grounding -- Be sure the antenna system is properly grounded to provide protection against unexpected voltage surges or static electricity build-up. Article 810 of the National Electrical Code, ANS1/NFPA70, provides information on proper grounding of the mast, supporting structure, and the lead-in wire to the antenna discharge unit, as well as the size of the grounding unit, connection to grounding terminals, and requirements for grounding terminals themselves.

Check that the rated voltage matches your local voltage. IMPORTANT Connect the speakers, antennas, and all other external equipment first. Then connect the AC cord at the end. CONNECTING EQUIPMENT Jacks and plugs of the connecting cord are color-coded as follows: Red jacks and plugs : For the right channel of audio signals White jacks and plugs: For the left channel of audio signals Yellow jacks and plugs: For video signals Insert the plugs fully into the jacks. Loose connections produce a humming sound or other noise interference. may *I Be sure to connect the VIDEO OUT terminal of a DVD player directly to aTV set, not through this unit. Otherwise, the picture noise may appear when playing the DVDS copy protected. *2 Input sound through the 5.1 INPUT terminals cannot be recorded. When recording the sound from the DVD player, connect the AUDIO OUT (DOWN MIXING) terminals of the DVD player to the VIDEO l/DVD/MD AUDIO IN terminals of the unit. *3When connecting a monaural video, use a sterao-mono connecting cord (not supplied).

Connecting + to +, ­ to - terminals To get the proper sound effect, the speaker terminals on the unit and the speaker should be connected with proper polarity; the+ terminal on the unit should be connected to the + terminal on the speaker (and - to ­). Lift up the terminal flap, insert the speaker cord lead into the terminal slot, then close the flap. Check that the cord is connected securely. Surround speakers q m Be sure to connect the speaker cords correctly as shown in the illustration on the right column.

FM antenna >Y Position the speakers to make the most of the Dolby Digital Surround (5. 1 CH), Dolby Pro Logic or DSP effect. @ Front speakers @ Center speaker Position in the center of the two front speakers. In addition, position on or below the TV set, if connecting a TV set to the unit. @ Surround speakers Place the surround speakers directly to the side of or slightly behind the listening area. Align them horizontally, about 1 meter (3.2 feet) above ear height. @ Sub woofer Place the sub woofer in any place between the two front speakers. , Sound from the surround speakers or center speaker depends on the setting of the DSP, Dolby Pro Logic and 5.1 CH function. To stand the AM loop antenna on a surface Fix the claw to the slot as shown in the illustration. To position the antennas FM feeder antenna: Extend this antenna horizontally in a T shape and fix its ends to the wall. AM loop antenna: Position for the best reception. m q q q Do not bring the FM antenna near metal objects or curtain rails. Do not bring the AM antenna near other external equipment, the unit itself, the AC power cord or speaker cords, as noise will be picked up. Do not unwind the AM loop antenna wire. CONNECTING AN OUTDOOR ANTENNA For better FM reception, use of an outdoor antenna is recommended. Connect the outdoor antenna to the FM 75 Q terminals. 5 ENGLISH ABOUTTHEREMOTE CONTROL BEFORE OPERATION POWER II TAPE MONITOR Function indicators VOLUME I Inserting batteries Detach the battery cover on the rear of the remote control and insert two R6 (size AA) batteries.
