For the U.S.A., it is set to 1OkHz. Check that the switch is set properly before use. Set it to the 9kHz position when the channel allotment plan is changed and the intervals between the AM broad- casting stations change from 1OkHz to 9kHz units. NOTE: Contact your dealer and inquire if you are not sure about the c han nel al I otment pla n. LOADING THE BATTERIES Two size "AA" dry batteries are provided as accessories. They are used to retain the station presetting memory functions. Before using the unit, disconnect the power cord and load the batteries into the compartment on the rear panel as follows: 1. Slide the lid in the direction of the arrow and open the co mp a rt m ent (see Fig. 1). Load the batteries with the polarities properly aligned with the marks on the inside of the compartment (see F i s . 2 ) . Align the tab of the lid with the interlocking hole and depress the lid lightly. Battery Precautions: lf batteries are incorrectly used. they may leak or even break open inside the battery holder. Observe the following precautions when inserting and replacing the batteries. 1. Always be sure the + and - ends are aligned properly as shown above and as marked on the battery holder. 2. Do not use new batteries and partly used batteries at the same time. 3. Do not use different brands and types of batteries at the same time. niT-trn ".r.J L'orr. 10kHz position Fig.2 Insert tab into interlocking hole Fis. 3 F i s . 4 There are rechargeable dry cell batteries and non- rechargeable dry cell batteries. Always read the notes on the battery to be sure which kind you have. When replacing the batteries, always use the same type of batteries (carbon zinc) as the ones originally provided with the receiver. Do not use alkaline and nickel cad- mium type batteires. 2. 3. 4. 5. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 2. FRONT PANEL FACILITIES o powen swlrcH Power is supplied to the unit when this switch is depressed ("in" position). @ FM STEREo INDIcAToR This lights when receiving an FM stereo program. @ TU INDICATOR This lights when receiving the FM broadcasts. (This lights when depressed the FM switch). @ nru rNDrcAToR This lights when receiving the AM broadcasts. @ FREOUENcY scALE This scale is composed of 16light-emitting diodes (LEDs). During frequency scanning, the lighting moves from left to right or vice versa, depending on the direction corres- ponding to the TUNING SWITCH which has been de- pressed. @ rurueo rNDrcAToR This lights when the optimum tuning point has been located during reception. lt blinks when stations are being searched. @ TUNING switch This is used to tune in broadcasting stations. When de- pressed, the LEDs on the frequency scale light up in the leftward or rightward direction, depending on the direc- tion corresponding to the part of the TUNING switch which has been depressed. and frequency scanning starts. The TUNED indicator now starts to blink. When a station is located. the LEDs stop moving and the TUNED indicator lights up. The sound from the station can be heard in about 5 sec- onds. After that sound has been heard for these few sec- onds, the frequency scanning operation starts again. In this way, all the broadcasting stations are picked up in succession. NOTE: The sound of each station is heard for about 5 seconds but de- press the TUNING switch if this is not the required station or if you want to search the next station promptly. @ FM swrrcH Depress this switch for FM reception. @ nm swtrcH Depress this switch for AM reception. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 3.
