SETTING USE THE AM CHANNEL STEP SWITCH (on the rear panel) Before the receiver leaves the manufacturing plant, this switch is set to the channel allotment plan of the destina- tion. 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 1 OkHz to 9kHz units. NOTE:Contact your dealer and inquire if you are not sure about the chan 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 oDen the compartment (see Fig. 1). 2. Load the batteries with the polarities properly aligned with the marks on the inside of the compartment (see Fis. 2). 3. 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. CHANNEL STEP f-Iil iTil ?? 9lHr J LtOrHz l OkHz position Fis.2 Insert tab into interlocking hole Fis. 3 Fis.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. 4. 5. 3
