5OPERATING INSTRUCTIONS FOR THE NADY WA-120Powering the WA-120• External AdapterPlug the external provided AC/DC Adaptor into the External DC inputjack (14) socket. Then plug the AC/DC adapter plug into a standard115VAC or 240VAC outlet (The AC adapter will detect the line voltageautomatically). Turn on the unit using the Power switch (2).(Note: To avoid damaging your unit, use only the provided AC adapterconnected to the power input jack.)• RB-120The WA-120 can be powered internally using the optional RB-120 re-chargeable battery. Observe the RB-120 battery positive (+) and nega-tive (-) polarities when installing it into the Optional RB-120 recharge-able battery slot (11) while the WA-120 is connected to AC power withthe provided AC adapter. If the Battery charging LED (16) turns red,the RB-120 is not fully charged and should be allowed to charge whilethe WA-120 is powered by the AC adapter. (Note: Turning off the WA-120 Power switch (2) will allow the RB-120 to recharge more quickly.)If the Battery charging LED indicator (16) lights green, the RB-120 isfully charged and ready to power the WA-120 alone. Shut off the Powerswitch (2) and disconnect the AC adapter. Turn the unit back “ON” andthe RB-120 will power the unit while still connected to the optional RB-120 rechargeable compartment (11). The RB-120 can be easily stored inthe Storage compartment (11) while in use or transporting.(Note: Connecting the AC adapter will automatically charge the internalRB-120 battery power.)(Note: Connecting the AC adapter will automatically disconnect the inter-nal “D” cell batteries. The WA-120 does not recharge “D” cell batteries.)• (8x) “D” Cell BatteriesThe WA-120 can also be powered internally with (8x) ”D” cell batteries.Insert the batteries while observing the correct polarity as marked. Forlongest operation use only alkaline or rechargeable batteries. Replacethe batteries when the output volume drops or the range of the wirelessdecreases.(Note: The WA-120 does not recharge “D” cell batteries.)
