20、y with CHA OFF showing up & Ni-MH Battery disappearing to activate the consumption display of regular batteries and turn off the built-in charging system. Using Rechargeable Batteries for power supply: Turn off the radio, press & hold the BATTERY key with CHA ON and Ni-MH Battery showing up to activ

21、ate the consumption display of rechargeable batteries and turn on the built-in charging function. . - 26 - SYSTEM SETTING (In Power Off Mode) Note:This radio is default to use rechargeable batteries for power supply. In case of using regular batteries, you should switch the radio system to regular b

22、atteries mode in order to show the correct power capacity. RESET PROCEDURE If the radio does not function properly, you can perform a reset by using a pointed object such as straightened paper clip, into the RESET hole in the bottom of the unit, and gently press and release. Note: Station memory wil

23、l not be removed after you push the reset button. IMPORTANT MATTERS FOR USING BATTERIES 1.The Clock memory will be gone if the unit has no power supplied by either batteries or adaptor for a long time, but the pre-stored frequencies will still be kept. 2.When the battery power is low, the symbol in

24、the display will flash to alert you for changing new batteries. And it will turns off automatically when the power is gone. 3.Mix using the used & new batteries would cause damage of radio and incorrect display of power capacity. 4.In order to avoid leakage, always remove the batteries when the unit

25、 will not be used for a long period of time. - 27 -. TROUBLE SHOOTING QUESTIONSANSWERSSOLUTIONS - Batteries have no power- Replace all batteries with new one. - Installing batteries incorrectly - Observing the polarities of battery, then re-install all batteries again. Can not turn on the radio. - K

26、ey knob function is being activated. - Press the button to deactivated it. - Batteries have no power- Replace all batteries.Radio turn off while listening.- Sleep timer is being activated. - Turn on the radio again. During ATS, some station cannot be stored. - Frequency of stations are too weak. - S

27、earch the station manually Some stored station with noise. - There is interference near by your area. - Low down the antenna or move to other location and try again. Only limited FM stations can be received. - FM frequency might be set as 7690 MHz accidentally. - Turn off the radio, press & hold the

28、 FM SET button to select the accurate FM frequency range. Poor AM reception in USA. - USA is using 10 kHz AM tuning step not 9 kHz. - Turn off the radio press the 9/10kHz button to select accurate tuning step. The sound of SW SSB broadcasting is too low. The default bandwidth is Narrow band. Press t

29、he AM BW button to select the Wide band. - Did not set the proper radio station for the alarm. - Preset your alarm station properly When the alarm is on, there is only noise with the broadcast.- Or there is no broadcasting at that radio station. - Or you are in another city where does not have a rad

30、io station for your preset frequency. - Make sure it has radio broadcast in your location. . - 28 - TROUBLE SHOOTING QUESTIONSANSWERSSOLUTIONS The charging time becomes shorter and shorter. The chargeable batteries getting old. Replace the old rechargeable batteries with new ones. Radio malfunction.

31、This may caused by interference, and the computer microchip does not function properly. Remove all batteries, then reload again. If it is still not working, please press on the reset button with a pointed object. - 29 -. SPECIFICATIONS 1.Frequency Range: FM: 76 108 / 87 108 MHz Step: 0.01 MHz / 0.1
