   • A 25.5” telescopic whip antenna for SW/FM/AIR
   • A 3.5mm jack to connect an external antenna of your choice for SW/FM/AIR
   Caution: Ensure that an external antenna is clearfrom power lines.
   The internal ferrite bar antenna is directional. Physically turn the radio for
   best reception. You may find that moving the radio to a different location,
   even slightly, greatly improves reception on all bands.

Radio operation

1. Search Radio Frequency
   ① Manual Search
   Turn the [Tuning] knob to change the frequency, Turn the [ Fine Tuning ] thumb
   wheel to fine-tune the frequency in smaller steps, or press the [ Up or Down
   Tuning Arrow ] to change the frequency.
   Note: Tuning speed
   The tuning knob has FAST, SLOW and STOP modes. Switch between them by pressing
   the [ Tuning ] knob in towards the radio. The display shows the mode in small
   print.
   • Fast – advance 5 kHz (3 kHz on LW, 9/10 kHz on MW, 25kH on AIR and 100 kHz
   on FM)
   • Slow – advance 1 kHz (10 kHz on FM)
   • Stop – does not advance
   ② Auto Search
   · ATSFunction
   Avoid areas with high electromagnetic interference when using the ATS function
   to obtain more accurate search results. Noise, such as from desktop computers
   can be confused with a radio station.
   Long press a band button ([FM], [LW/MW], [SW], [AIR]) and the screen displays
   “ATS _” to enter the automatic search mode. In this mode, the radio will
   automatically search all frequencies in the band and store all strong signals
   in the memory station.
   ( Note: strong signals are not necessarily generated by broadcast towers,
   they may also be strong interference signals. )
   ·UpandDownTuningArrow
   To search the frequency band starting with the current frequency:
   Select the desired frequency band, then long press the [Up or Down Tuning
   Arrow], the radio will start searching the selected frequency band, forward or
   backward, and stop searching after locating for a strong signal. Short
   pressing the [UporDown Tuning Arrow] will also stop the search.
   ( Note: Stations found in this search are not stored in the station
   memory. )
   ③ Directly input the radio frequency
   Press [FREQ] button to enter the keyboard input radio mode, enter the radio
   station you want to search through the numeric keypad, and press [FREQ] button
   again to confirm. The frequency band will jump to the frequency band you
   entered.
   ( Note: If the entered radio frequency does not exist in this band, the screen
   will display an Error symbol. )

2. Memory System
   ·Manual
   A memory location stores the station frequency along with the stereo setting
   for FM and the bandwidth for LW/MW/SW.
   This radio has 500 memory locations, 100 for each band, organized into 10
   pages with 10 memory locations each. Therefore, the storage location of each
   radio station is “page (0-9) -code number (0-9)”, for example “P18” refers to
   the 8th slot on page 1.
   Select the desired band (FM, MW, LW, SW or AIR) first. Then to save or
   retrieve a station in memory, first establish the current memory page by
   pressing the [PAGE] button and then pressing the page number button (0-9).
   Once a page is selected, a frequency is stored to a memory location within the
   page by long pressing the position number button (0-9). After the station is
   successfully saved, the radio will display “PAGE—SAVE”.
   ( NOTE: To recall a saved station, just press the number button (0-9) of
   the memory position within the current page. After the station is successfully
   retrieved, the radio will display “ PAGE— LOAD”. )
   ·Auto Tune Storage (ATS)
   This radio has the capability to scan the bands and automatically store
   stations into memory. It loads them sequentially by page, and by position
   within the page, overwriting any previously stored stations. ATS is invoked by
   first selecting the band and then with a long press of the band button, FM,
   LW, MW, SW or AIR. ATS stores relatively stronger stations, and may skip some
   that are barely audible.
   Note that for shortwave, the radio only scans within the international
   broadcast frequencies, not amateur radio or commercial bands. Refer to the SW
   topic.

3. Bandwidth (BW)
   While radio signals are centered on one frequency, they actually occupy a
   range of frequencies.
   Sometimes two stations with adjacent frequencies can interfere with each
   other. This problem can be lessened by reducing the frequency range
   (bandwidth) the radio tunes. This feature is available on LW, MW and SW on
   this radio, but typically only used on SW.
   The bandwidth is selected by pressing the [ AM BW ] button. The width is shown
   on the display ,and repeated presses of the button will cycle through the
   values: 6, 4, 3, 2.5, 2, 1.8 and 1 kHz .The bandwidths in SSB mode are 4, 2,
   2.2, 1.2, 1, and 0.5 kHz.
   Generally, the higher the bandwidth, the better the audio fidelity and the
   lower the bandwidth, the lower the interference and noise.

4. Squelch Function
   Press the [ Tuning ] knob for about 5 seconds, squelch mode will start.
   Squelch Mode works on all bands.
   When set, the radio remains silent until a transmission stronger than the set
   level is received. To activate the feature, long press the tuning knob
   inwards, and when the word “Squelch” appears in the display immediately rotate
   the tuning knob to begin setting the squelch level. The values are 1-9 and
   OFF. The higher the number, the stronger the signal must be to activate the
   radio. The optimum level is usually the highest number without background
   noise. Turning squelch off may enable reception of weak signals that would
   otherwise not be heard.
   ( Note: If you find your radio not receiving any signals, check to make
   sure the squelch is not turned on unintentionally. )

5. Display Mode
   The display can be set to show different information; press the [ DISPLAY ]
   button to cycle between signal strength/signal to noise ratio, time,
   temperature and alarm time. Signal strength is expressed in dBu units, the
   larger the number, the stronger the signal. The signal to noise radio is
   expressed in dB units; the larger the number, the greater the signal quality,
   with a value of 0 indicating that signal and noise are equal. The value is
   also shown as 0 when there is no signal at all.

6. FM Reception
   To receive FM broadcasts, fully extend the whip antenna and press the [ FM ]
   button.
   Here are your tuning options:
   1. Press [FREQ] button, enter the frequency of the station, and press [FREQ]
   button again.
   2. Long press the [FM] button to activate ATS to store all strong stations
   into memory (see section on the Memory system for how to access them).
   3. Press the [Up or down arrow] keys to go to the next frequency.
   4. Long press the [Up or down arrow] to scan for the next strong station.
   5. Rotate the tuning knob to tune stations.
   FM STEREO
   Some FM stations broadcast in stereo. In this case, STEREO appears on the
   display. Listening to the two stereo channels requires stereo headphones.
   Stereo can be turned off and on with the [FM ST] button. It may be
   automatically disabled for a weak signal. In some situations, you may get
   improved reception by turning stereo off. The stereo setting is stored in the
   station memory when the frequency is saved.

7. FM RDS (radio data system)
   RDS is a means for FM radio stations to transmit data along with their
   programming. Not all FM stations employ RDS, but the ones that do typically
   transmit the station name, the station type, the song artist and title when
   playing music, and occasionally the time. When RDS is present, the RDS icon on
   the display is shown and the RDS data information appears at the bottom of the
   display. Use the [INFO] button to cycle through the RDS data options. This
   radio supports the following RDS information:
   • PS-Program Service Name
   • DATE-Date and Time (“NO DATE” if not present)
   • PTY-Program type: News, Drama, Rock music… (“NONE” if not present)
   • RT- Radio Text may contain artist and title information for music (“NO RT”
   if not present)
   RDS date information can be used to automatically set the radio clock. Refer
   to the Clock Setting topic for additional information.
