1. ON/STANDBY SWITCH
Press this button to switch “ON” the unit and press again to switch “OFF” unit into “STANDBY MODE”. If the unit is left
unattended for long periods, remove the AC cord from the power socket.
2. COLOR DIGITAL FLUORESCENT DISPLAY
The frequency of the station which has been in is indicated in digits. MHz units are used for FM frequencies and KHz units
for AM frequencies. When the MEMORY SCAN switch or the PRESET STATION switch is pressed, the current station
number will be displayed.
3. TUNING SWITCH (UPor DOWN)
Press UP or DOWN to search your favorite station.
Tuning can be performed either automatically or manually, depending on the setting of the tuning mode selector switch.
Auto tuning: When the DOWN TUNING switch is depressed, the frequency which is tuned in is counted down and this
countdown operation stops automatically as soon as the station is tuned in the LOCK indicator together with the relative
frequencies will be continuously counted down without stopping when stations are tuned in until you release the switch.
This will stop the automatic tuning operation when the lower frequency limit is reached, count-down changes over to
count-up.
Manual tuning: Every time one of the TUNING switches is depressed, the received frequency moves up or down in 50Khz
units for FM and 9 KHz for AM. (For USA, 10 KHz for AM). When the switches are kept in the depressed position, the
received frequency moves up and down rapidly in the units you release the switches.
* With manual tuning, the frequency will not stop changing as long as the UP or DOWN switch is held pressed.
4. FM STEREO/MONO SWITCH
This switch has a dual function:
It switches the stereo and mono reception. FM stereo broadcasts can be heard in stereo while FM mono broadcast are heard
in mono. Normally, the stereo is received when press the stereo/mono knob once. And the mono when the switch is pressed
once again, the relative light will be shown on the display. When received stereo signal is too weak, then there will be some
noise, you can press the mono key to cut the noise.
5. BAND SWITCH
Press this switch to select the broadcast band (AM or FM).
6. AUTO SEARCH SWITCH
This switch is used to select AUTO or MANUAL tuning of AM or FM stations. Press once to set to AUTO, press again to
set MANUAL.
7. MEMORY SWITCH
●Tune in the station you wish to preset.
Press the MEMORY switch. While this switch is held pressed, the MEMORY indicator will show.
Then press the PRESET STATION switch to enter the tuned station into the memory within 5 seconds.
8. PRESET STATION SWITCHES
Up to 9 AM or FM stations may be preset at random. Presetting the switches will allow you to tune in your favorite stations
simply and easily.
9. APS
Press this switch to allocate and memorize radio station automatically.
Note: Once you press this switch, the previous preset stations will disappear.

* Instructions and requirements indicated may vary to some extent depending on sales area, local law and regulations.
Connection precautions
* When connecting or re-locating the unit, be sure to turn the power off or disconnect the power cable.
* Check the left and right channels and align them correctly (L to left and R to right.)
Connections to amplifier
The supplied pin-plug cables should be used for connection between the unit’s rear panel OUTPUT terminals and your
amplifier’s TUNER terminals. Make sure not to confuse the left and right cables in connection.
FM antenna
Indoor T-shaped FM antenna
The T-shaped antenna included with the unit is meant for temporary use until an outdoor FM antenna is set up. Connect it to
the FM 300 Antenna terminals and open the arm ends to form a “T” shape. While listening to a broadcast, hold the stretched
ends and move around until it is facing in the direction in which the signals come in strongest, then attach to wall or ceiling.
FM antenna connection
Use the FM 300-ohms terminals when connecting the T-shaped FM feeder antenna supplied or a 300-ohms lead-in cable
from an outdoor antenna. Use the FM 75-ohms terminals when connecting a 75-ohms coaxial cable from an outdoor
antenna.
AM loop antenna connection
Connect the cord of the accessory AM loop antenna to the AM LOOP antenna terminals, and attach it to the accessory
antenna holder.
Attach antenna holder to a wall with the range of the loop antenna cord. When tuning into AM (MW, LW) stations, move
the antenna to the left or right and set it in the direction which yields the optimum reception.
* AM (MW, LW) reception is not possible with the loop antenna detached. Even if n outdoor AM antenna is erected, keep
this loop antenna in place.
* Do not bring the power cord or the speaker cords near the loop antenna since noise will be generated.
* Do not bring the loop antenna near the display, otherwise it will affect the reception.
