2. Press MO (monaural), while still in the functions mode, so that the MO indicator lights up on the display.
   Each time you press the button, the MO indicator lights up and goes off alternately.When the MO indicator is lit on the display, the sound you hear becomes monaural but the reception will be improved.

Storing stations in memory
You can use one of the following two methods to store broadcasting stations in memory.

• Automatic preset of FM stations: SSM (Strongstation Sequential Memory)
• Manual preset of both FM and AM stations

FM station automatic preset: SSM
You can preset 6 local FM stations in each FM band (FM1, FM2, and FM3).

1. Select the FM band (FM1 – 3) you want to store FM stations into.
2. Press and hold both buttons for more than 2 seconds.

Local FM stations with the strongest signals are searched and stored automatically in the band number you have selected (FM1, FM2, or FM3).
These stations are preset in the number buttons—No.1 (lowest frequency) to No.6 (highest frequency).
When automatic preset is over, the station stored in number button 1 will be automatically tuned in.

Manual preset
You can preset up to 6 stations in each band (FM1, FM2, FM3, and AM) manually.
Ex.: Storing FM station of 88.3 MHz into the preset number 1 of the FM1 band.

1. Select the band (FM1 – 3, AM) you want to store stations into (in this example, FM1).
2. Tune in to a station (in this exampleof 88.3 MHz).
3. Press and hold the number button (in this example, 1) for more than 2 seconds.
4. Repeat the above procedure to store other stations into other preset numbers.

Notes:

• A previously preset station is erased when a new station is stored in the same preset number.
• Preset stations are erased when the power supply to the memory circuit is interrupted (for example, during battery replacement). If this occurs, preset the stations again.

Tuning in to a preset station
You can easily tune in to a preset station. Remember that you must store stations first. If you have not stored them yet, see “Storing stations in memory” on pages 8 and 9.

1. Select the band (FM1 – 3, AM).
2. Select the number (1 – 6) for the preset station you want.

RDS OPERATIONS

What you can do with RDS
RDS (Radio Data System) allows FM stations to send an additional signal along with their regular programme signals. For example, the stations send their station names, as well as information about what type of programme they broadcast, such as sports or  music, etc. Another advantage of RDS function is called “Enhanced Other Networks.” By using the Enhanced Other Networks data sent from a station, you can tune in to a different station of a different network broadcasting your favorite programme or traffic announcement while listening to another programme or to another source such as CD.
By receiving the RDS data, this unit can do the following:

• Tracing the same programme automatically (Network-Tracking Reception)
• Standby Reception of TA (Traffic Announcement) or your favorite programme
• PTY (Programme Type) search
• Programme search
• And some other functions

Tracing the same programme automatically (Network-Tracking Reception)
When driving in an area where FM reception is not good, the tuner built in this unit automatically tunes in to another RDS station, broadcasting the same programme with stronger signals. So, you can continue to listen to the same programme in its finest  reception, no matter where you drive. (See the illustration on page 16.)
Two types of the RDS data are used to make Network-Tracking Reception work correctly—PI (Programme Identification) and AF (Alternative Frequency).
Without receiving these data correctly from the RDS station you are listening to, NetworkTracking Reception will not operate.

To use Network-Tracking Reception
You can select the different modes of networktracking reception to continue listening to the same programme in its finest reception.
When shipped from the factory, “AF” is selected.

• AF: Network-Tracking Reception is activated with Regionalization set to “off.”
  With this setting, the unit switches to another station within the same network when the receiving signals from the current station become weak. (In this mode, the programme may differ from the one currently received.)
  The AF indicator lights up but the REG indicator does not.

• AF REG: Network-Tracking Reception is activated with Regionalization set to “on.”
  With this setting, the unit switches to another station, within the same network, broadcasting the same programme when the receiving signals from the current station become weak.
  Both the AF indicator and the REG indicators light up.

• OFF: Network-Tracking Reception is deactivated.
  Neither the AF indicator nor the REG indicator lights up.

1. Press and hold SEL (select) for more than 2 seconds so that one of the PSM items appears on the display.
   (PSM: see page 23.)

2. Select “AF-REG” (alternative frequency/regionalization reception) if not shown on the display.

3. Select the desired mode—“AF,” “AF REG,” or “OFF.”

4. Finish the setting.

Using TA Standby Reception
TA Standby Reception allows the unit to switch temporarily to Traffic Announcement (TA) from the current source (another FM station or CD).

• TA Standby Reception will not work if you are listening to an AM station.

Press TP/PTY to activate TA Standby Reception.

When the current source is FM, the TP indicator either lights up or flashes.

• If the TP indicator lights up, TA Standby Reception is activated.
  If a station starts broadcasting a traffic  announcement, “TRAFFIC” appears on the display, and this unit automatically tunes in tothe station. The volume changes to the preset TA volume level (see page 15) and the traffic announcement can be heard.

• If the TP indicator flashes, TA Standby Reception is not yet activated since the station being received does not provide the signals used for TA Standby Reception. To activate TA Standby Reception, you need to tune in to another station providing these signals.
  Press to search for such a station.
  When a station providing these signals is tuned in, the TP indicator stops flashing and remains lit. Now TA Standby Reception is activated.

When the current source is other than FM,
the TP indicator lights up.
If a station starts broadcasting a traffic announcement, “TRAFFIC” appears on the display, and this unit automatically changes the source and tunes in to the station.
To deactivate the TA Standby Reception, press TP/PTY again.
Using PTY Standby Reception
PTY Standby Reception allows the unit to switch temporarily to your favorite programme (PTY:
Programme Type) from the current source (another FM station or CD).

• PTY Standby Reception will not work if you are listening to an AM station.
  You can select your favorite programme type for PTY Standby Reception.
  When shipped from the factory, PTY Standby Reception is turned off. (“OFF” is selected for PTY Standby Reception.)

1. Press and hold SEL (select) for more than 2 seconds so that one of the PSM items appears on the display.
   (PSM: see page 23.)

2. Select “PTY STBY” (standby) if not shown on the display.

3. Select one of the twenty-nine PTY codes. (See page 16.)
   Selected code name appears on the display and is stored into memory.

4. Finish the setting.

Searching your favorite programme

You can search any one of the PTY codes. In addition, you can store your 6 favorite programme types in the number buttons.
When shipped from the factory, the following 6 programme types have been stored in the number buttons (1 to 6).
To store your favorite programme types, see below.
To search your favorite programme type, see page 14.

To store your favorite programme types

1. Press and hold TP/PTY for more than 2 seconds while listening to an FM station.
2. Select one of the twenty-nine PTY codes. (See page 16.)
3. Press and hold the number button for more than 2 seconds to store the PTY code selected into the preset number you want.“MEMORY” and the selected code name alternate on the display.
4. Press and hold TP/PTY for more than 2 seconds to exit from this mode.

To search your favorite programme type

1. Press and hold TP/PTY for more than 2 seconds while listening to an FM station.
2. To select one of your favorite programme typeor To select any one of the twenty-nine PTY-codes3 Press to start PTY search for your favorite programme.

• If there is a station broadcasting a programme of the same PTY code as you selected, that station is tuned in.
• If there is no station broadcasting a programme of the same PTY code as you selected, the station will not change.

Note:
In some areas, the PTY search will not work correctly.

• After starting the heater in the car.
• If it becomes very humid inside the car. Should this occur, the CD player may malfunction. In this case, eject the CD and leave the unit turned on for a few hours until the moisture evaporates.

When playing a CD-R or CD-RW
Before playing back CD-Rs or CD-RWs, read their instructions or cautions carefully.

• Use only “finalized” CD-Rs or CD-RWs.

• Some CD-Rs or CD-RWs may not play back on this unit because of their disc characteristics, and for the following reasons:
  – Discs are dirty or scratched.
  – Moisture condensation on the lens inside the unit.
  – The pickup lens inside the unit is dirty.

• CD-RWs may require a longer readout time since the reflectance of CD-RWs is lower than that of regular CDs.

• CD-Rs or CD-RWs are susceptible to high temperatures or high humidity, so do not leave them inside your car.

• Do not use following CD-Rs or CD-RWs:
  – Discs with stickers, labels, or protective seal stuck to the surface.
  – Discs on which labels can be directly printed by an ink jet printer.
  Using these discs under high temperatures or high humidity may cause malfunctions or damage to discs. For example,
  – Stickers or labels may shrink and warp a disc.
  – Stickers or labels may peel off so discs cannot be ejected.
  – Print on discs may get sticky.
  Read instructions or cautions about labels and printable discs carefully.

CAUTIONS:

• Do not insert 8 cm CDs (single CDs) into the loading slot. (Such CDs cannot be ejected.)
• Do not insert any CD of unusual shape—like a heart or flower; otherwise, it will cause a malfunction.
• Do not expose CDs to direct sunlight or any heat source or place them in a place subject to high temperature and humidity. Do not leave them in a car.
• Do not use any solvent (for example, conventional record cleaner, spray, thinner, benzine, etc.) to clean CDs.
