Clock display - Press the CLOCK key for at least 2 seconds (until you hear a beep). - The display shows the time. After any tuning operations, the frequency will be displayed for about 10 seconds. Setting the clock - While the display shows the clock time, you can adjust time setting by pressing a 2-key combination as follow: CLOCK+ <C to adjust hours CLOCK+.. to adjust minutes To switch back to frequency display, press the CLOCK key for about 2 seconds (until you hear a beep). TRAFFIC ANNOUNCEMENTS ON FM You can switch on the TA mode to give priority to Traffic Announcements. Traffic Announcements can then interrupt cassette playback or mute. 2 Volume level for Traffic Announcements If you only want to hear Traffic Announcement. • Tune to your prefered TA-station. • Adjust the desired volume. • Briefly press 'MUTE '. Switch on TA mode (so that Traffic Announcements have priority) Select a FM band with BAND key. Press the TA key for at least 2 seconds (until you hear a beep). The display shows•~ TA' . If the tuned station does not enable the reception of Traffic Announcements.the display shows 'NO TA '. The radio automatically searches an appropriate station. You will hear the Traffic Announcements when broadcast. If you play a cassette, the radio will interrupt cassette playback each time a Traffic Announcement is broadcast. Interrupting a Traffic Announcement If you do not wish to continue listening to a particular Traffic Announcement, you car:i interrupt it without switching off the TA mode. • Briefly press the 'MUTE ' to silence the set or, • Press the TA key for at least 2 seconds (until you hear a beep).The set will return to its previous operating mode. Switching off TA mode (so that Traffic Announcements do not have priority) • Press the TA key for at least 2 seconds (until you hear a beep). TA disappears from the display. Note: - If the TA mode is switched on,search tuning only selects stations which enable the reception of Traffic Announcements. - If the tuned station b~comes too weak to enable the set to provide the RDS traffic service,you will hear beeps repeated at intervals.Use search tuning to find another station.
5 12v ~,--,, MOUNTING INSTRUCTION Voltage and polarity: The set must be connected to a 12V car battery with negative terminal to earth (car chassis). Warning: To prevent short-circuiting, disconnect the negative car battery terminal until the set has been mounted and connected. INSTALLING METAL SLEEVE • Install the metal sleeve in the dashboard (Fig.1 ). • Fix metal sleeve into place by pressing the metal tags outwards using a screwdriver (Fig.2). • If installing this set in a Japanese car, use the side holes which align with the holes in the side of the mounting opening (Fig.3). • Only use M5 screws that are not longer than 6mm. If necessary, remove the trim plate around the front panel and the side springs (Fig.3). POWER SUPPLV AND LOUDSPEAKER If your car is equipped with ISO connectors, simply insert them in connectors of the car radio. If not, you can use an adaptor cable (Refer to the table at the end of this booklet). Connection details Power supply Red lead: Connect to a switched 12V supply (switched on/off by car ignition). Yellow/red lead: Connect to a permanent 12V supply. This supply is needed for the set's memory. Grey lead: Connect to a 12V supply. When the car headlamps are switched on, the rotary knobs of radio are illuminated (even when the radio is switched off). Brown lead: Connect to earth (car chassis). • 2-1 i;,-~,;; ""7 '? .

MOUNTING RADIO (Figs.4) • Insert aerial plug into aerial socket (good reception is only possible with a good aerial). Slide the radio into the metal sleeve until the springs at either side of the radio snap into the openings of the sleeve . • Finally reconnect the negative car battery terminal. REMOVING RADIO (using the two U- brackets supplied) • Insert both U-brackets@ into the holes® until they lock. Pull out the radio (Fig.5). REPLACING FUSE Use a 3A blade-type fuse (Fig.6). PCS 77 749
