[. . . ] E two supplied keys release tabs inside the unit’s sleeve so you can remove it. Insert the keys as far asthey will go (with the notches facing up) into the appropriate slots at the middle left and right sides of the unit. Unt the sleeve by inserting the sleeve into the opening of the dashboard and bend open the tabs located around the sleeve with a 17 INSTALLATION screwdriver. Not all tabs will be able to make contact, so examine which ones will be most effective. [. . . ] tA SEEK or ALARM→PI SOUND or MUTE→ RETUNE L or S→ MASK DPI or ALL→ BEEP 2’nd，ALL or OFF a). SEEK OR TA ALARM - TA SEEK mode: When newly tuned station does not receive TP information for several seconds, the radio retunes to next station which has not the same station (PI) as the last station, but has the TP information. When TP information gets lost at the current station for retune time which is set by RETUNE SHORT (30 sec. When same PI station does not catch in 1 cyclic search, the radio retunes to next station with TP information. When newly tuned station does not have TP information for several seconds, beeps come out. When TP information gets lost at the current station for retune time, the beep sound is out-putted. I SOUND or PI MUTE While AF switching is implemented in C201 station, AF can switch to 100 MHz, which is non genuine AF (where, different PI with same AF) in short “DIP”. If a car cruises that critical area back and forth, an oscillation phenomenon can be occurred, because the different PI code can be received from 100 MHz with “XXX” PI. The car radio has special procedure to reduce even this kind of unavoidable situation however there is a limit to be escaped from this serious case perfectly. In that serious case, 2 mode is selectable as follows: 98 100 90 100 PI: XXX PI: C201 - PI SOUND mode: When above different PI sound (DIP) is heard once in a while, the DIP’s sound will be heard for a short time. - PI MUTE mode: Under above same situation, a mute sound will be heard for a short time. ETUNE L or RETUNE S mode The initial time of automatic TA search or PI search modes is selected. When PI information is not caught for retune time, the radio starts to retune to next same PI station. When same PI station does not catch 1 cyclic search, the radio goes to last station and waits for several minutes until PI code is received. ASK DPI or MASK ALL mode The AF frequency (which has different PI or NO RDS signal with high field strength) is masked during checking PI when the unit searches AF. In the case of the AF of NO RDS signal with high field strength, if the real AF is wrongly masked as DIP by some interference, the unit hesitates to search real Afs. For this reason, the unit has the user option (MASK DPI) which doesn’t mask the AF of NO RDS signal with high field strength. In MASK DPI mode, the wrong sound or long mute (according to PI SOUND or PI MUTE) can be heard from the AF station which has NO RDS signal and of which the field strength is higher than that of the currently tuning AF (station). But, these phenomenons are rare and the user will hardly hear the wrong sound in whole Europe. - MASK ALL mode: Masked the AF which has different PI and NO RDS signal with high field strength. BEEP ON/OFF mode - BEEP ON The beep is generated when every key is pressed. LIQUID CRYSTAL DISPLAY AUXILIARY INPUT The unit can be connected to a portable audio player through the AUX IN jack (13). [. . . ] SELECTING SONGS IN SINGLE STEP Press button (24) or button (2) to move to the previous song or the following song. CAUTION： ： When there are important files in the USB device, do not connect it to the main unit to play, because any wrong operation may cause files loss. SD/MMC OPERATION There is a SD/MMC interface (22) on the front panel of the unit. When you insert a SD/MMC card in the SD/MMC interface, the unit will search the MP3 files or WMA files in the card and start to play MP3 files or WMA files automatically. [. . . ]
