CD-BA1500H • FM Notes: 1: Description of the "FM IF Adjustment" is not carried on this Manual. It is because the IF coil in the FM front end section has been best adjusted in the factory so that its further adjustment is not needed at the field. When replacing the FM front end assembly, no adjustment is needed either.

– 16 – PI—identify Compare the field strength of current receiving signal. Is receiving signal stronger than signal which has same PI cord and is already memorized to preset memory ahead of this receiving time? Yes Comparing PI cord same or not? between current receiving PI and before PI which is already memorized by ASPM on this time. Yes RDS signal or not? Yes If count 2nd OK? Yes If count 1st OK? Yes SD (TUNE) DET out OK? Begin to scan start 87.50 → 108.
PAGE 11
CD-BA1500H • ASPM SCAN: 87.50MHz → 108.00 MHz. • Only RDS signal is memorized by ASPM because RDS signal has PI code and is suitable and convenient for ASPM operation. ASPM Comparing field strength, only one strongest RDS station is memorized of all stations (repeater relay stations) that have same PI code. f3 P 1 (PI code) PS 1 (Station Name) f5 P2 PS 2 f4 --- f1 f2 --- Each PI has AF’S list by individually. Exa: P1 has f1, f2, f3 (same PTY). Same PI code — freq: different P2 has f4, f5 (same PTY).

Note: When the TP and TA appear at the same time, an announcement is being made. When only the TA appears, an announcement is not being made. RDS is a broadcasting service which a growing number of FM stations are now providing. It allows these FM stations to send additional signals along with their regular programme signals. For example, the stations send their station names, and information about what type of programme they broadcast, such as sports or music, etc.

CD-BA1500H NOTES ON SCHEMATIC DIAGRAM • Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type. • Capacitor: To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad.
