SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schematics or
by special notes in the part lists. Use only replacement parts that have critical characteristics recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the unit to the customer. Use the following
checks to perform these measurements:
A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage
current tester or a metering system that complies with American National Standards Institute (ANSI)
C101.1 “Leakage Current for Appliances” and Underwriters Laboratories (UL) 1492 (71). With the
unit AC switch first in the ON position and then in OFF position, measure from a known earth
ground (metal water pipe, conduit, etc.) to all exposed metal parts of the unit (antennas, handle
bracket, metal cabinet, screwhead, metallic overlays, control shafts, etc.), especially any exposed
metal parts that offer an electrical return path to the chassis. Any current measured must not exceed
0.5 milliamp. Reverse the unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS
NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT
MUST BE ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper wire
between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure the resistance with an ohmmeter between the jumped AC plug and each exposed metallic cabinet part on
the unit. When the exposed metallic part has a return path to the chassis, the reading should be
between 1 and 5.2 Meg ohms. When there is no return path to the chassis, the reading must be
“infinite”. If it is not within the limits specified, there is the possibility of a shock hazard, and the unit
must be repaired and rechecked before it is returned to the customer.
ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)
DEVICE HANDLING
This unit contains ESDS devices. We recommend the following precautions when repairing, replacing or transporting ESDS devices:
• Perform work at an electrically grounded work station.
• Wear wrist straps that connect to the station or heel straps that connect to conductive floor mats.
• Avoid touching the leads or contacts of ESDS devices or PC boards even if properly grounded.
Handle boards by the edges only.
• Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert unprotected
devices into materials such as plastic, polystyrene foam, clear plastic bags, bubble wrap or plastic
trays.

1.0 Overview
The Wave® Radio/CD is an AM/FM tuner, single disk CD player, and powered speaker system. In
addition to the internal sources, external devices such as a tape deck can be connected through the
unit’s AUX input. An infrared (IR) remote control can be used to control the unit.
2.0 Power Supply Electronics
AC mains are connected through the line cord attached to the polarized jack J1. The neutral wire of
the line cord is used as an FM antenna coupled by C1. L1 and L2 provide isolation between the FM
RF input and the transformer T1. A slow acting fuse F1 is connected between J1 and the non-
polarized jack J2 to protect against faults.
Transformer T1 is a round core (R-core) transformer with one primary winding (unique for different
AC mains voltage requirements) and three secondary windings. The primary has a series thermal
fuse to protect against overload and faults. Two of the three secondary windings have center taps.
Polarized jack J3 ensures the correct connection of the pins from T1.
The first secondary winding of T1 provides the main audio power V and the CD motor power
VMOTOR. Bridge rectifier BR1 serves dual-purposes: it full wave rectifies the AC from two ends of
the first secondary (without the center tap) (creating V when filtered by C6; part of it also rectifies
through the center tap creating VMOTOR (about V/2)) when filtered by C16. The quiescent voltages
of V and VMOTOR are about 15VDC and 7.5VDC, respectively. V provides power to the uC elec-
tronics (+5V) and the CD electronics (+5VCD). A 9V battery connected to J200 also provides
backup power for the uC in case of a power outage. The switching between V and BAT+ is auto-
matic through D207. +5V is regulated by U202, a voltage regulator with low dropout voltage and low
quiescent current characteristics. Such characteristics are necessary to extend the battery life.
+5VCD is regulated by U203. R212 is a dissipating element for U203.
The second secondary winding of T1 provides power to the audio and RF electronics: a positive
voltage rectified by D201 and filtered by C205; and a negative voltage rectified by D200 and filtered
by C202. The positive voltage is regulated by U201 to generate +10V for the audio electronics. R208
is a dissipating element for U201. The uC controls +10V and +5VCD through Q207, D202, Q206
and Q208. In the off mode and battery backup mode the uC releases TURNON, turning off Q206
and Q208 and consequently +10V and +5VCD. In any other mode the uC asserts TURNON. The
negative voltage is regulated by U200 to provide -15V for the audio electronics. A reference voltage
of -20.6V is created by the 5.6V zener diode ZR200 and R201 between -15V and the negative
voltage. This -20.6V reference is buffered by Q202 to make -20V for the VFD electronics. The VFD
“center tap voltage” CT is generated from -15V by Q201. The uC controls the brightness of the VFD
partly by changing the CT voltage. It does so through AUD-DATA, Q210 and the resistor network
R231 and R232. AUD-DATA from the uC is multiplexed and filtered by R230 and capacitor C231.
Normally in a bright environment, AUD-DATA is filtered to be high so Q210 is turned off. The base of
7
Page 9
THEORY OF OPERATION
Q201 is at the same voltage as -15V. Consequently CT is at about -14.4V. In a dark environment,
AUD-DATA is filtered to be low so Q210 is turned on. The presence of +5V at the resistor network
changes the voltage at the base of Q201. CT is increased to about -9V, consequently reducing the
display brightness.
The third secondary winding of T1 provides AC power to the VFD filaments. It is nominally 5.3VAC.
The center tap is connected to CT so that the VFD filaments are negatively biased.
R200 is used to protect Q201 at power up. R207, R211 and R214 are fusible resistors protecting
against faults.
A line frequency signal (60 Hz) is generated from the secondary MAIN. MAIN is filtered by R205
and C215, clamped by D206, and buffered by Q200. 60 Hz (60 Hz or 50 Hz depending on the AC
mains) is used by the uC to keep time and to detect a power failure.
3. Control Electronics
The embedded micro-controller (uC) used in this system is a Toshiba TMP87xx14F, where the xx
digits define whether it is an OTP or a masked part. The main system power supply and the battery
are connected to a low dropout low quiescent current regulator through D207; when the main power
supply drops below the battery level, the battery will drive the uC. U403 is an automatic reset chip
that monitors the 5 volts at the uC and will pull pin 29 of the uC (RESET) low if the voltage drops
below 4.75 volts; it also supplies the power-on reset pulse. CF401 is an 8.00 MHz ceramic resonator
with built in capacitors.
U401 is an Electrically Erasable Read Only Memory that is used to store presets, AM and FM stop
levels, the stereo threshold level and other pieces of data. All of the series resistors and shunting
capacitors used on the signal lines leaving the uC are helping control conducted RF emissions from
the uC. D401 is a light sensor that in combination with R420 provides a voltage related to the light
level in the room. This voltage is read by the analog to digital converter at bit 7 of port 6 and is used
in the VFD dimming algorithm. Q401 is the infrared detector that works with the IR remote. The
series resistors and shunting caps tied to the pins of the VFD are used to control RF emissions. The
shunting resistors connected to six of the VFD control lines are used to help discharge the VFD
lines when those particular segments or grids are to be turned off. Q405 and Q406 increase the
current drive for two grids.
KEYIN1 through KEYIN4 and KEYOUT1 through KEYOUT6 are routed to the button board through
J403 and form a button matrix. Normally, the uC holds the KEYOUT lines low and pins 59 through
62 of the uC, which correspond to the KEYIN lines, will be pulled low through R468, R469, R470
and R430. The uC has internal 80k pull downs to -20 Volts on pins 59 through 62, so the voltage
there will actually be less than 0. The transistors Q400, Q402, Q403 and Q404 are used for level
shifting and current gain to overcome the resistance of the carbon ink button board. When a button
is pressed, a KEYOUT line will pull current through the base of the corresponding KEYIN transistor
and drive one of the pins on the uC high. The uC will now begin scanning the KEYOUT lines by
pulling each line individually high one at a time. This way, when the KEYIN signal disappears the uC
will know the corresponding KEYOUT line and which button in the matrix is pressed. The uC can
now execute the desired command.

THEORY OF OPERATION
4.0 Audio Electronics
The two internal sources (CD and tuner) and the AUX input are routed to the audio multiplexer/
volume control chip U605. U605 selects one of the three inputs and routes the signal to pins 7 and
17 (right and left). These two signals are AC coupled to J600 as Line Outputs. Q602 and Q603
buffer a signal (BUZZER) from the uC that is summed with the left channel for use as an alarm. The
left and right signals then pass through matching EQ sections using R655, R656, C645, C646 and
R660, R657, C665, C666. These sections normally provide bass cut at loud volume settings. These
EQ sections increase the deep bass for lower volume settings. This is the dynamic EQ for the
product. The final stage of U605 is the volume control. U605 provides 80 dB of attenuation in 64
steps of 1.25 dB. The variable level signal is output on pins 24 and 25.
The audio signal is then split into two paths. The right and left signals are routed through U600 and
one quarter of U601, which provide active filtering for the left (full range) speaker output. The right
signal is also routed through three-quarters of U601 which provides active filtering for the right
(Twiddler
The two audio signals are fed to the power amplifier U1. U1 is a bridged stereo power amp used for
the right and left channels. The U1 outputs are routed through J5 and J6 to the left and right drivers
respectively. U1 also contains a clip detector that is output on pin 4. This signal (COMP) controls the
bias current of U603. When the amplifier is clipping, the bias current of U603 is increased. The
change in gain of U603 reduces the bass frequency response of the left channel EQ. This is the
compressor for the product.

) speaker output.
Q4 is an amplifier that is connected to the Twiddler. It amplifies the signal BUZZER only when the
unit is not powered. The power for this comes from the nine-volt battery.
5. Tuner Electronics
There are two major ICs in the tuner section: U300, an AM/FM radio chip with a built in stereo de-
multiplexer, and U301, a Phase Lock Loop (PLL) chip. The main system embedded controller (µC)
talks to the PLL chip using signals AUD-DATA, PLL-DATA, AUD-CLK and PLL-CE. The µC controls
whether the tuner is in AM or FM mode by forcing pin 8 of the PLL either high or low; a low puts
U300 in AM mode and disables power to the FM-TUNER and a high puts U300 into FM mode and
turns on power to the FM-Tuner via Q300 and Q301.
In FM mode the frequency of the local oscillator (LO) located in the FM-TUNER is adjusted by the
signal FM_TV which is applied to pin 5 of the FM-TUNER. The LO is then output on pin 8 and
routed back to U301 via C338. The PLL then compares the scaled frequency/phase of the LO
against a reference which is a division of the 7.2 MHz oscillator composed of U301, C341, C342
and CF303. The result of this comparison determines the density and polarity of the phase pulses
which are output on pin 16 of U301. The phase pulses then go into the loop filter composed of a
MOSFET inside of U301 (Ain and Aout) and the discrete components attached to pins 16, 17 and
18. The loop filter integrates the phase pulses to form the DC control voltage FM_TV thus complet-
ing the LO control loop.
Inside the FM-TUNER, the LO is mixed with the RF signal, coming from the F-Connector J300 or off
of the AC line cord neutral wire via C1, to produce an IF signal centered at 10.7 MHz that is output
on pin 7. The IF signal then passes through ceramic filter CF300, the common emitter amp contain-
ing Q303, CF301 and is then routed into U300. Inside the chip the IF signal is limited and detected.
The resonant LC circuit on pin 9 is part of the detector circuit. After detection, the stereo signal is
9
Page 11
THEORY OF OPERATION
then de-multiplexed inside the chip and the stereo channels are output onto pins 16 and 17. The
ceramic resonator CF302 is used by the stereo de-multiplexer’s VCO. C321, C320 and R315 form
the loop filter for the de-multiplexer’s PLL. The left and right channel signals are then routed through
the 19 kHz pilot reject filters composed of T303 and T304. The µC makes stop and stereo threshold
decisions based on the level of the S-METER signal which is read by the analog to digital converter
in the µC. The µC forces the radio into mono mode by telling U301 to force its pin 9 low.
For AM, the Local Oscillator is composed of the LC resonant circuit, which is half of D304 and T302,
and an amplifier in U300. The AM LO signal comes out of pin 30 of U300 and is fed into U301 via
R330 and C337. The PLL chip compares the scaled LO frequency against a division of the 7.2 MHz
oscillator and outputs the appropriate phase pulses from pin 16 into the loop filter. The tuning voltage comes out of the loop filter through R309 and appears across pins 1 and 2 of the varactor diode
to complete the AM LO control loop.
The inductance of the AM Bar Antenna at pins 3 and 4 form a parallel resonance with the capacitance between pins 3 and 2 of the varactor diode producing frequency selectivity at the antenna.
The RF at pin 1 of the antenna is routed into pin 27 of U300. The input circuitry at pin 27 is biased to
3.6 volts (Vreg) through R308 and the coil wound between pins 1 and 2 on the antenna. Inside the
chip, the RF is amplified and mixed down to an IF (intermediate frequency) of 450 kHz. The IF is
output on U300 pin 2 and routed to the IF filtering in T301. The filtered IF then enters U300 at pin 5
and passed through audio detection in the chip. The audio is then output onto pins 16 and 17.
6.0 CD Electronics
The CD circuitry consists of four major sections: the analog signal processor (ASP) U500, digital
signal processor (DSP) U501, power driver U502 and the CD mechanism. U500 contains the RF
amplifier and servo control circuits. U501 performs EFM demodulation, CIRC decoding, digital
filtering, D to A conversion and low-pass filtering. It also extracts the subcode Q data (track #, time,
etc.).
U500 receives its input signal (through J500) from the mechanism’s photo diode pickup. The inputs
A, B, C and D are added together and amplified. The RF amplifier output appears on RFSM (U500,
pin 41). This signal is the familiar eye pattern. This signal is sent to EFMIN on U501 pin 10 where it
is sliced for EFM demodulation. The sliced output appears on EFMO (U501 pin 9). A low-passed
version of this signal appears on SLC (U500 pin 43) and is used as a DC bias for the RFSM signal.
The RFSM signal is peak detected and compared to a reference to determine if there is a signal
being received from the disc. The output appears on DRF (U500 pin 54). This signal is used by the
µC to determine if the lens is in focus. The envelope of the RFSM signal is used to determine when
the laser crosses a track boundary during track access. The HFL signal (U500 pin 37) conveys this
information to U501.
The B+D signal (FIN2) is subtracted from the A+C signal (FIN1). This produces the focus error
signal FE (U500 pin 20). This signal is amplified and filtered by the focus servo amplifier within
U500. It then appears as an output FD (U500 pin 16). The FD signal is fed to U502. U502 generates
a bridged output which is used to actuate the focus coil (J500 pins 10 and 13).
The E and F signals are buffered by U500. E is then subtracted from F and this difference is the
track error signal TE (U500 pin 7). TE is used by both the anti-shock circuit and the tracking servo.
TE is filtered at the SCI input (U500 pin 9) to determine if the system has had a shock. If this occurs,
U500 increases the track gain internally to compensate for the shock. The TE signal is amplified and
filtered by the tracking servo amplifier within U500. It then appears as an output TO (U500 pin 15).

Page 12
THEORY OF OPERATION
The TO signal is fed to U502. U502 generates a bridged output which is used to actuate the track
coil (J500 pins 11 and 12).
The TO signal is also used as an input to the sled servo. This signal is filtered and fed to the sled
servo amplifier on SLEQ (U500 pin 28). This signal is amplified and added to the SLED signals from
the µC. The sum appears on SLD (U500 pin 29), which is fed to U502. U502 generates a bridged
output to drive the sled motor (J502 pins 5 and 6).
The Constant Linear Velocity (CLV) servo is regulated by comparing the bit rate to a fixed reference
frequency in U501. The error signal appears at U501 pins 12 and 13 (CLV+ and CLV-). These
signals are subtracted and the difference appears on SP (U500 pin 23). The SP signal is filtered and
amplified. The signal then appears at the output on SPD (U500 pin 27). SPD is fed to U502. U502
generates a complimentary output which drives the spin motor (J502 pins 1 and 2).
U500 regulates the laser power by monitoring the LDS input (J500 pin 8). This signal is compared to
a reference to generate the proper drive signal on LDD (U500 pin 62). This signal is buffered by
Q500. The Q500 output is amplified by Q501. Q501 drives the laser diode output LD (J500 pin 6).
U500’s main DC reference voltage is VREF (U500 pin 58). This voltage is nominally 2.5V.
U500 receives servo control commands from the µC on the serial bus (U500 pins 51, 52 and 53).
These commands are used to start focus offset cancellation, track offset cancellation, E/F balance
adjustment, focus initialization, laser ON/OFF and 8/12 cm spindle gain.
The DSP clock is derived from a 16.9344 MHz crystal oscillator (CF500). U501 divides this clock by
four to generate a 4.2336 MHz signal that is output as the signal 4.2M (U501 pin 61). 4.2M is used
as a system clock by the ASP.
U501 receives servo control commands from the µC on the serial bus (U501 pins 57, 56 and 54).
These commands include track jump, focus start, disk motor start/stop, muting on/off and track
count. The tracking servo is controlled by the TOFF and TGL outputs (U501 pins 17 and 18). Track
jumps are created by signals on the JP+ and JP- lines (U501 pins 19 and 20). Track jump detection
is based on signals from U500 on the HFL and TES inputs. U501 removes the subcode Q data from
the bit stream and makes it available to the µC. The µC extracts track, time and table of contents
information from the subcode Q.
U501 receives its EFM input from U500 on EFMIN (pin 10). This signal is sliced, EFM demodulated
and CIRC decoded. The digital audio signal is passed through a 4x over-sampling digital filter, D/A
converter and low-pass filter. These outputs appear on RCHO and LCHO (U501 pins 40 and 37).
The audio signals are routed to U605.

ABBREVIATED OPERATING INSTRUCTIONS
Note: Refer to the Bose® Wave® Radio/CD owner’s guide 250723 for complete operating instruc-
tions.
To turn off the display- With the system off, hold down CD Mode and press On/Off to turn off the
main display. The display only lights briefly when you press any button and while the alarm is sounding.
Repeat this step to turn the main display back on.
To set AM/PM (12 hour) or Military (24 hour) time- With the system off, hold down Alarm Setup
and press On/Off to switch between AM/PM (12 hour) and Military (24 hour) time formats.
To adjust the display brightness- The display dims automatically to medium or low brightness, as
appropriate for low light room conditions. You can adjust the brightness setting of the display for both
strong light and lowest light environments, but not for the medium light setting. Turn the system off
before setting the brightness levels.
In a strong lit room, hold down CD Mode and press Volume up or down to adjust the setting
between 6 and 9 (it is preset to 8).
In a barely lit room, hold down CD Mode and press Volume up or down to adjust the setting
between 1 and 6 (it is preset to 2).
If you do not want the system to dim automatically, set both levels to 5.
To manually tune in a station- Tap either Track/Tune button quickly two or more times to tune the
frequency in small step. Or, press and hold either Track/Tune button until the desired station is
reached. Then, you can press the button to adjust the frequency in small steps. After manually
tuning, wait two seconds for the system to return to seek mode.
To set the alarm volume- While the selected alarm is flashing, press Volume up or down to set
the alarm volume, from 10 to 99. The selected alarm flashes for ten seconds.
To set continuous music- In CD play mode, to select a source to play automatically after the CD
ends, hold down Alarm Setup and press FM, AM, or AUX on the control panel only. The selected
source lights briefly on the display. Cancel continuous play by pressing CD stop or On/Off.
