How do I prevent the internal clock from bleeding into the audio?

If your clock stops at 7:30 and won't advance beyond that point, there are a few potential causes for this issue. Here are some troubleshooting steps you can take:

1. Check for Obstructions:
   • Inspect the clock hands and the area around them for any obstructions. Sometimes, a small piece of debris or interference can prevent the clock from moving.
2. Ensure Proper Power Supply:
   • If your clock is powered by batteries, make sure they are fresh and properly installed. If it's an electric clock, check that it is plugged into a working outlet.
3. Check the Movement:
   • The clock movement (the internal mechanism that drives the hands) might be malfunctioning. If you're comfortable, you can open the back of the clock and observe the movement. Look for any visible damage or issues.
4. Inspect the Hands:
   • Examine the hour and minute hands. Sometimes, the hands can get bent or caught on each other, preventing proper movement.
5. Reset the Time:
   • Try manually setting the clock to a different time. If it moves freely until 7:30 and then stops, there may be a specific issue related to that time setting.
6. Check for Mechanical Issues:
   • If the clock has a pendulum, ensure that it is swinging freely and not getting stuck. For clocks with gears and cogs, make sure they are not damaged or obstructed.
7. Consult the Manufacturer or Manual:
   • Refer to the clock's user manual for troubleshooting tips specific to your model. If you don't have the manual, you can often find it online on the manufacturer's website.
8. Professional Repair:
   • If the issue persists and you're unable to identify the problem, consider contacting a professional clock repair service. They have the expertise to diagnose and fix mechanical issues.

Remember to exercise caution when working with the internal components of a clock, especially if it involves opening the back or disassembling parts. If you're unsure or uncomfortable doing so, seeking the assistance of a professional is recommended.

Yes - although Bose doesn't really publicize the fact, there is an internal line fuse in each Wave. Location varies by model and date of manufacture, but the fuse is easy to spot once you open the radio case.

It could be anything as the coins could have shorted out any of the parts. There's also the possiblity that something, even a coin is still inside. I would take off the top and see if you can see anything, objects or broken parts and see if the internal fuse is OK.

There are dozens of processes occurring continuously in any TV set that involve very fast rise and fall times of signals which produce what is called 'harmonics' that are multiples of the frequencies of the different circuits. All TVs are sources for garbage extending across just about every band of frequencies that exist. There are standards set by the US Federal Communications Commission regarding how far these signals may carry and are often ignored by electronic manufacturers since it is fairly expensive to ensure that circuit board design and shielding are effective in eliminating or reducing these stray signals.
Computers are generally far less a problem since they are encapsulated in a steel housing that can prevent most radiation from the internal circuits from escaping; consumer receivers of all kinds have a lot of 'leaks' due to their construction and the use of plastics that are totally transparent to radio waves unless coated with metalization, not commonly found in consumer goods.

I repaired mine recently. Check transistor Q4 for an e-b short. The replacement costs less than $1.

Here's a link to the manual at Pioneer's web site.

Here's how you set the time (from page 16 in the manual):

1: press SOURCE and hold until the unit turns off.
2: Press AUDIO repeatedly until the clock appears in the display
3: Press (left arrow) or (right arrow) to select the segment of the clock display you wish to set (hours, minutes)
4: Press (up arrow) or (down arrow) to set the clock.

- To cancel clock settings, press BAND
- to save clock settings press AUDIO until the display stops blinking

0) Read the last answer first :) it is the most likely.

1) Make sure that the noise is electronic, not mechanical,

a) Electronic noise comes from the speaker

b) Mechanical nose originates in the clock
(older mechanical clocks only)

c) Clocks come in 3 varieties:
Electronic
Mechanical "Flip Leaf"
Mechanical "Motor/ Gear" driven.

2) Assuming that your clock is electronic, there are
only two possibilities for causing static.

a) Extremely intense electromagnetic interference,
as in radio waves, from a thunderstorm or a powerful
transmitter nearby, such as a HAM radio or even
an active cell phone.

Intense electro-magnetic waves can be picked up by
internal wires within the radio which act as an antenna,
rectified (demodulated) by internal diodes and transistors,
filtered by internal capacitors and the speaker's inertia,
and still present enough audio frequency energy to the
sensitive speaker coil to be "quite" audible and irritating.

This can happen even with the power off, when the
interference is so strong that it needs no amplification !

This happens to my computer speakers, every time my
cell phone rings, and starts transmitting a return signal.


3) The power switch is intermittently shorting causing a small
amount of DC power to enter the radio, the more intermittent
the switch, the more noisy it gets.

This causes my old clock radio to turn on by itself when its
not supposed to.

The cause of the problem in either in the main power/ mode
switch, or in the clock driven switch or relay.

4) Old switches and volume controls get oxidized with time
and/or bridged by products of corrosion. The simple solution
is to clean them using a good aerosol contact cleaner,
available from an electronic shop for about 10 bucks.

Simply spray the cleaner into all the switches and controls,
while vigorously exercising each switch or control back and forth.

Make sure that you use a safe "electronic cleaner" designed
for the job. It must be safe on plastics, non-conductive, good
solvent and it must evaporate quickly. Don't breath the stuff !!!

Typically the spray will contain TF (tri-fluoro-ethane), or some
other freon substitute.

Freon (Di-fluoro-di-chloro methane) is bad for the ionosphere,
now illegal in most countries for that reason.

Also stay away from Carbon-Tetra-Chloride, which is
VERY toxic.

Do NOT improvise, or use acetone or alcohols, which may (will)
melt the plastic, causing the controls to permanently seize.

Get electronic contact cleaner from an electronics hobby shop.

Good luck. Martin

I think you press and hold the band button then press the display button
