I recently switched the boards from one of my Pro-95 to another plastic case. I put it all back together nicely, but the speaker does not work. All is connected as it should be. No loose wires anywhere. I took the case from one Pro that worked great but the case had been run over and switched it with my other Pro that worked great except for "Trunking". Oddly enough, the speaker no longer works on either one. I don't get it? Help!
Re: Pro-95 Internal Speaker not working. External OK
One way to test the speaker, Unsolder 1 of the wires to the speaker terminal, take an ohmmeter and measure the + and - leads of the speaker . if the speaker reads 8 to 32 ohms it is probably not the speaker, if the speaker measures less than 2 ohms or infinity then it is shorted or blown with an open connection. simply replace the speaker with a comparable size, wattage and impedance. I had a similar problem with my pro95, the speaker simply was bad, I replaced it and it was fine.

Re: Pro-95 Internal Speaker not working. External OK
Odd, indeed. I imagine that you have the speaker plugged into the mainboard, so the problem may be either the speaker itself or the external speaker jack, as it's possible a connection between the jack & the PC board got damaged when you disassembled & reassembled the scanner. You can test the speaker by unplugging it from the board & checking it with an ohmmeter, it should read low resistance (@ 8 ohms). You can also use a continuity tester to ascertain that the speaker isn't an open circuit.

Does it have an external speaker plugged in the back? If so try unplugging it see if the internal speaker works, if it doesnt have an external speaker plugged in try one, maybe the internal speaker went bad from moisture.
it is possible that the PA speaker output is intended for a normal (unpowered, unamplified) speaker. Perhaps in your case the audio you hear from the PA speaker is only signal leakage from the PA Speaker connection.
To know.. connect a regular speaker to the PA speaker connector (any speaker, home audio, old car 6x9....). If the PA works and drives the temporary speaker OK, and you hear no CB receive, then the PA output is for a normal speaker, with leakage of CB audio.
It is just a guess, but easy to try.
I had the same problem. Because I live in Brazil and this headphone is not sold here (I bought it in Canada), taking it to assistance wasn't an option.
I was so annoyed that such a minor issue was keeping me from using an otherwise perfectly working headphone, I went ahead and tried to open it. Obviously I couldn't do it, got mad and ended up ripping the whole thing apart. Luckily I only screwed up the plastic case so it still works.
Anyway, turns out it's just a 3mm piece from the external power switch that broke, so it wasn't able to push the internal power switch. I removed the external switch and put the (rest of the) plastic case back on, I only need a small tip, like a mechanical pencil, to turn it on and off.
If you don't know what else to do and won't bother to send it to assistance, I recommend just using something like a utility knife to cut off the external power switch (without opening the whole thing) so you can reach the internal switch.
"Speaker: Internal/External" controls which speaker (built-in or external) is available. Set to "Internal" for normal operation of the internal speaker system. When connected to external speakers or an external audio system, the speakers can be turned off by setting this function to "External."
From reading this I see that the speakers may be internal because the setup allows to switch between external or internal. A mounted speaker is either permanent, part of the case, or has something that the speaker case slips into. I had one like that. You simply lift them and set them else where. How far they can be moved will depend on the wire. The wire is either attached internal through the back or attached via connectors on the back. That can either be loose wire or RCA plugs. Normally the wire coming from the speakers is attached internal, making the removal of them impossible. The wire is usually 3 to 6 feet long. You can buy an external speaker wire that has RCA plugs (and or plain wire) that will attach to the existing speaker wire and TV.
Hi, my name is John. try putting a external speaker in back of radio and see what happens, might need to replace internal speaker, or something internal. Let me know, I will post the process here......Hope this was helpful..
it does not have a battery but a large capacity capacitor that works like a battery. that could be the trouble but rarely happens on new units. the battery is located in the display board near the FL display. odl type uses like a button battery but newer model is just like an ordinary capacitor
Well, this is a bit late, but if you still have the N10, you must charge the internal battery enough for the external battery to work. You can run the internal battery dead enough that it won't recognize the external battery in this model. Make sure, of course, that the battery switch is on, and that you have the correct charger.
It is possible that:
1. You may have recently installed an add-on/external device such as a multimedia keyboard which changed the audio output from internal to external;
2. The laptop's internal speaker might have gone dead (highly unlikely but still a possibility) - try plugging in external speakers or a headset and check;
3. Most if not all laptops uses a female stereo babyphone jack to connect to external speakers. This jack has a built-in switch that cuts off internal speaker if an external is plug in. If you are using eternal or headset from time to time, it is possible that the switch might have locked to external and does not switch back to the internal;
4. You may have a hardware issue specifically the sound card/chipset. This of course would require an inshop repair which may be better off with an authorized service center. At worst is have the entire laptop replace if it is confirmed to be a hardware issue.
Hope this be of some help/idea. Post back how things are or should you need additional information.
Good luck and kind regards.
