When press hand piece button loud beeping noise can hear the person talk **** cant talk back hand peice good tried on another uhf

In the case of your radio, this answer is incorrect if you are getting them after digital transmissions. On the Yaesu FTM-400XDR to turn off the beep after someone transmist you want to go to the setup screen. then press the TX/RX button. Then Press Digital button. Then set option 4 Standby Beep to Off.

Turn up your SQUELCH button when no one is talking until the static noise just goes away.

Now your set will remain quiet until someone talks.

If you set the squelch too high it will also cut out the people talking, so always try to have it set just slightly above the background static level.

Good luck.

Hold the power button down for a few seconds until it turns on. The power button has a symbol that looks like a circle with a line in the middle.

I have the same sort of problem...kinda..lol. My Vtech sorta 'cuts out' when there is noise at my hosue. The person I'm talking to can still hear me but I can't hear them. If my son starts crying or there's any other loudish type noises on my end, it's like the phone is trying to cutout my background noise, but all it's cutting out is the person talking to me. It's not that the noises in my house are loud and I jsut can't hear the person I"m talking to, b/c if i cover the mouth peice then no matter how loud the sound in my house is i can still hear the person i'm talking to but I HAVE to keep the mouth peice covered. It's really annoying!

Could be that the headset has been muted by accident. To unmute, tap both volume buttons at the same time until you hear a tone or kind of beep.

5 beep error means that the waste ink tank is full. You can reset the counter to make it print by doing the following: You have to be exact. If you make a mistake in any of it, just go back to the beginning and start it all over.

1.Unplug the power cord from the printer

2.Hold down BOTH the POWER and RESUME button at the same time and then plug the power cord back in. Keep holding down the buttons until the printer finishes its powering up noises.

3.After the printer is quiet, release the POWER and RESUME buttons. Then hold down the RESUME and CARTRIDGE buttons at the same time with one hand, and press the POWER button with the other. KEEP HOLDING DOWN the RESUME and CARTRIDGE buttons until you hear 2 beeps. They will come quickly together and one beep will be longer than the other. Listen carefully, as they are not very loud.

4. Once you hear the 2 beeps, release both buttons.

5. After both buttons have been released, then press the CARTRIDGE button 15 times. You will hear a beep each time it's pressed.

6. After you finish pressing the cartridge button 15 times, then press the RESUME button one time. The printer will beep and shut off.

7. Turn the printer back on by pressing the POWER button. The printer will work fine now. The waste ink will have been reset to 50% full.

There are two different kinds of beeps you can control, the "roger" beep and the "button" beeps. Below is an excerpt from the owners manual explaining the simple procedure.

“Roger” Beeps/Talk Confirmation Tone
When you turn this feature On, your two-way radio transmits a unique tone when
you finish transmitting. It’s like saying “Roger” or “Over” and lets others know
you have finished talking. If the person you are talking to does not hear the talk
confirmation tone, you can enable it by pressing and holding + (plus) as you turn On
your radio. Now, whenever you release the PTT, you let your friends know you have
finished talking by transmitting a “Roger” Beep tone. “Roger” Beeps will be
disabled as the Default Setting.
Note: To toggle the Talk Confirmation Tone feature, turn your radio Off and then
back On while pressing and holding + (plus) .

Button Beeps
Every time you press a button on the front of your radio, it beeps unless you turn
Button Beeps Off. To turn Button Beeps Off, turn your radio On while you press - (minus) and
hold . To turn Button Beeps back On, turn the radio Off and then back On again
while you press and hold the - (minus) . On is the Default setting.

If it's in warranty, I would send it back. It sounds like a problem with the built-in amplifier and possibly other components.
The squealing and echo is down to gain being too high, if you cannot set this on the phone, then it's a fixed value in the hardware. If you can, lower the gain. As for not being able to end the call, what about pressing the "c" button or the green button again?

While speaking to one person, press the "conf" button... Wait for a beep beep, hit 9 then dial the other number... talk to the new person... press "conf" again... talk to everyone

just decrease the ear piece volume frm settings in ur fone.it will b done.
