When unit is turned on, it's quiet for a few seconds, and then a loud noise appears, and does not go away. Only one of the pair does this,regardless of the channel assisgnment. It seems like the squelch is not working. I do not have an owner's manual. Conair FRS214

Charge or put in batteries.
Turn both radios on.
Turn the volume up.
Tune both radios to the same channel. Pick a channel that is quiet. Quiet means very little chatter and very little white noise. You can make a channel more quiet by increasing squelch but increasing squelch decreases range.
Both radios are now listening.
When you want to talk, press the talk button and say what you want to say.
Remember you are just talking to anyone listening on that channel, so be nice.
"Mon" is short for "Monitor" and is usually a feature that allows you to momentarily break the squelch (signal filter) and hear anything being transmitted on that frequency. That includes static if there's no transmissions. It allows you to listen for a weak signal that can't break the squelch threshold you have set. Some radios allow you to lock it open by pressing and holding the MON button for a few seconds. Turn the feature off my doing the same thing.
I suspect you have it in the continuous monitor mode so follow the directions for getting back into the automatic squelch mode.
AUTOMATIC SQUELCH: The FRS is equipped with an automatic squelch circuitry filtering out weak transmission and unwanted noise, usually caused by terrain conditions.
MONITOR: - This feature turns off the automatic squelch feature, either momentarily or continuously. It helps in receiving signals to its maximum range, but may pick up static signals, too.
Momentary monitor: - Press the MON button; the monitor symbol will appear. - Release the button to restore the automatic squelch.
Continuous monitor: - Press the MON button for more than 2 seconds until a beep sound is heard. The monitor symbol will appear. - To restore the automatic squelch, press and release the MON button again.
NOTE: You cannot transmit when the Monitor feature is activated.
No, the radios should be silent (squelched) when not receiving a transmission. Appliances (computers, televisions, even refrigerators) can generate enough "hash" to break the squelch and give you that "rushing" noise. Make sure that the radios are at least 4 or 5 feet apart, and try moving them to different locations to clear up the problem.
What you want to do is tighten up the squelch adjustment and that should reduce the white noise you are hearing. also keep them away from any computers, the square waves generated by them will open up your squelch annoyingly as well.
I have a UH036SX so not sure if its exactly the same. If you open up the unit, there is a large black potentiometer near the base of
the antennae. I found if I wound this counterclockwise by approximately
quarter of a turn with a small flat blade screwdriver it reduced the squelch level to a better level. I suggest wind it down until the static is gone, then increase slightly to give the best level.
Yes sir, when u will open the set u can find two potentiometers , one is for tranmitter another for receiver . Try adjusting the same ( second radio should be transmitting ) do not switch one radio without antennae it may burn ..
Will the 2 units work with each other? If so, then it could be an issue with the squelch codes.
There's usually a push button on those units that will "open" the squelch momentarily and you should then hear squelch noise and maybe get a green light to tell you squelch is open. If you have that and don't hear the noise, it could be a bad speaker.
I have the same walkie talkies and on mine I can hold down the mode/lock button and it will come off of the Rx mode. Also, you should be able to press the talk button and it will come off of the Rx mode.
The RX symbol and static noise would only appear if the squelch is down or if you are receiving something from a transmitter.
Receiving something could mean either an intelligent radio transmission from another comparable unit or this could also be spillover signals from adjacent radio transmitters strong enough to override the squelch settings normally called "splatter". At times, electronic devices could cause this effect such as RFI (radio frequency interference) from units such as a personal computer.
It is also possible that your Monitor Mode is "ON", turning it OFF would possibly resolve the issue To turn OFF monitor mode:Press the vol/mon UP or DOWN key. The RX icon will stop blinking and disappears.
In some cases, a component failure would cause this problem. Your GMR1035-2 uses an Automatic Squelch Feature, this would mean the use of a FM Discriminator Chip for Squelch Control. Most manufacturers uses an MC3357P IC chip for this purpose. This of course would require opening the unit, desoldering the suspected component and solder in a replacement. This would further require that you be familiar with electronic components, circuitry, DVM and a low wattage soldering iron. Should you not be comfortable doing this, perhaps your best bet would be to seek the services of a qualified technician.
Hope this be of some help/idea. Post back how things turned up or should you need additional information.
