Question about Motorola CLS 1410 (4 Channels) 2-Way Radio
I have a Motorola CLS 1410 that emits a rather loud beep after you release the Push to Talk button. It doesn't matter if you are using headphone mic or just using normally. The others I have do not make this noise and I have had no success in finding a cause or solution to this. Any ideas?

If indeed radio #1 has a mic problem, this may be confirmed by trying an external speaker/microphone plugged into the accessory jack. If still a no, then its not the mic but possibly the modulator circuitry. If there is transmit audio with the external mic and hence internal mic is defective, the unit would have to be pried open and the defective component replaced. The internal mic is normally an electrofet 2-3 terminal soldered to a shielded wire and physically attached to the front plate.
Alternately, another possibility is that radio #2 has its Interference Eliminator Code enabled/activated. This is indicated by the presence of small sized digits on the top right of display. If this is the case and no similar digits are displayed in radio #1, then radio #2 will not allow any received transmission to be heard. Along the same line of reasoning, if the code is activated on both radios signified by the presence of the 2 small digits, and radio #1 has a problem with its CTCSS (code) generator, then it would also prevent reception of radio #2. A way to verify this is by deactivating/disabling the Interference Eliminator Codes on both radios.
On certain occasion, it is also possible that radio #2 has a defective speaker. You should be able to verify this by plugging in an external speaker to the accessory jack of radio #2.
Hope this be of some help/idea. Pls post back how things turned out or should you need additional information.
Good luck and kind regards.

The radio has possibly been damp or wet. Take the battery pack out of the radio and allow the radio to dry, or to speed the process try using a blow dryer on a low setting.
Check your programming and be certain your large and small numbers match one another when you get ready to try the radio again.
Here is a manual which most closely matches your radio type: http://www.usersmanualguide.com/motorola/2-way_radio/t280

Beeping when pressing the PTT can be a sign of low or bad batteries. To check to see if this is the problem, move a battery from one of the working radios over into one of the problem radios and see if it solves the problem. It takes more energy to Transmit than to receive, so your radio may receive transmissions, but not be able to transmit. If this is the problem, replace your rechargeable NiMH battery packs. Charge the radio completely (always with the radio shut off. Batteries have an 18-24 month life expectancy.
If this does not solve the problem, check your chargers. Clean the battery contacts and charger contacts with a pencil eraser. Replace any non-working chargers.

Generally a constant beep is the sign of a low or bad battery. However, it is noted the TalkAbout 250 is operated with AA batteries, and it is likely you have considered this and changed batteries. You might check your battery contacts, and clean them with a pencil eraser to assure they are making good connection. Otherwise, you may have a failing radio.
