How can you test a band radio earpiece cord - Motorola CLS 1110 (1 Channel) 2-Way Radio

Very strange! Assuming no programming has changed: check that all earpieces are tight into the radio. Unplug, check for audio without an earpiece and replug into radio. Make certain your batteries are FRESH (less than 1 year old) and fully charged. I am assuming you are using earpieces approved for the Motorola radio. Many speakers do not work and several earpieces are not designed well. Stay away from the auction site cheap ones. You get what you pay for, including failures. For several audio jacks to fail at once would be very unusual. Try a new earpiece. I suspect earpiece failure more than anything. All tests after this require checking programming and/or taking the radio apart.

Press Menu button, then scroll with Up and Down buttons until you find the setting you need. Press Menu Button again and cursor will move down to the settings. Use Up/Down buttons to adjust the settings and then press Menu button to save and exit .

The best test is a radio with a known good or new accessory jack. Cords to earpieces and other audio accessories are the common failure part of the device. They can be damaged at the grommet (near the plugs) by users who repeatedly plug and unplug them. The wiggling side-to-side motion can break solders and wire connections. Also some users will twirl the earpiece on the wire when not in use, a bad nervous habit which can break the wire in the cord. Earpiece are not considered repairable, and simply need replaced when they fail.

The other thing you could be having trouble with is the audio accessory jack on the radio. This can be damaged by repeated use, and can get wobbled out over time. Each seems to have their own "sweet spot", sometimes simply swapping earpieces with another radio will make a previously failed device work great.

On the CP200 radio it is strongly advised to use the optional audio accessory retain to hold any plug in place. Then you can leave your device plugged in and save wear-n-tear on the jack.

Hi, You can get the unlock code for a Samsung C168 from www.wickedunlock.com at affordable cost with easy unlocking instructions.

The JVC HA-NC250s are a new version of their previous model 100, and JVC claims that they will cancel up to 85% of ambient noise, coupled with better sound. In this case, JVC claims up to 16.5 db reduction at 150 kHz. These on-the-ear headphones are very lightweight at 5.3 ounces and are extremely comfortable. The head band has a reasonable amount of sliding expansion for bigger heads, and the oblong ear pieces themselves rotate and fold flat for storage. JVC uses memory foam on the earpieces, as well as double housing, for extra noise isolation. The earpieces have 40 mm neodymium drivers, which are the same size and type that the Creative Aurvanas offer.The JVC HA-NC250 noise canceling headphones. Note the ear-cushion instruction tab that explains how to replace the hidden battery.

The NC250s come in a semi-rigid black case with a dual airline-plug adapter, a mini-to-RCA phono plug adapter and a 4' detachable headphone cord. JVC includes one AAA battery, which should last approximately 50 hours. A simple sliding switch on the right side turns the noise reduction on along with a small red LED. Learning how to add the battery to the headphones required that I study JVC's user manual. The process involves having to remove the earpiece covering to get to the battery compartment, which isn't at all obvious.

Be certain your radio is turned off when you initially plug in the earpiece, then after turning on the radio, immediately press the PTT on the earpiece. On most models this initialization syncs the earpiece PTT to the radio. We have experienced a few older model radios which require the radio's PTT to be pressed once, followed by the eapiece's PTT, to initialize, but this is rare. The other possiblity is the earpiece was not made to match the radio you are using it on. The position of the rings on the 2.5mm and 3.5mm jacks can make a difference between models of radios.

Best regards.

Hi Jon,

If this is the earpiece that came with the radio & it states that vox is available for the radio, then Yes would be the answer to your query.

But if you are trying to use a yaesu VC-27 vox earpiece with another Make of radio, say - Icom, then no would be the answer, as each manufacturer, programs each radio/earpiece with vox to work only with their radios.

I hope that clears up your query.

Cheers,
Peter

1) Go into the settings menu, go to FM settings, and make sure the FM Region is set for United States. If you are outside the US, change it to "World"
2) The radio might initially be set for Pause - to test this, turn to a specific radio station that you know you get, and press up on the clickwheel. The "block" icon underneath the radio station should now change to a play arrow, if indeed it was on pause.
