Volume programming I use Motorola GM 340 Radio's. When I turn the volume knob down it does not turn the volume off completely. Is this possible. I have looked at the Volume programming, but did not find where and if this is possible. Regards Martin (South Africa)

It sounds from your description there is a fault in the audio section electronics rather than with the button.

Unfortunately, your volume potentiometer (the part behind your volume knob, which connects to the component board, has gone bad. This can happen from turning the knob too far past full volume or even sometimes when turning it off. The part to repair this has never been offered as a replacement part. Your only solution is to remove the battery to turn the unit off.

Best regards.

The on/off/volume potentiometer is a common failure part on most radios, including the XTN. The only solution is to have the radio repaired. Typically this style unit can be repaired for $69 flat rate.

Sidenote: On the XTN it is best, when turning on the radio, to turn the knob to at least 50% volume before turning it back to your desired setting. This helps with the initialization of the radio. Also, it is best not to run this style of radio at full volume, as it can cause other receive issues down the line.

Best regards.

This is an easy fix with a can of volume knob cleaner i think its called. You should be able to get it at radio shack. You just spray it into the volume knob and let it dry. The instructions are on the can.

You have posted this question under the heading for the Motorola SP50 battery pack. I will assume you are referring to the SP50 radio. Check your radio's grill to be certain it is clear of debris. Was this radio previously working correctly? If so, that eliminates a programming or narrowband-wideband issue. If the radio is new to the group, you might check the programming and verify if the others in your workgroup are narrow or wideband. Two common failure parts which could effect the sound coming from the speaker would be the volume potentiometer (the part your volume knob sets on top of), and the speaker itself. It is possible your radio may need repair. In most cases this style radio is repairable for approx. $85 flat rate.

first of all if you live in a cold climate I never turn the radio on until the car warms up if you can remove the knob on the radio spray a light amount of WD 40 and then put the knob back on and turn it back and forth and if you have pop on your hand or water also dry your hands off before touching the radio the lights and the radio will last a lot longer also and also before leaving the car always remember to turn the radio off it will be alot easier on your battery as well

Check the grill in front of the speaker area for debris or plugged holes. Check the transmitting radio for debris blocking the mic hole. When turning volume up on the radio, do not max out the volume knob, back it off slightly for best sound. If these do not help, your radio is probably malfunctioning and needs replaced.

Hands-Free Use With Accessories (VOX)
You can transmit hands-free with the use of optional accessories. Once
VOX is turned on, the radio detects your voice and transmits when you
speak.
1. Turn the radio off and plug the VOX accessory into the accessory
port.
2. Turn the radio on. VOX shows on the display.
3. Adjust the volume appropriately by rotating the volume knob . Lower the volume
before placing the accessory on your head or in your ear.
4. To turn off, simply remove accessory.
Note: There is a short delay between the time you start talking and
when the radio transmits. There is a short delay before the
transmission is completed.

You must be using a VOX capable accessory. Generally this is an accessory without an in-line PTT.

When I turn on my radio, the volume is on and o.k. but when I try to turn it higher or lower the volume is lost completely. Any comments?
