CP185 has intermittent static, when pressing button to talk screen displays "channel busy" and battery will not keep a charge.
Could be one of several issues. A few which come to mind are:
1) You have a bad or poorly charged battery. Static is a sign of a bad or poorly charged battery. Try swapping a battery from another radio, with a known good battery and see if the problem is solve. If this resolves the issue check your battery and charger. Tip: Clean all charge contacts with a pencil eraser to ensure good charging. Also, check your 3- or 4-digit date code on the battery. If more than 2 years old, replace the battery. (4-digit date code example 1303 would be 2013 the 3rd week; on 3-digit date codes the first number is the year and the next two the week of the year.)
2) You are trying to use the radio in an area where you are experiences high RF on your frequency. This is the "busy"... someone/something is on or near your radio's frequency and interfering with transmission. Try your radio at a different location and see if the problem persists.
3) Another radio in the workgroup is stuck in transmit, causing static, and the channel busy. Turn off other radios, one at a time, and see if the problem still exists.
4) Or if you have an audio device plugged into the radio, try unplugging it and see if the problem stops. FYI: All audio devices must be plugged or unplugged with the radio shut off. If you plug one in with the radio turned on, you can experience some unexpected intermittent issues.
If none of these seem to be the problem, your radio is likely in need of repair.
