On the top or side should be a small rubber flap. Open it and your charging plug should under it.
SOURCE: GMRS/FRS static, call button not working, which channel?
Are the radios new or old? Are they likely to be broken?
We need more info to help!!

This is more for "mshtexas" than the OP but I'm sure there may be others out there wondering the same thing. The power cord that comes with this unit has a 9.0v output at 200mA with the center pin being positive

Hmmmm maybe your keypad is broke or your radio is locked
SOURCE: The battery is fully charged
Your batteries are either no good, or not charged. When you press the PTT button it takes more energy than being in standby mode. If you have a battery problem it will fail quickly when the PTT is pressed.
Rechargeable batteries last approx. 18-24 months. Check your battery for a 3-digit date code. It is usually a 3 digit number followed by a couple of letters. The numbers tell the date of manufacture. The first number is the year, followed by the week of the year. 025 would be 2010 the 25th week. (or if very old it could be 2000 the 25th week.)
If you feel age is not a problem, you might check your charger(s) to see they are fully powered, and clear of debris on the contacts (and the radio contacts as well). Clean with a pencil eraser if needed.
A few tips: Be certain when placing your radios on the charge they are turned off. Check your wall outlet to be certain it doesn't get shut off with a light switch. Expect to replace your batteries every 2-3 years.
Best regards.
