While working on radios is fun, it's important to be safe.  Here are some good rules to follow: 

• Electrical shock can hurt or kill - make sure the power is disconnected before working.
• Even with the power off, some parts inside the radio can hold a dangerous charge. If you don't know what you are doing, get help.
• Radio Frequency (RF) can burn - keep antennas out of reach .
• Strong RF radiation can be unhealthy - Don't use a radio when it is not completely assembled. The case keeps the RF radiation where it should be.
• Make sure antennas can't touch any power lines or you could be electrocuted when using the radio.
• Lightning can hit your antenna and travel down your lines to the radio. Make sure your antenna and radio are grounded to a good earth ground.
• Be careful working on towers and roofs so you don't fall or drop something onto someone on the ground.
