The Cobra microTALK FRS 120 is a 14-channel 2-way radio designed for short-range communication. To get started, install three AA alkaline batteries, turn the unit on using the volume switch, and ensure all radios in your group are tuned to the same channel. Use the Talk button to communicate and the Call button to alert others.
Product Overview
The radio features a backlit LCD display, a removable SNAP front panel for customization, and a microphone/speaker jack for hands-free accessories. Key controls include the On/Off Volume switch, Channel Select buttons, Talk button, Call button, and the Light/Max Range button.
Getting Started

- Pull the lock tab down to remove the battery cover on the back of the unit.
- Insert three AA alkaline batteries, ensuring they are positioned according to the polarity markings.
- Replace the battery cover.
Operation
