[. . . ] Do not let children operate any transmitter-equipped radio equipment without proper supervision. Avoid exposing the Lithium Ion battery, attached or unattached to the radio, in direct sunshine, heated cars, or in areas with temperatures below -20°C (-4°F) or above +60°C (+140° F). Exposing the chemicals contained within the battery pack to temperatures above +60°C (+140°F) may cause the battery to rupture, fail or reduce performance.

Think of the squelch control as a frequency gate which controls access to weak or strong signals depending on its setting. To listen to a weak or distant station, turn the knob counterclockwise. If reception is poor, turn it clockwise to cut out weak transmissions. If the squelch control is adjusted so you continually hear a hissing sound, the unit will not scan properly. To turn Off the unit, turn the Volume / Power knob counterclockwise until it clicks. One-touch Channel 16/9 Example: While you are monitoring channel 20, you want to check channel 16 or channel 9. While in Triple Watch mode, you can change the currently selected channel using the L or M button. A momentary press of the 16/9 button interrupts Triple Watch mode and remains on 16, or on channel 9 if you press once more. Programming a Channel into Memory Before using the scanning feature, you have to program channels into memory. Scanning starts from the lowest to highest channel and stops when it finds an active channel. It remains on that channel until the transmission ends, then resumes scanning after a 3 second delay period. When in the scan mode, the unit automatically activates the Triple Watch feature. Press the 1/5W button to make the change, then the "5W" or the "1W" indicator on the display changes accordingly. [. . . ] Don't install your transceiver without having read this instructions manual.
