WARNING

Although the highest DC voltage in Mobile Two-Way Radio Equipment is supplied by the vehicle battery, high currents
may be d rawn under short c ir cuit co nditions. Th ese c urrents c an p ossibly h eat o bjects such as t ools, ri ngs, wa tchbands,
etc., enough to caus e burns. B e careful when working near energized ci rcuits.

High-level RF energy in the Transmitter Power Amplifier assembly can cause burns upon contact. Keep away from
these circuits w h en the t ra nsmitter is energize d!
