Thank you for purchasing the Cobra HH 37 ST handheld CB. Properly used,this Cobra product will give you many years of reliable service. SoundTrackerTM “Cuts noise coming in...strengthens signals going out.” This Patent pending technology dramatically improves transmission and reception of CB signals. The revolutionary SoundTrackerTM System recon- figures the transmission signal which allows it to be transferred more efficiently through cluttered airwaves. At the same time,it significantly reduces the amount of static on all incoming CB signals. The end result is a cleaner,clearer sounding reception of signals and a more powerful transmission which dramatically improves CB communications.

The SoundTrackerTM System While previous systems only “blanket out”or limit noise in higher sound frequencies,the revolution- ary new SoundTrackerTM System actually reduces noise while leaving the signal intact in the recep- tion mode.In the transmission mode,it actually strengthens the signal,providing you with a significant reduction in noise on reception and transmission. Sound clarity is measured by the ratio of the signal level to the noise level. The higher the signal-to-noise ratio, the better the sound. How SoundTrackerTM Works On Reception - “Cuts noise coming in” With a normal CB,distant signals fall below the squelch level and are unintelligible. With a SoundTrackerTM CB,the noise level is cut up to 90%,which increases the signal-to-noise ratio and dramatically improves signal clarity. This also allows you to significantly reduce the squelch level,which greatly expands your listening range. On Transmission - “Strengthens signals going out” A SoundTrackerTM CB strengthens the transmit signal by more effectively using the available RF power output of the CB. The result is improved transmission signal clarity and an expanded transmission range.Operation Operation1110 Activating SoundTracker™Activating SoundTrackerTM Note SoundTracker™ gives you clearer,cleaner reception to improve CB communications while on the air.Pushand releasethe ST key.1 The SoundTracker™ LED will illuminate red.2Note This engages the SoundTracker™ system and reduces the noise level.37st manual layout.5 10/1/98 9:56 AM Page 16
