Escort SOLO S3 uses only a fraction of the power used by conventional corded detectors. Using 2 standard (AA) batteries (included), the SOLO S3 provides months of normal driving protection. A new low-battery warning circuit keeps constant watch on the condition of the batteries, and provides you with both audible and visual alerts before they need to be replaced. A new AutoPower feature (programmable) automatically turns the SOLO S3 off to conserve battery life.
The redesigned Escort SOLO S3 provides long-range warning on all radar bands including conventional and "instant-on" X-band, K-band, and Superwide Ka-band. Patented Digital Signal Processing (DSP) provides the longest warning possible without constant false alarms.
