The HX3 lacks a display or standard keyboard. Instead, the high-impact plastic case features three status LEDs, plus four large keys with easily-distinguished shapes. Three keys, plus one modifier key, allow six different choices that can be mapped to standard keyboard equivalents. Other input is via the unit's built-in microphone or headset interface. According to LXE, the unit is certified to work with a variety of third-party voice-recognition programs.
An included software development kit supports application programming interfaces (APIs) from both LXE and Microsoft. The company says the HX3 is also compatible with voice-over-IP (VoIP) software, and provides an integral push-to-talk feature.
LXE says its "ToughTalk" technology features advanced audio circuitry and noise-canceling techniques. With the HX3, users can run voice logistics applications and still have the flexibility to scan barcodes when necessary, the company says.
Accordingly, the unit offers an interface for barcode ring-scanners. An SR laser ring offers a 45-inch scan distance, while a 2D imager ring offers a 21-inch scan distance. Both feature illumination provided by a white LED flash.
The company offers a variety of accessories, including a standard battery said to last for a 12-hour shift, and an extended battery said to last 24 hours. Batteries are remotely tethered, for greater operator comfort, with a choice of cable lengths. Finally, LXE lists a six-bay battery charger, and a two-bay charger that also acts as a desktop cradle for the device.
