DRAFT Appendix B P/N 7010-0752 1 Specifications This TPS product is a 50-channel GPS receiver integrated with an internal computer and Windows Mobile6.0 operating system with touch screen, a digital camera, a Bluetooth® wireless technology module, celler module(option),an electronic compass, and an SD card slot. The portable design and product integration allows this device to be a fully-functional, productive tool at any job. Performance specifications assume a minimum of 6 GPS satellites above 15 degrees in elevation and adherence to the procedures recommended in this manual. In areas of high multipath, during periods of large PDOP, and during periods of increased ionospheric activity, performance may degrade. Use robust checking procedures in areas of extreme multipath or under dense foliage.
