What happens to the FireFox settings when the power is turned off?
The FireFox units have non-volatile memory that stores settings such as the frequency, amplitude, and menu options. This non-volatile memory does not require any battery backup. The unit will thus power-up with the last frequency and amplitude setting used prior to power-down. Several important settings are stored in the GPS receiver and are backed up by a rechargeable battery that has a life span of typically several days when the unit is powered off. These settings are the position established by the Auto-Survey function and used for position-hold mode, the time offset from GMT, and the receiver operating-mode.
