3.3 Lithium battery maintenance
The SDR2-USB's real-time clock uses a small lithium battery to maintain time when external power is unavailable. The life of this battery should exceed 5 years.
If you find your SDR2-USB is not keeping time correctly when power is lost, you may need to replace the battery. If necessary, replace the battery with a Panasonic CR2032, or equivalent, making sure the positive (+) face is in contact with the battery clip. After replacing the battery, be sure to reset the SDR2-USB’s time and date.
3.4 Resetting to factory defaults
The SDR2-USB can be reset to factory defaults by removing the USB storage device, holding the record button, and connecting power. Once power is connected, the record button must be held for 5 seconds until the flashing pattern is displayed on the front panel LEDs.
Resetting to factory defaults overrides all settings that have been changed via the setup file.
