The only definitive data I have on the internals is the owner's manual, that on Page 10 states that Backup power is provided by a "3V Lithium-Ion rechargeable battery". Additionally, on Page 26, it says "Commands can be issued to the HI-204III to change the settings of the receiver. *The new settings will remain effective on next power-on as long as the on-board rechargeable backup battery is not discharged. After the backup battery is discharged, factory preset default settings will be used*."
Factory defaults are as follows: Datum: 000 (WGS-84) NMEA Commands: GGA ON (1 sec), GLL OFF, GSA ON (5 sec), GSV ON (5 sec), RMC ON (1 sec), VTG ON (1 sec) and Checksum ON Baud Rate: 4800 Elevation Mask: 5° DOP Mask: DOP Select: Auto, GDOP: 10, PDOP: 10, HDOP: 10. Receiver Operating Mode: Normal Mode (without 1PPS) On Tuesday, August 29, 2017 at 1:41:51 PM UTC-7, Terry S wrote: > I believe the label is still on my puck, I will look this evening. > > Lithium batteries are finicky little devices.
