Batteries are not charged in the unit. If
external power is applied, the SF-3040 battery
LEDs indicate the status of the batteries, not
the status of the external power source.
Battery Charging
The SF-3040 battery packs are shipped in a
partially charged state. Complete one full
charge cycle (LED changes from red to green)
before battery use.
All new batteries must be charged for a
minimum of 12 hours prior to use, regardless
of the LED indicator on the charger.Charge
the batteries for 12-hours after each use to
ensure longest possible usage each day
If the battery packs are left charging for
longer than 5 days, the charging indicator
LEDs will shut off. If this occurs, place the
battery packs in the SF-3040 GNSS
receiver and power on for 10 to15 minutes
to slightly discharge the batteries.
SF-3040 Battery Installation
The battery chambers are located on the side of the
SF-3040 receiver. There are two locking clips on the
outside edge of each battery chamber to hold the
battery packs in place.
