15% capacity. At this point, the unit should be recharged as soon as possible. Note, depending upon the
amount of usage, the SM will continue to function for approximately one full normal business day when the first
low battery beep/LED occurs.
2. To recharge the unit, remove the protective rubber plug from the charging port on the SM cable. Plug the
5.5mm connector of the Stone Mountain approved charger into the cable charging port. The SM LED will flash
red/green during charging when the SM is powered on. Full charge takes between 5 to 6 hours assuming a
completely discharged battery. Replace the protective rubber plug after charging is complete.
3. The SM can also be charged in optional TruDockTM single bay, vehicle mount and gang chargers.
