Reset Procedures No Output Reset Procedure
The Stinger Medical DC-to-DC circuit boards have been upgraded to self-resetting
polyfuses. If a situation occurs that could cause harm to a circuit, these fuses will trip and
protect the circuit from damage. The result of a tripped fuse is no output. Many reasons
could cause a fuse to trip. If a fuse is reset and the system continues to have a problem,
discontinue use of the system and contact the Stinger Medical C.A.R.E. department.
Below is an order of operation for resetting these fuses:
1 Remove all devices that are connected to the power system’s outputs.
2 Wait approximately 30-45 seconds after devices have been removed.
3 Insure that all devices are switched off, and then reconnect those devices.
4 Power on connected devices one at a time.
5 If fuse does not reset, repeat Steps 1-4 until fuse is reset.
If you continue to experience problems with the power system, discontinue use of the
system and contact the Stinger Medical C.A.R.E. department.
Charger Timed-out Reset Procedure Note:
The following procedure is designed for use only with the MC2 Power System Series
26 Amp-Hour Unit.
1 Remove all devices that are connected to the power system’s outputs.
2 Unplug AC power source.
