35Charge RegulatorRechargeable Nickel Metal Hydride (NiMH) batteries require a particular power delivery cyclefor optimum charging and battery life. An unregulated power supply can provide a NiMHbattery pack with charge, but without proper regulation the battery can become damagedfrom over-charging or over-heating. Please use the supplied charge regulator and AC plugpack to maintain battery condition.Depending on the options ordered, the charge regulator may be supplied in a smallweatherproof casing or packaged in a wall-mountable box containing other optionalcomponents. In either case, a single LED on the charge regulator provides the status of thecharging cycle and displays any errors. Use the information below to decode the status ofthe charge regulator and the battery condition.LED Patterns (routine)Traffic light (Red-Orange-Green) System reset.
