EMERGENCY CHARGE MODE

The system has an Emergency Charge Mode (ECM) if its re c h a rgeable battery pack goes completely ‘dead’ or too low in charge to run the normal Charge Function. Pull out MCK and turn it to roughly the middle position. It’s OK if the lights don’t come on, ECM will fix that. Put all the other controls in roughly the middle position, and use a short patch cord (1 foot or less) to lower resistance. Plug your patch cable into the charg e r, into the guitar, and connect your power supply to the charger and power it up. The charger will soon blink red (seeking a guitar). The charger will recognize the problem and after 30 seconds will blink yellow. It will soon provide enough charge to activate and switch to normal charging mode automatically. The length of time it takes to re-activate the normal charging mode can be from a few seconds to a minute or more.

AUTOMATIC SWITCH OFF MODE

If the MCK is left in the ‘on’ position for more than 120 seconds, the system enters Switch Off Mode, indicated by a flashing green light. After 30 minutes the system turns into Standby Mode, indicated by a very slow flashing yellow light. You can re-activate the system in either status by turning the MCK.
