EMERGENCY CHARGE MODE

The system now has an Emergency Charge Mode (ECM) if its internal rechargeable battery goes completely dead or too low in charge to run the normal Charge Function. Put MCK in the C position. Plug your patch cable into the charging device and connect and plug in the transformer. The charger will blink with a red LED (seeking a Guitar). When the LED begins to blink yellow the charger can be connected to the guitar. The charger will provide enough charge to make it possible to start the regular charging mode. The condition of time to reanimate the charging mode is related to the state of battery-level (approximately 10 seconds up to a couple of minutes). After ECM is completed, the system runs in normal charge mode.

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.

Note: It is recommended not to store the guitar with the MCK out, as this will fully drain the battery eventually and Emergency Charge Mode must be employed.
