9V Power Jack – The Crayon can run off of a 9V battery or you can use an
optional 9VDC AC Adapter capable of delivering at least 25mA to the 9V power
jack, such as the Electro-Harmonix 9.6DC-200 power supply. The AC Adapter
must have a center negative plug. The battery may be left in or taken out when
using an AC Adapter. The Crayon has a current draw of 10mA at 9VDC.
- CHANGING THE BATTERY -
To change the 9V battery, remove the four screws on the bottom of the Crayon.
Once the screws are removed, take off the bottom plate to change the battery.
Please do not touch the circuit board while the bottom plate is off or you risk
damaging a component.
