Alternate use for 2.5 mm Nutdriver for iPhone

我的问题

At times a JCM UBA will fail to disengage the transport locking mechanism on a bill stacker/validation error

我的修理方法

2.5 mm Nutdriver for iPhone can be used to manually unlock the transport cover by inserting the nutdriver into the access hole on the right side of the validator unit and turning counterclockwise two and a half turns.

我的建议

Having your own tools is great.
