2.4 Filesystem Lock Jumper

The File System Lock Jumper allows you to lock the ﬁlesystem on the GLK24064-25 so that no fonts or

bitmaps can be either written or deleted from the on board memory. This feature is useful in order to protect

data integrity of production units, if protection of other settings is required see Section 12.

To lock the ﬁle system, solder a zero ohm resistor or use a solder jumper on the Filesystem Lock Jumper

pictured in ﬁgure 16 below.
