Filesystem Lock Jumper

The Filesystem Lock Jumper allows you to lock the filesystem on the GLT240128 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 filesystem, solder a zero ohm resistor or use a solder jumper pictured in Figure 20 below.
