EPROM

The EPROM (Erasable /Programmable Read Only Memory) contains the software code which controls the function of the OMP-MODL. Updates to add features and/or improve performance are sometimes performed on the OMP-MODL by changing the EPROM to a later version. If desired, contact Omega Engineering, Inc Service/Repair Dept. about performing the upgrade. When a replacement EPROM is received, use the following procedure to remove and replace the EPROMs.

CAUTION

The EPROM chip is especially sensitive to damage from static discharge. Discharge body static before working with the OMP-MODL and EPROM by touching a grounded surface. Call with any questions!
