Step 5 - Updating the Communication Plug Firmware
If you received communication plug PROM(s) with your order, you
need to update your PROM(s) to complete the flash upgrade.
1. Make sure you have already removed the battery cover and
disconnected the battery and disconnected any cables attached to
the processor.
!
ATTENTION: Printed circuit board components can
be damaged during routine handling and installation.
Follow these precautions to reduce static electricity
discharges before you upgrade the processor firmware.
• Handle the printed circuit board by the case or
carrier without touching the pins or the edge
connector.
• Use a static-free workstation.
• Connect the static-free workstation to ground
through a minimum 200K ohm resistance.
• Wear a grounded, conductive wrist strap with a
minimum 200K ohm resistance.
• Ground all tools before you begin to upgrade the
firmware.
• Control the relative humidity of the installation
area. Ideal conditions are 40-60% relative
humidity.
