CLEARING STANDARD MEMORY & FIRMWARE
1. To clear the I/O module's standard memory and firmware,
power down the VRC unit and remove the lid. Find the JP9
jumper. The I/O board is on the bottom level of the chassis.
2. Engage the JP9 jumper. This is done by pushing the jumper
onto both pins to complete the circuit (refer to the drawing on
the next page).
To clear the memory and
firmware for the voice
interface module, follow
the same procedure but use the
JP1 jumper on the voice board
instead of JP9 on the I/O.
