2.3.3.3 Changing communication settings in the SEP
CAUTION
Many components within the SEP are susceptible to damage due to electrostatic
discharge. You must take precautions against such damage: These precautions
include the use of a grounded conductive mat and wrist-strap. TSS will not accept
responsibility for any damage caused by failure to take such precautionary
measures.
To disassemble and reassemble the SEP you will need the following tools and facilities:
❐
A clean anti-static work area
❐
A 3mm hexagonal key
❐
A 2.5mm hexagonal key
Remove the ‘Power/Comms’ end-cap:
1. Use the 3mm hexagonal key to release and remove the four M4 × 12mm A4 stainless-steel
screws that secure the end-cap to the housing.
2. Use the 2.5mm hexagonal key to remove the two button head screws from their threaded
holes near the edge of the end-cap.
3. Insert two of the M4 × 12mm screws into the holes vacated by the button head screws and
tighten them by hand until you feel resistance.
4. Use the 3mm hexagonal key to tighten the two M4 × 12mm screws alternately so that they lift
the end-cap away from the SEP housing.
