End Station VEAs "swept" for Observing
Ed, Fil
Both end stations were swept as per LVEASweepChecklist. Checklist will be slightly edited for some ambiguities:
Phones unplugged & batteries pulled from handsets (Phone locations here)
includes both electrical connection(transmitter and other base-station functions) as well as the actual telephone connection from the block as to prevent ringing.
Power down the intercom via blue box in Airhandler room
these are actually small BLACK boxes marked VALCOM. They are plugged/screwed into a wall socket and must be laid on some support as to not let them hang on their wires.

the Valcom system is mentioned by name in the LVEA sweep and just hadn't been carried to the End VEA sweep check until now.
