We talked to the housekeepers to see if they noticed an increase in static within the last month, than one of the housekeepers told us how she noticed the static when they change the sheets. We found that they change the bedding, than dust, and check the phone. Some of the people check the phone first, since the sets go to sleep, so they have to touch the screen to see if they are working, I have a feeling that they may be discharging thru the screen. We are waiting to here from the repair facility if our suspicions are right.
For now, we have them touching the handset or base first, before they touch the screen.
They only use the i2007's in the rooms, the offices all use the 1100 series. We are going to look into whether the 1165e might work better in the rooms.
The Comm Closets are all on filtered power, and all racks are grounded. They really planned this place right.
