* From time to time, we might experience trigger bit issues (FT bits: 24, 25, 26, 27). Bit 26 might not trigger the alarm but when this issue happens it will count abnormally high. For the time being, shift leaders can try to do the sequence of End->Cancel->Reset, roc_reboot adcft1 (and adcft2, adcft3), make sure the ROCs are connected, then Download->Prestart->Go. If this does not work, repeat the sequence and add "Configure" in front of "Download". If the trig issue persists, continue to take production data without fixing it -- please make sure you log this infor in the RCDB "Comment" field. | * From time to time, we might experience trigger bit issues (FT bits: 24, 25, 26, 27).

- Note, all non-JLab numbers must be dialed with an area code. When calling from a counting-house landline, dial "9" first.
- To call JLab phones from outside the lab, all 4-digit numbers must be preceded by 757-269
