V Series Operating Instructions xxv
Cautions Introduction
CAUTION: If too much moisture enters the sampling line (i.e., from ambient 
humidity or breathing of unusually humid air), the message “Clearing 
FilterLine” appears in the message area. If the sampling line cannot be 
cleared, the message “FilterLine Blockage” appears in the message 
area. Replace the sampling line once the “FilterLine Blockage” message 
appears. 
CAUTION: Microstream

 sampling lines are designed for single patient use, 
and are not to be reprocessed. Do not attempt to clean, disinfect, 
sterilize or flush any part of the sampling line as this can cause damage 
to the monitor. 
CAUTION: Before use, carefully read the Microstream

Directions for Use. 
CAUTION: Only use Microstream

 sampling lines to ensure the monitor 
functions properly. 
CAUTION: Do not use if the BIS sensor is dry. To avoid dry out, do not open pack 
until ready for use. Due to intimate skin contact, reuse may pose risk of 
infection. If skin rash or other unusual symptoms develop, stop use and 
remove. Limited to short-term use (maximum of 24 hours). Do not cut 
sensor components, as this can result in improper operation.
CAUTION: The VDI module enables the V 12/V 21 to display and store data 
received from another specialized medical device. The V 12/V 21 can be 
set to provide alarms on received data, but the connected medical 
device should be regarded as the primary monitor for the parameter it 
is monitoring. For patient safety, do not turn off the alarm systems of 
connected devices. 
CAUTION: The VDI serial port connector is exclusively for connection to 
equipment. The serial port connector should not contact the patient 
while the VDI module is in an operational system. 
Always keep both ends of a serial cable connected to the VDI module 
and the associated equipment while the VDI module is plugged into an 
operational system and keep the VDI module out of patient contact. 
It may be most convenient to use the VDI module configured in a 
stationary external module rack.
CAUTION: When powering off the unit, do not continue to hold the power button 
down after the triple-beep signal is heard. Holding the power button 
down for more than three (3) seconds initiates a hard shutdown of the 
monitor which may cause unexpected and potentially harmful effects 
to the monitor database.
CAUTION: The AC receptacle (or mains plug) is used to disconnect the medical 
device. Refer to "Back View" on page 1-10 to see where the AC 
receptacle is located on the device.
