4-12 User Manual
When the channel has been locked, the software detects that a needle has been connected
and the channel opens for testing. A dark gray channel button indicates a channel with needles
connected. If the needle contains a memory chip, the Visual-ICE System automatically detects
the type of needle being used, the lot number, and the expiration date of the product. If the
system detects that the expiration date has passed, a message appears and gas ow to that
channel is disabled.

• Place the needles, individually or in groups, in the basin such that the full length of the needle
shaft is submerged in the sterile water or saline.
