Key Rate
The key rate sets up the sensitivity of the touch keys. There are three different levels of
sensitivity; FAST, MEDIUM and SLOW. The current level of sensitivity is indicated on the
key itself. The FAST setting requires the least amount of time for a key to respond. The
MEDIUM setting requires more time and the SLOW key requires the most time and
makes the touch keys least sensitive.
The key sensitivity is set at factory to Medium
.
Note that this key changes the time required to depress a key for stroke to be recognized.
The pressure required is not affected.

Bolus Volume
The bolus volume can be set from 100 to 1000 ml and can be changed from 100, 200,
400, 500, and 1000 ml each time SETUP BOLUS key is pressed. The current bolus
volume is indicated at the BOLUS status line in the Calibration/Setup screen. The bolus
volume is also displayed within the BOLUS key in the Infuse screen (see Chapter 2 under
Main Infuse screen).

Pressure Limit
The user can set the maximum allowable in-line pressure. The possible setting ranges
from 100 to 300 mm Hg. The current pressure limit value is displayed on the PRESS
LIMIT status line on the Calibration/Set-Up screen. Press and hold the key to change the
limit in increments of 50 mm Hg. During infusion, the system keeps the pressure in the
line under the pressure limit by reducing the infusion rate as the in-line pressure
approaches the pressure limit.
The pressure limit is automatically reset to 300 mm Hg
each time that the system is powered on.
