9.1. CONNECTING CABLES

The catheter extension cable and the pressure and tempera-
ture cables are fitted with guide pins, to facilitate proper con-
nections.
To attach any of these cables:
1. Align the arrows on the connector tip with the mark-
er [25] of the inlet (or outlet), on the Monitor right panel.
2. Push the connector in. It should enter easily without
forcing.
To disconnect, slide the connector envelope away from the
inlet (or outlet), and pull the connector from the inlet (or out-
let).

9.2. POWERING ON THE MONITOR

WARNING
The Monitor performs a self-test when powering on.
During this self-test, the battery indicator and power in-
dicator lights glow and the speaker emits 3 beeps. If the
indicator lights do not glow, or if the speaker does not
emit 3 beeps, disconnect the Monitor and contact So-
physa Customer Service at contact@sophysa.com, or
contact your local distributor.
Power on the Monitor as follows:
1. Affix the Monitor to a pole or rail.
2. Connect the power cable to the power inlet of the Moni-
tor.
3. Connect the power cable to mains power.
4. Press the power button.
The battery indicator (orange) and the power indicator
(green) lights on the front panel of the Monitor glow simulta-
neously for 4 seconds. The Monitor then emits a series of
3 beeps, and the touch screen displays a message instruct-
ing the user to connect the Catheter.
Auto-calibration of the Screen
The touch screen auto-calibrates when the Monitor powers
on. Do not touch the screen during this auto-calibration.

9.3. ZEROING THE CATHETER

Zeroing the Catheter involves calibrating the catheter in rela-
tion to atmospheric pressure.
WARNING
Perform the zeroing procedure on each new Catheter,
before implanting it in the patient.
Page 20 of 174
CAUTION
Observe aseptic technique throughout the entire zero-
ing procedure.
NOTICE
Do not allow the catheter extension cable connector to
come into contact with liquid.
NOTE
The intracranial temperature sensor is calibrated in the
factory. Therefore, the temperature setting does not
need prior zeroing.
Consult the Instructions for Use supplied with the Catheter
kit. These instructions contain additional information on the
precautions to be taken with the Catheter.
9.3.1. Prerequisites
– Power on the Monitor.
– Connect the catheter extension cable to the Monitor.
A message inviting you to connect the Catheter displays
on the Monitor screen.
9.3.2. Procedure
1. Unpack the Catheter (sterile) within the sterile field.
2. Prepare a shallow cup of sterile saline solution (less than
5 mm).
CAUTION
Using a deep receptacle could lead to hydrostatic
pressure greater than atmospheric zero, which
would then lead to an erroneous reference zero.
3. Observing aseptic technique, connect the catheter ex-
tension cable (non-sterile) to the Catheter, aligning the
blue arrow on the Catheter dongle [26] with the blue ar-
row on the catheter extension cable connector [27].
The Catheter dongle must be completely inserted into
the catheter extension cable connector. A blue line on
the Catheter dongle indicates the point of complete in-
sertion.
4. Within the sterile field, immerse the sensor (metal tip) of
the Catheter [28] in the cup of sterile saline solution [29],
without touching the cup.
