2. WARNINGS
Read these instructions carefully before using the thermometer
2.1 Precautions
To avoid reading anomalies, use VisioFocus PRO according to this user manual.
Use VisioFocus PRO in a draft-free room, at a steady temperature between 16 and
40°C (60.8 and 104°F).
If the thermometer was stored in another room (or even in a drawer, etc.), before
using it, run the manual calibration procedure (MQCS – par. #8). No matter if it is
set in “NURS” or “DOCT”.
Do not take a temperature reading in the following situations:
• if the subject is sitting in a draft or has come from another room that was ventilated
or at a different temperature than the room where the thermometer is used;
• if, in the minutes before reading, the subject has:
- been walking, running or exercising;
- been wearing a cap, hat or scarf;
- been cool sponged on the forehead;
- been exposed to agents that could alter forehead temperature, e.g. shower,
shampoo, hair-drier, direct sunlight, fireplace heat, cold compresses therapies, air
conditioner flow etc.; even touching the forehead can alter the temperature.
In all the above cases, interrupt the exposition of the subject to these agents and wait
a few minutes for the forehead temperature to stabilize.
Changing the reading point will lead to different results. Therefore, remember,
always
aim the projection on the same spot, precisely at the center of the
forehead
(midway between the top of the nose and the hairline) and keep the
thermometer perpendicular to the forehead. Do not take measurements on areas
other than the centre of the forehead, except for the case at #4.2.
The temperature reading is taken in the area where the temperature is projected.
Make certain that a 1 cm (0,4 in) area is free all the way around the temperature
projection area: it is of major importance to make sure that this area does not include
eyebrows, hair or clothing. If necessary, brush away any hair from the forehead but
remember, this must be done a couple of minutes beforehand or the temperature
reading will be higher than the actual body temperature.
When taking a temperature reading, please note that in the presence of oils, make-up
or an oxygen mask, and in the case of elderly, the temperature detected may be
lower than the actual body temperature.
The forehead temperature reading can be affected by profuse sweating, superficial
wounds or head injuries.
Do not use the thermometer on a sweaty forehead
, since the temperature
reading will be unreliable.
In the cases at #7, #8, #9, take the temperature reading on the alternative area
(read the par. #4.2.).
The gilt waveguide (figure 1) is the most delicate part of the thermometer. It is
composed of a gold-plated concave mirror that must be kept clean, crystal clear and
intact. Any damage, dust or dirt will alter the temperature reading.
