Exceeding the maximum intensity selection
The maximum selectable intensity is 22 mW/cm². If the intensity knob
(6.13) is set to a value, which the radiant warmer is unable to reach, the
maximum selectable value is indicated in LED (6.12a) by a permanent
spot. The (unreachable) selected value is indicated in LED (6.12a) by a
flashing spot. In that case reduce the intensity selection to the maximum
possible intensity by turning knob (6.13) anti-clockwise.
In that case the LED spot for the selected value and the LED spot for 10 mW/cm² in display (6.12a) flash
alternately and a short alarm tone sounds every 2 seconds. Check the patient's temperature and push
button (6.4). Now the alarm is reset and the selected intensity is emitted for further 15 minutes. The warning
lamp (6.10) lights permanently and indicates that the safety function (>10 mW/cm²) is activated.
The actual intensity display (6.12b) refers to the surface of the bassinet. The radiation intensity
reaching the patient's skin is approx. 4 mW/cm² higher than the displayed value because the
distance of the radiant warmer to the patient surface is approx. 10 cm lower than to the surface of
the bassinet.
If during long-term care the patient's demand of heat has stabilized, and if this is above a value of
10 mW/cm², the 15-minutes-alarm and automatic heating capacity reduction can be deactivated by a
conscious action. This, however, does not remove the obligation of checking the patient's temperature in
regular intervals. If the patient's temperature is monitored, the automatic 15-minutes-alarm and the heating
capacity reduction can also be deactivated.
In order to deactivate the 15-minutes-alarm and the automatic heating capacity reduction, push button (6.4)
for approx. 3 seconds until two short tones sound.
When the 15-minutes-alarm and the automatic intensity reduction are deactivated, in case of an intensity
selection above 10 mW/cm² the warning lamp (6.10) flashes permanently.
When the 15-minutes-alarm with automatic intensity reduction shall be reactivated, push button (6.4) for
approx. 3 seconds until one short tone sounds. When in case of an intensity selection > 10 mW/cm² the
15-minutes-alarm and the automatic heating capacity reduction are activated, the pilot lamp (6.10) lights
permanently.
Whenever the radiant warmer is switched-on after non-operation, the 15-minutes alarm and the automatic
heating capacity reduction are activated.
