Normal operation
When the self test has been successfully performed, the warming will automatically commence. Make sure
that the correct mattress type is selected (H2O or GEL). If an incorrect mattress type is chosen, the
heating performance will either be reduced, or a Heating Pad alarm will be activated after some time of
operation. Adjust the set temperature as required. The running conditions are showed by the colours of the
icons.
Temperature settings
When temperature settings
below 35°C or above 37°C
are to be selected, the unit
will alert the operator by
prompting for confirmation
(
press LEFT or/RIGHT key
and OK for confirmation
)
Key lock function
After 30 sec of operation, the key lock function will activate (if selected ON in the set up menu) and the
key lock symbol will be displayed in the bottom left corner of the display. This is a safety feature
implemented to prevent involuntary changes of any operation setting. In order to unlock the keyboard and
change any setting, or to turn the unit off, please press one of the two key lock buttons once, and within 5
seconds press the other key lock button. The key symbol in the bottom left corner of the display will then
disappear and the unit will accept any command.
Temperature Monitor
The temperature monitor function will automatically be activated as
soon as an YSI400 compatible (skin) temperature sensor is fitted to the
6,3 mm phono type (T) front intake. The temperature of the sensor will
be displayed in the upper left corner of the display.
BW3-099 YSI Skin Temperature Sensor
Place the temperature sensor according to your standard routines.
It is possible to set high- and low temperature alarm levels. The high level default setting is 42 °C and the
low setting is OFF (--- = low temp alert not activated). If the sensor-temperature exceeds the upper temp
limit, the thermometer icon flashes red, the alarm LED flashes yellow and an acoustic signal is emitted. If
the sensor-temperature falls below the set low temp limit, the thermometer icon will flash blue, the alarm
LED flash yellow and an acoustic signal is emitted. The acoustic alarm may be silenced for 2 minutes by
pressing the Alarm key. During the time of silenced alarm, the yellow alarm LED will be on.
Note
: If the temperature sensor initially is colder than the low alarm level, the thermometer icon will
display blue, but the alarm will not be activated (the alarm will only trigger when the YSI temperature is
falling, from a reading higher than the LOW alarm limit.
