ALARM SOUNDING
With the alarm enabled (a bell logo on current screen situated on the top left),
the unit will sound an alarm when the temperature being displayed is outside
the alarm limits that have been set for that display mode (equal to or lower
than the low alarm set point, or equal to or greater than the high alarm set
point).
If the alarm is sounding based on the low alarm limit e.g. 2
0
C, “LO” will flash
on the display.
If the alarm is sounding based on the high alarm limit e.g. 8
0
C, “HI” will flash
on the display.
The unit will continue to alarm and flash the corresponding “LO” or “HI” until
the temperature being displayed is within the alarm limits. Once the
temperature being displayed is within the alarm limits, the alarm will stop
sounding and the corresponding “LO” or “HI” will no longer flash.
To silence an alarm manually, press either the minimum or maximum button
once. When manually silenced, the corresponding “LO” or “HI” will continue to
flash on the display until the temperature is within the alarm limits. For
temperatures out with set limits see guidance on page 1, section 6.
To check the alarm settings press the MODE button once. The alarm settings
must be set at 2
0
C LOW and 8
0
C HI. Please ensure the MODE button is
pressed once again to return to normal display settings.
RESET BUTTON
The RESET button located on the back of the unit must not be pressed. If
there are any problems with the thermometer please contact Vaccine
Services staff who will advise.
ON/OFF BUTTON
The ON/OFF button located on the back of the unit may be used to turn the
unit off when the thermometer is not being used. The minimum/ maximum
memory and alarm limits are not cleared when the unit is turned off. To turn
the unit off,
press the ON/OFF button. Each successive press of the ON/OFF button will
turn the unit on or off.
No alarms will sound and no minimum/maximum memory will be
recorded when the unit is off.
MAGNET ATTACHEMENT
Vaccine Services advise that the magnet be attached to the back of the unit
and placed on top or on the side of the fridge. There is no need for the
thermometer to be moved whilst recording the temperature as all
temperatures are displayed on the front. This also avoids inadvertently
pressing any of the blue settings on the back.
