Hints and Tips
Battery test
It is strongly recommended that you regularly test the unit with cold water to ensure
that there is sufficient battery capacity for the device to operate properly, therefore
eliminating any potential issues with boiling water over-flowing due to a malfunction
with the LLI.
The battery can be tested by opening and then closing the battery drawer and waiting
for the confirmation three beeps to sound (with vibration for the DK127) which tells you
that the battery is OK.
Operational test
After you have tested the battery you may wish to test that the unit will operate
correctly to detect the liquids. This can be simply achieved in one of two ways. Moisten
one of your fingers and hold it across the top of all three probes. This will produce a
continuous tone from the unit. Alternatively place the unit over the lip of a cup with the
probes on the inside edge and fill the cup with cold water until the unit beeps. By
undertaking this operational test you can be more confident in using it with hot liquids.
Storage of the unit
The suggested method of storage is to use the two magnets incorporated in to the top
of the unit and attach it to the outer frame of a fridge, microwave or other metallic
surface. To prevent the battery draining accidentally the unit should not be stored in a
cutlery drawer where probe contact with the cutlery will cause the unit to continually
beep and consume the battery. Storage within a small plastic bag or box would prevent
this happening.
Cleaning the probes
A damp cloth can be used to clean the probes but note that the units must never be
immersed in liquid as they are not sealed and damage to the electronics will result. Do
not use any cleaning materials or fluids that contain scouring agents, alcohol, spirits or
solvents (turpentine) as these agents can damage the plastic case.
