• When you release the start-button, the thermo-
meter‘s display will show the actual anti-theft time
setting. E.g. «H08» meaning 8 hours have been
selected as the time for which the thermometer
can be used before it has to be returned to the
station.
• To change the anti-theft interval setting, press the
start button again and as often as necessary until
the desired time is shown in the display.
«H--» means the anti-theft function is off, «H01»
means 1 hour setting, etc.

meter back into the station within 30 seconds.
A beep will sound, confirming the setting.
• If the setting is not confirmed, repeat the proce-
dure as described.
If the anti-theft function is enabled, and when not
in the measuring process (stand-by mode) the
thermometer will show the time remaining before
the anti-theft function shuts down its operation.
«H3.5» means the anti-theft function will shut down in
3.5 hours.
If the thermometer shows «RET» (without the battery
symbol) on its display, the anti-theft time has elapsed
and the thermometer must be returned to the station
for unlocking.
If the anti-theft function is not enabled, the display
will show «OFF» when in stand-by mode.
