ERROR MESSAGES AND TROUBLESHOOTING
Self Test Startup Error:
• If the thermometer determines an error during the
self-test phase after activation, "Er" is displayed and
3 short acoustic signals are emitted; the device then
switches off after 10 seconds.
If this occurs, remove the batteries and wait a few
minutes before replacing them in the device. Attempt
to activate the device again. If the error message should
appear again, contact a local dealer.

• If the batteries are low, the battery symbol appears.
Please change the batteries as quickly as possible.

the required power value,

battery symbol after press-
ing the POWER button.

pletely discharged, nothing will appear on the display
after pressing the POWER button. Replace the batteries.
