NOTE: It is possible that the instrument may
display an alarm condition upon entering the
monitoring mode (indicated by a flashing alarm
symbol). This is due to the sensor taking time to
settle after switch on. It is NOT a fault. Press the
large button to cancel the alarm after a few
seconds.
If configured to do so, the instrument will give an
intermittent audible blip and/or visual red flash to
indicate correct functioning of the instrument.
Selection of these ‘confidence’ signals will affect
battery life according to the table in Section 4.2.
Pressing both buttons together will switch the
instrument off. The instrument may be configured
in such a way that it is not possible to turn it off via
the push buttons. In this case, only a supervisor
with a computer link can switch the instrument off.
