When the alarm is showing the current
temperature you will see something similar to
the following.
In both modes you will notice a
symbol appear briefly in the top left hand
corner of the screen once every minute. This
is an additional indication to show you that
the alarm is operating as well as the flashing
green LED.
To switch between CO and temperature view,
simply press the Test/Mode button briefly. The
unit will also sound when pressing the button
to switch between the two display modes.
You will also notice that when switching
between modes the display will change
slightly, this is because the alarm is displaying
thePeakLevelCOreadingthatithasrecorded
inthelast4weeks,pleaseseethefollowing
peaklevelreadingfeaturesectionforfurther
description.
NOTE: If the alarm is in temperature
view and detects CO it will automatically
switch back to CO display mode.
Power pack, sounder and circuitry test

the power pack, sounder and circuitry of

Peak Level Reading feature
The alarm will record the highest reading of
COthatishasdetectedinthelast4weeks.
This information is useful if your alarm has
sounded so you can see the highest level of
CO detected during that time. It is also useful
tocheckperiodicallytoseeifareadablelevel
of CO has been detected for a short time, but
not long enough to trigger a full alarm. The
peaklevelreadingisshownbrieyeverytime

somethingliketheimagebelow.
NOTE: It is possible and quite normal
for the peak level to remain at 0ppm,
i.e. this simply means that the alarm has not
detected any CO in the last 4 weeks.

whenever a Sensor Test is carried out. (See the
next section for Sensor Test).
