Replacing batteries
Removal or replacement of the
lithium battery in potentially combustible
atmospheres may compromise intrinsic safety. The
lithium battery used in the ToxiPro may only be
removed or replaced in an atmosphere that is known
to be non-hazardous.
To replace the battery:
1.
Turn the ToxiPro off. If the ToxiPro is in Always
On Mode, see section 2.8.1 for further
instructions.
Note: Failure to turn the ToxiPro off prior to battery
removal may cause loss of data in the ToxiPro’s
datalogger.
2.
Remove the two screws from the back of the
ToxiPro. One is located under the clip. The other
is located near the bottom of the instrument.
3.
Remove the front housing. The main board will
stay attached to the rear instrument housing. The
battery is located directly above the display.
4.
Remove the old lithium battery. If necessary, use
a small screwdriver to gently pry the battery out.

removed.
5.
Install the new battery. Be sure to align the
polarity of the battery in accordance with the
diagram on the face of the battery compartment.
Use only Panasonic #CR2 in
the ToxiPro.
6.
Once the new battery is installed, the instrument
will automatically restart and the ToxiPro will
show “F 0” on the display and will beep 6 times
upon startup. It will then go into the set time/date
mode.
The next five steps describe programming the time
and date.
7.
Press and release the MODE button to advance
the setting by one. Hold the MODE button down
to scroll rapidly. Afternoon and evening hours are
differentiated by a dot below the colon on the
display.
10 a.m
.
10 p.m
.
Once the appropriate hour setting is shown, wait
5 seconds and the minutes setting will start to
blink.
8.
Adjust the minutes setting with
the MODE button, then wait 5
seconds and the months
setting will be shown.
9.
Adjust the months setting with
the MODE button, then wait 5
seconds and the days setting
will be shown.
10.
Adjust the days setting with the
MODE button, then wait 5
seconds and the year setting
will be shown in two digit
format.
11.
Enter the last two digits of the
year with the MODE button,
then wait 5 seconds and the
instrument will continue to the
normal start up sequence as
discussed in section 2.1.
12.
Replace the front cover plate.
13.
Reinstall the screws that were removed in step 1.
14.
The ToxiPro must be calibrated following
replacement of the battery. Once the sensor has
stabilized, calibrate the detector. For ToxiPro O
2
units, perform the Fresh Air/Zero Calibration as
described in section 3.3. For ToxiPro units,
perform both the Fresh Air/Zero calibration
(section 3.3) and the Span calibration
(section 3.5).
