button and zero the gas sensor(s) as described in either
Section 3.7 or 3.8.

3.6 Battery Charging
When the “BattLow” message is displayed (refer to Section 2.8), the in-
strument must be recharged using the supplied battery charger.
Important!
The battery has a long shelf life, but it is recom-
mended that the battery be recharged once a month if
left unused. Batteries that have not been charged for several
months should be given at least two charge/discharge cycles
before using the instrument.
As with all rechargeable batteries, there are guidelines that should be
observed: The battery should normally be charged at room temperature.
Charging at temperatures below 54 °F (12 °C) should be avoided since
this may cause a false indication of when the battery is charged, and
could also damage the battery.
Before beginning the charging process, fi rst ensure that the instrument
is switched OFF. Next, plug the supplied charger into the appropriate AC
wall socket (an optional 12 VDC charger with cigarette lighter adapter is
also available). Then plug the charger’s output connector into the instru-
ment’s charging socket (Figure 1, Item G).
The word “CHARGING” appears while the battery is being charged.
Charging time is approximately 2 hours.
Note:
If the battery is deeply discharged, the display will
remain blank for a few minutes before the battery begins
charging.
Once the battery is fully recharged, the instrument will emit a beeping
tone for 30 seconds and display the word “CHARGED”. At this time un-
plug the charger and remove its output connector from the instrument.
