significant errors in readings.

REPLACING BATTERIES
Figure 4: Replacing Batteries
Before using the GasCheck G instrument, ensure the batteries are fitted
correctly or ensure NiMH (rechargeable) batteries are fully charged
before use.
To fit or replace batteries you must first remove the battery cover from the
rear of the instrument. This can be done by prying open the battery clip
with a fingernail or screwdriver.
Removing the battery cover will reveal a battery hold which requires 4 x
AA size batteries. Before removing old batteries or fitting new ones, unclip
the battery holder from the instrument by prying apart the PP3 type clip as
shown in the illustration.
Once the battery holder is disconnected from the instrument, the batteries
can be removed or replaced. Care must be taken when refitting the
batteries to ensure that they are the correct polarity. Polarity markings are
molded onto the battery holder plastic.
The battery holder can be reconnected to the GasCheck by firmly pressing
the two halves of the PP3 clip together. Care should be taken to ensure the
polarity is correct. See the PP3 diagram (Figure 4).
The battery pack is then laid within the instrument and the battery cover
refitted. Take care not to trap wires when refitting the battery cover.
