System Maintenance
Fido X4 requires basic maintenance and cleaning to ensure optimal performance throughout
operation. All basic maintenance can be completed by the end-user. Fido X4 does not require
periodic calibration or factory-performed maintenance.
8.1 Replacing the Sensing Element
The sensing element will periodically need to be replaced. The Fido X4 determines when
replacement is needed, based on Verification results and internal diagnostic parameters that
are continuously monitored by the system. If the sensing element needs to be replaced, the
Fido X4 will notify you during operation as described in Section 5.2.1, "Verification Failure."
Note:
If possible, perform the procedures in this section over a raised soft surface (for
example, a table covered with a towel) to minimize the risk of dropping the sens-
ing element from a height and breaking it.
8.1.1 Removing the sensing element
Caution:
The sensing element is HOT.
Handle with care to avoid burns.
When handling the sensing element, take care only to touch the end of the Ele-
ment that is marked with a dot (Figure 8-1).
Caution:
Breaking a sensing element will create sharp edges and glass shards
that can cut or puncture skin.
• Do not store sensing elements in clothing pockets.
• Do not put a sensing element where someone might sit or step on it.
• Properly dispose of used or broken sensing elements with care to avoid
injury.

Procedure
Step 1:
Turn the Fido X4 over so the underside is exposed, with the battery pointing
toward you. Keep the unit horizontal as shown in Figure 8-2.
