4 Maintenance
The MIDAS SVX2 is completely solid state, and therefore requires very little maintenance. Other
than keeping the instrument relatively clean (as described in Section 3.3, Recovery), the only
procedure that the customer will be required to carry out on a regular basis is to change the
batteries. This Chapter also covers details of the o-rings that are fitted to the instrument, and
which should be checked periodically for damage and replaced if necessary.
There is a small chance that pressure can build up inside the instrument housing
.

section 4.1.1 Removing the End Cap Safely
4.1 Changing Batteries
The MIDAS SVX2 accepts 8 x C cells, of either 1.5v alkaline or 3.6v Lithium type. These cells are
arranged in series, so the output voltage is 12v (alkaline) or 28.8v (Lithium). Some example
scenarios for lifetime of these batteries are given in Chapter 2.4.2
The batteries are located in a holder in the top of the instrument, and should be accessed by
removing the connector bulkhead.
1. (This step may be omitted)
For easier access, remove the instrument from the protective cage by loosening the M10 nuts on
the polypropylene clamps. Gently lever these clamps apart, using a screwdriver if necessary.
Slide the instrument out of the cage, in either direction.
2. Remove the 3 M5 x 20 socket cap screws in the connector bulkhead, using the Allen key
provided. Note that these screws are titanium, and should be replaced with titanium screws if
lost. Other materials may suffer galvanic corrosion and may be destroyed.
