There are few user-serviceable parts on the Optisure Remote. These include cleaning
the mirror in the sensor and the removal and replacement of the AC power supply fuse.
5.1 Safety
!
This equipment operates from power supply voltages that
can be lethal and at pressures (depending upon application)
that could cause injury.
Insure that any test installation meets the standards
described in Section 2.3 of this handbook.
Under NO circumstances should the instrument case be
removed or the air vents covered or in any way restricted.
Maintenance and repair, other than that described in this
section, must only be carried out by trained personnel and
the instrument should be returned to the manufacturer for
this purpose.

5.2 Fuse Replacement
If the instrument fails to operate after it has been connected to an AC power supply
(85 V to 264 V, 47/63 Hz) and switched on, proceed as follows:
1. If the power supply cable is fitted with a fused plug, switch off the power
supply, remove the plug, check and, if necessary, replace the fuse. If the
instrument still fails to operate, after fitting the fuse and switching the
power supply on, proceed as follows (see Figure 25).
