3.2.6 INDICATOR LAMPS
Stimulus The Stimulus lamp lights green while a stimulus is being presented.
Ext. Range The Ext. Range lamp lights red when the extended pump-pressure
range of –600 daPa to +400 daPa or the extended sound pressure range
are selected.
Power The Power lamp lights green when the ZODIAC 901 is switched on.
Status The Status lamp lights steadily green when a measurement is in prog-
ress. It flashes green if the ZODIAC 901 is waiting to make a measure-
ment when no cavity is detected. It lights red when a measurement has
been interrupted by a leak, a noise or the pump reaching the end posi-
tion. This lamp is duplicated on the probe.
Leak The Leak lamp lights yellow if the seal between the eartip (also called
the “probe tip” or “probe cuff”) and the ear canal is not airtight. This
lamp is duplicated on the probe.
3.2.7 LIQUID CRYSTAL DISPLAY
Liquid Crystal
Display The Liquid Crystal Display (LCD) can show both textual and graphical
information about the functions of the ZODIAC 901 and the results of
tests. It can display tympanograms and other Cartesian graphs during
measurement. For Tympanometry and Reflex measurements, the dis-
play can also emulate accurately the panels of a pair of moving-coil me-
ters (see, for example, Fig.4.3 and Fig.4.4). Each test mode and
supplementary function has its own screen display layout, which has
been optimized to convey information relevant to the function.
Contrast The contrast of the LCD may be altered using Alt. Select (§5.1.5) or in
System Setup (§7.2). This value is saved to NOVRAM, i.e. the LCD will
have the new value next time the instrument is powered on.
Menu Every display layout, however, contains a lower sector consisting of a
menu with five panels. Each panel shows the function of the
Softkey im-
mediately below it. At the top of each menu in the centre is a descriptive
title such as “Operation” which identifies the current operating mode.
The operating modes are: Select, Operation, New Patient?, Erase Data?,
Select Default Configuration, Alt. Select, Setup, Printer, and Marker.
Main Display The second line of the (main) upper part of every display layout also
contains a descriptive title with several components, as follows:
Mode : [ Activity ] Ear [ Earphone ]
