3-3 Operating Controls and Indicators
The operating controls on the Model HI-3510 are the ON-
OFF switch and the MODE switch, both of which are
located on the side of the unit. In addition, the Model HI-
3510 has three alarm indicators: Two visual indicators
consisting of an LCD display panel and red LED warning
light, both located on the top of the unit (see figure 2),
and an audible alarm produced by a beeper located with
the unit. In addition, there is an audio output jack to
which the furnished acoustical earpiece can be
connected.
3-4 Operating Procedure
To turn the unit ON, place the ON-OFF switch in the ON
position. The unit will respond with a three second beep
and its red LED will glow to confirm that the unit is
operational. In addition, all segments of the LCD display
will be on during this three second interval. The LCD
display will then indicate the preset alarm warning level
for about seven seconds. The unit will then respond with
a short beep and red LED flash. At this time; the unit is
operational and will indicate the power density in the area
as well as the ratio of the power density in the area to
the preset alarm warning level (% ALARM LEVEL bar
graph). This display is normalized to the programmed
alarm level so that the alarm indicates when the bar
graph reaches 100%. Using this display, the wearer can
tell how close he or she is to the alarm without being
exposed to an alarm power level. (If you are working in
a noisy environment, connect the acoustical earpiece to
ensure hearing the audible alarm.) When there are no RF
fields present higher than the preset alarm warning level,
there will be no further alarm indications from the unit.
