Voice and Display Messaging
User may select English, Spanish, French or German
for voice and display messaging.
Battery Gauge
This consists of B (for battery) and a maximum of 6 bars,
as illustrated. Six bars represent full charge, while fewer
bars indicate various stages of charge. When all bars
are depleted, the instrument will run for more than an
hour, after which time a low battery alarm is indicated by
two beeps every 15 seconds. Low battery alarm will
continue for at least half an hour, after which instrument
will beep continuously and shut down. If alkaline
batteries power instrument, battery condition is
indicated on the display, not by bars, but by battery
voltage. A fresh alkaline pack will read about 5.8 volts,
and low battery warning commence anywhere from 4.0
to 4.2 volts, model dependent, while shut-off occurs
between 3.68 and 3.95 volts, model dependent.
Pump or Diffusion Mode of Operation
User may choose between pump and diffusion mode of
operation. If pump is selected, 'P' is displayed in the
lower left corner of display and all the benefits of internal
pump operation are available. In diffusion mode, 'D' is
displayed. If pump mode is selected and pump fails,
instrument automatically switches to diffusion mode for
continuous operation and protection.

time display. If daylight savings time is selected, the
time will be automatically updated.
