USB Host & Device.
A nine-contact female connector (Fischer
type). Depending on how it is configured, the USB port can
be used in two different ways:
1. For a USB host, such as a mass storage device using
optional device cable P/N 702104.
2. For a USB device allowing ProFlex 800 to be seen as a
disk from the computer connected to this port. In this
configuration, files can be transferred between the
ProFlex 800’s internal memory and the computer using
the USB cable provided (P/N 702103).
Display Screen.
The display consists of a 128 x 64-pixel, 1.5-
inch monochrome yellow screen using organic LED
technology (OLED).
Used in conjunction with the Scroll button, the display screen
allows you to view different pages of information. See
Display
for a detailed description of the
information available from this screen.
After a few seconds of inactivity (i.e. Scroll button idle),
screen luminosity turns from high to low level.
Power button.
To turn on the ProFlex 800, hold the Power
button pressed until the power LED lights up.
To turn off the ProFlex 800, hold the Power button pressed
until the “Ashtech” screen is displayed. Then release the
button and wait until the ProFlex 800 shuts down.
Power LED.
•This indicator light is off when the ProFlex 800
is off and no external power source is connected to the DC
power input.
•
It is on and red when an external power source is present
at the DC power input and the ProFlex 800 is off.
•
It is on and green when the ProFlex 800 is on, regardless
of whether it is powered from the internal battery or an
external power source.
•
It is blinking red when the sleep mode has been enabled
and the receiver is currently running a session. With the
sleep mode enabled, the receiver is idle between any two
sessions, as if it were virtually turned off, and the power
LED is also turned off during this time.
