G-858BP Backpack Mag Operators Manual
Pressing the POWER key when the Main Menu or Magnetometer Menu is displayed will shut the unit off.
At other times, the POWER key is ignored
Note: To shut the unit off, press ESC until the MAIN MENU, G-858
MAGNETOMETER menu is shown, then press POWER.
Try not to disconnect the battery cable during use. If the battery cable is disconnected, some of
the most recent data may be lost. Every effort has been made to protect your data in this event. However,
depending upon what the microprocessor was doing at the time power was interrupted, data corruption may
occur.
The unit will power itself off when the batteries reach a low voltage condition. Data back to the
last position marker will be lost, however.
Note: The gauges on the left of the display show the battery power and
memory left in the G-858BP. You should keep track of these indicators.
High-pitched sounds coming from the G-858BP are normal. Capacitors used on the internal
circuit boards exhibit a piezo-electric effect, and create the buzzing noises.
Note: You should allow the sensor to warm up for 5 to 10 minutes before
starting the survey, depending upon ambient temperature. During the warm up
period, the unit may display an “inoperative sensor” message. If this happens,
simply unplug the sensor and plug it back in, or cycle the power of the G-
858BP. See the later section “Warming up the G-858BP” later in this chapter
for the proper procedure.
Using the menus
Selecting fields in a menu
Menu fields are highlighted by pressing the up and down arrow keys. There are 3 types of fields
which may be highlighted.
Scroll list.
A scroll list is indicated by the angle brackets, < >, on each side (see the “Baud rate” field in the menu
example below). Press the left and right arrow keys to scroll through a list of options. You do not need to
press the ENTER key. Simply move out of the field with the up or down arrow key, or press ESC to move
up an entire menu level.
Numeric entry field.
A numberic entry field is indicated by square brackets, [ ], on each side (see the “QC warning level”
field in the menu example below). Press the DEL key to delete the number that is there, type a new
number, and press ENTER. Using the up and down arrow keys to move out of this field without first
pressing ENTER will cause the numeric value to return to the last value.
Note: Don't forget to press the ENTER key after entering the desired value.
You can also move the cursor within a field by pressing the arrow keys to
select and change individual digits.
