Screen Descriptions
Alarm Screens
Any of five alarm screens may appear under certain conditions: no external antenna
connected,
low battery, extreme low power, low data memory, and kinematic. These alarms
are discussed in the following paragraphs.
No External Antenna
The ProMark2 will not allow you to collect survey data without the external antenna. The No
External Antenna
alarm, Figure 4.26, appears if one of the two following conditions occurs:
You attempt to begin survey data collection (you select
Collect Data from the Survey
screen) without an external antenna attached. To rectify, press
ENTER to clear the
alarm, connect the external antenna, and begin data collection.
During survey data collection, the external antenna is disconnected. Data storage
stops until the external antenna is reconnected. To rectify, reconnect the external
antenna and press
ENTER to clear the alarm.
Low Battery
The Low Battery alarm, Figure 4.27, appears when remaining internal battery life is low. The
amount of life remaining depends upon the battery type being used (alkaline or lithium) and
the temperature at which the equipment is operating (see "Battery Life" on page 25). If you
close the Low Battery alarm screen by pressing the
ENTER key, the alarm will not appear
