This option allows you to set how close you must come to

the destination before the alarm begins to sound.

After the alarm sounds, you can reset the arrival alarm to a

shorter distance, but this shorter distance will apply to the

next target and not to the current one. If you want the

alarm to sound again when you come within a shorter dis

tance to the current target, first select another target des-

tination and then reselect the original target.

Setting the PDOP Alarm: This turns on or off the alarm

that can sound whenever ProMark3 has lost its ability to

compute accurate position fixes due to poor geometry of

the GPS constellation. Generally, PDOP values less than or

equal to “5” are indicative of good operating conditions.

So it is a good idea to set this alarm to “5.” To turn off the

PDOP alarm, enter “00.”

Note: Apart from the Arrival and PDOP alarms, ProMark3

will generate a warning message on the screen in each of

the following two cases:

- “Low Memory.” This message will appear when the

receiver is running out of memory. If raw data is being

collected with the Surveying function or a GIS job is

being logged, then the occurrence of this message will

automatically stop data logging. You will however be

allowed to enter the attribute values of the current GIS

feature before the job is closed.

- “Out of Memory.” This message will appear when the

memory is full. The occurrence of this message will

immediately end raw data collection or close the cur-

rently open GIS job and you will not be able to log any-

thing until you free some space in memory.

North Reference

This option allows you to define the type of North refer-

ence you want ProMark3 to use. This can be True North,

Magnetic North, Military True North or Military Magnetic

North.

After selecting the North Reference option from the Setup

menu, tap the desired North Reference from the displayed

list.
