Symbol Explanation
Green info/
Yellow warning
Green = GPS compass active.
Yellow = problem with e.g. GPS
reception.
Table42: Symbols
!
NOTE: After starting up the rig's electrical system it may take several minutes before
the symbol becomes green. This is because the antennas have to establish contact
with the satellites.
If the symbol does not become green then this may be due to several causes, e.g.:
n No satellites available
n The antennas are covered by snow
n Open circuit in cable between the antennas and the electronic unit
If the symbol remains green, deactivate the GPS compass in the F4 menu and use the aim
device in the traditional way.
9.1.4 Drilled length instrument
In order to control drilling length and penetration rate, the system is equipped with a drilled
length sensor. This is mounted on the rock drill cradle and is connected to the display to-
gether with other components in the system. The drilled length instrument can be con-
figured to show either the actual drilled length, hole length measurement or the vertical
depth, vertical depth measurement. In the latter case, the instrument takes into account the
hole inclination, and the value that is displayed is therefore less than the actual drilled
length.
Menus
The drilled length instrument is accessed by pressing button F3 in the left-hand edge of the
display. This provides direct access to the drilled length instrument menu.
