2.6.5 Special settings
The Special settings sub-menu contains the settings
that are only accessible to dealers.
Override loop detection
This function makes it possible to temporarily switch
off a mower's loop detection, i.e. to be able to run it
without the charging station and boundary wire being
installed. One such occasion can for instance be a
demonstration of a robotic lawnmower at the home of
a customer.
The function is reset automatically when the mower
is turned off and on using the main switch.
Demo mode
In demo mode the robotic lawnmower works without
starting the blade disc. The mower alternates be-
tween 4 minutes operation and a short charge.
The Demo mode is ideal for use in installations such
as in shops or exhibitions.
The function is reset automatically when the mower
is turned off and on using the main switch.
Installation settings lock
When the installation lock is activated, it is not pos-
sible to change any settings in the Installation menu
from the main menu. This function must be deactivat-
ed to carry out any changes to the installation settings.
Override ultrasonic
This function makes it possible to turn off the ultra-
sound. When ultrasonic has been turned off from this
menu, the mower will continue at full speed (65 cm/s)
the whole time. Once ultrasonic has been turned off
from Accessories - Ultrasonic, the mower will con-
tinue at reduced speed (46 cm/s) the whole time.
