the service program Autocheck. A reference to
another part of the Technical handbook is also
shown in italics.
• Words written in bold refer to one of the buttons
on the mower's keypad or a button in the service
program Autocheck.
• Words written in UPPERCASE and italics refer to
the position of the main switch and the different
operating modes on the mower.

1. FUNCTION
Go to the Quick Check function:
1. Turn ON the main switch on the Automower.
2. When the main menu is displayed: Hold down the
0button for two seconds.
The version (edition and program type) is stated
on the two uppermost rows, for example 02.51
and 220 AC.
3. Hold down the Arrow back button to return to
the main menu.
It is important that the Automower is programmed
with the correct version of the mower program. The
version consists of both the edition and the program
type. The edition states how new the mower program
is. Husqvarna works constantly to improve the
behaviour and performance of the mower, which
results in new program editions. The program type
provides information about which type of mower
program Automower is programmed with. The control
box fitted on the mower and whether the mower is
equipped with any extra equipment determine which
program type the mower is to be programmed with.
There is no difference for the user between different
versions of the same edition. The versions only differ
due to differences in machine components.
