garden layout.

Calibration of guide is done automatically rst time the mower leaves the charging station in the
following situations:
• New mower rst start up
• Always at Test Out
• After changing guide width to Medium or Wide
• After performing Factory reset
• After changing main circuit board
• After main software update
Sub System Software
In mower menu Tools -> Info -> General, the line “Sub-ver” has been added. That software con-
trols the cutting motor. The Sub system software is updated together with the Main and MMI soft-
wares when Automatic programming is done in Autocheck EXP.
Test Out and Test In
As a result of improved Calibration of Guide some changes have been done in the Test Out and
Test In procedure.
• Test Out must be done before Test In.
• If Test In is done before Test Out the mower will run on top of wire to the charging station,
irrespective of guide width setting. This should not be considered as a valid test.
Demo mode
Demo mode is available in menu Tools -> Special Settings -> Demo Mode. In demo mode
Automower® 305 works without starting the blade disc. The mower varies running with charging at
four minute intervals.
Note!
- It is strongly recommended to use demo mode whenever running Automower®
in public demo areas, for example inside a dealer’s shop. Blade disc is
switched off in demo mode for increased safety.
- Always remove the blades from the blade disc whenever Automower® is
demonstrated in public areas for increased safety.
- Demonstration of Automower® without using demo mode may only be done if
the mower is constantly under observation.
