Friendly Robotics Robomow RL350 Operating & Safety Manual page 35

The LCD on the Manual Controller will display the text seen in Figure 4.4 and the battery icon will
continually move from empty to full to show the charging. Once the battery is fully charged, the message
will change to that as shown in Figure 4.5, reminding you to keep it connected to the charger until the next
use.
Charging is such an important aspect for assuring good performance and Power Pack life that a special
alert and power management system is incorporated into the mower to remind and alert you when the
proper charging process is not occurring.

The importance of proper charging and maintenance of the
Robomow Power Pack cannot be stressed enough.

4.3 Power Management & Charging Alerts
The Robomow is equipped with a sophisticated power management and alert system that operates at two
levels; 1) to use the energy provided from the Power Pack in the most efficient manner during operation
and non-operation and 2) to help remind or alert you when the charging system is not being used properly
in order keep the Power Pack in top condition for peak performance and service. Level one is a somewhat
transparent level to the user, but under certain conditions will communicate information to the level two
system in order to alert you that something regarding the Power Pack and charging system needs your
attention. It is the level two system that communicates to you through LCD messages and audio.
The basic assumption of the system is that the Robomow will be connected to a charger at all times when
a Power Pack is inserted in the mower, except when in operation. This assumption is made because this
is the only way to insure that the Power Pack will always deliver satisfactory performance during operation
and will also provide a reasonable service life. Given this, the system alerts the user at several different
levels and frequencies when this is not happening. In addition, the system can also alert the user when
something has interrupted the charging operation, such as a loss of power to the charger for example.
