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 Power Supply
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.

4.3 Power Management & Charging Alerts
The RoboMower 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 RoboMower will be connected to a Power Supply 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
