an error code (see details under chapter 7 Display & operation).

Sleep mode
An internal sleep mode protects against a complete discharge of the Li-cells.
When idle, under normal conditions the LE300 goes into a standby/sleep mode.
Every 128 seconds the device will be automatically waked up to check, if LE300
is needed for charging/discharging.
If one of the Li-cells falls under deep discharge, caused by self-discharge, the
LE300 goes into a deep sleep mode. In this mode, the LE300 can only be woken
up by pressing the push button or by recharging the device (this is checked every
four mins automatically). After wake-up, a charging phase is possible.
If one of the Li-cells is critically deep discharged, the LE300 system shuts down
completely into a safety mode to protect from potential dangers that could occur
when recharging depleted lithium cells. The LE300 cannot be woken up anymo-
re. Neither charging nor discharging is possible anymore. In this case, please
contact your local BOS dealer for support.
