2. Do a full charge to the battery every 3 months.

• Charge the battery with AC grid until the ‘CHG’ LED light on PM335 unit or ‘FLOAT’ shows on the monitor

Every 3 months, the monitor will display a code (8018) suggesting maintenance. If you have performed maintenance and

would like to turn off this alarm, press ‘SILENT’ button for 1s. Only the energy consumption of the loads connected on the

PM335 is measured and calculated in the data on the Monitor.
