B1
- Lithium battery holder. We recommend replacement when the voltage is lower than 2.5
V, or at least once every three years. We recommend the batteries be replaced with the
PBX off. Before replacement we recommend saving the program of the PBX and the
accounting data in a PC. After replacement check the date, time and program of the
PBX and, if not correct, make the correct adjustment. Never change the batteries when
the PBX is on.
WARNING! Use only a tool made from insulating material for replacement!!!
