The M705 extension is a unit that can be joined to the M760, M760E, M780, i760, i760E and i780
sets to form an aesthetically pleasing unit.
It is a module containing 20 additional keys without back-lighting, the top part of which can hold a
DECT handset charger (type MC900). The 20-button keypad is identical to the M760, M760E, i760

each set.
The DECT handset charger has two power supply contacts on which the DECT handset sits.
