AC supply and does not have an integral ON/OFF
switch. To disconnect the power switch the mains
power point switch to OFF or unplug the power supply
(AC-DC adapter);
▪ Clean the headset and ear tips regularly ----- use a
cloth for the headset and warm water and a mild
detergent for the ear tips (after removal from the
headset); (for commercial applications spare ear tips
are available for purchase);
▪ Keep away from heat sources such as hot-plates, and
heat generating appliances;
▪ Keep away from water and other fluids;
▪ Repairs must be carried out by qualified personnel;
▪ We suggest that a power surge protector is connected
between the mains supply power point and the AC-DC
