Mains Operation and Battery Operation

The MSK 25 may either be mains operated or be battery operated (battery built-in).

Mains Operation

Only the wall power supply delivered may be used for power supply. Connect it to the voltage supply socket on the right hand side of the instrument.

Sustained continuous operation (incl. MPEG option) is possible in case of an LNB power consumption of no more than max. 300 mA. Additional current will be drained from the battery built-in if the power consumption is higher than that.

In case of any longer-lasting placing-out-of-operation, connect the MSK 25 to the mains supply occasionally (trickle charge).

Make sure that the wall power supply is not connected to the instrument but for voltage feed. Otherwise the battery of the MSK 25 will be discharged!

Battery Operation

Battery operation is only possible if the battery is sufficiently charged. Otherwise the MSK 25 cannot be switched on.

When completely discharged, the battery must immediately be recharged, since otherwise it may be damaged or destroyed.

Charging begins automatically as soon as the instrument has been connected to the mains supply. Battery supercharge is avoided with a protective circuit.

When switching on the MSK 25, the loading capacity of the battery is indicated for appr. 3 seconds.

The maximum operating time with a fully charged battery is appr. 2.5 hrs, in case of an LNB supply current of 150 mA.
