MANIPULATION

Switch on the receiver:

NOTA BENE

Put the transmitters to work (see their user’s guide).

Check both transmitters and receivers for identical frequencies. Check whether or not the transmitters’ battery capacity is sufficient for the planned applications.

Sennheiser SK 50, SK 250 and SK 5000 Mikroport transmitters automatically transfer data on the condition of their batteries or rechargeable battery packs to the EM 203receiver. If the LowBatt indicator starts blinking on one of the displays, the batteries or rechargeable battery packs

of the transmitters concerned are to be replaced or recharged.
