Attachment of the transmitter to clothing
The SK 500 transmitter is best attached to e.g. the belt with clip
The clip is detachable so that you can also attach the transmitter with the
antenna pointing downwards. To do so, withdraw the clip from its fixing
points and attach it the other way round.
Attachment of the microphones
The microphone clips enable the attachment of the ME 2 and ME 4 clip-
on microphones to clothing (e.g. tie, lapel).
The ME 3 headmic is adjustable to comfortably and securely fit your head.
Positioning the microphones
The ME 3 and ME 4 microphones are directional microphones, i.e. their
sound inlet should always be directed towards the sound source (e.g. mouth).
The ME 2 with omni-directional pick-up pattern picks up sound equally
from all directions. It is the best choice if movements of the speaker's head
have to be compensated for.

the battery capacity is sufficient,
the battery is going flat,
immediately replace the battery.
