Introduction

The Mikroport-transmitter SK 1010 is designed für single-channel use in the frequency ranges 30 to 45 MHz and 138-220MHz. The transmitter together with a microphone and a suitable Mikroport- receiver e.g. HDE 300-7 or EM 1001, forms a wireless microphone system of high quality.

The transmitter is powered bya commercial 9 V-battery (IEC 6 F 22) or a rechargeable nickel-cadmium accumulator. The accumula-

tor may be recharged from the automatic charging unit

SZL 1010. Charging contacts are provided on the side of the receiver.

Together with the screw-in microphones MKE 2010 and MKE 4010 the transmitter forms a unit not larger than a conventional micro- phone. This complete unit may be easily hand-held for reporting or carried around the neck as a Lavalier microphone. A carrying device is included in the packaging.

If the transmitter ISto be worn inconspicuously beneath the clothing microphones are available which are connected via a short cable to the microphone socket of the transmitter.

Inserting the battery

To insert the battery (IEC 6 F 22, e. g. Mallory MN 1604 or NC-accumulator Varta Tr 7/8) please open battery compartment @ by pressing gently as indicated by the arrow In fig. 1. The lid can then be slid off. When inserting the battery, please note that the negative terminal must fit into the large contact opening of the battery contacts. The unit will only operate If the battery IS inserted wlth correct polarity.

Close the lid until it snaps in audibly. The hinge of the battery compartment lid cannot be destroyed by mishandling since it simply comes off and can snapped in again.

Microphones

The electret microphones MKE 2010 and MKE 4010 (fig. 5) have been especlally developed for use with the transmitter SK 1010. The screw-in microphone MKE 2010 has an omnidirec!ional characteristic and features low handling noise sensitivity. It is to be preferred when several people speak from different directions into the same microphone. In noisy environments, reverberant rooms or when there is a danger of acoustical feedback, we recommend using the screw-in microphone MKE 4010 with a cardioid directional charactenstic.
