Connection of a tape or cassette recorder

IIyou want to leed audio signals tram a tape recorder or a cassette recorder into the transmitter to complement the normal voice trans- mission, plug these sets into the 3.5 mm jack 11).In this case the microphone is automatically switched off.

Always use the record/playback connector 01the tape or cassette recorder. II the set is only equipped with an output lor headphones or an external speaker, please observe the lollowing: the line input is designed lor inputs levels between 75 mV and 1.5 V. Transient peaks on the input exceeding 1.5 V are compensated by the high- grade limiter. This should, however, only happen under exceptional circumstances. The better way is always to reduce the input level by means 01 the volume control on the recorder. Sources with a lixed

output level 01 more than 1.5 V require the use 01an attenuator which should be inserted between the source and the transmitter.

Adjusting sensitivityof microphone and line input

Under the cover @you will lind a control @Ior the sensitivity 01 the micraphone or line input which works similar to the level control <)n a tape recorder (Iig. 5). Besides the manual control which reduces the input gain il a certain threshold is exceeded (i. e. il the swing 01 the transmitter reaches:t 40 kHz). The lactory setting is appropriate lor signals 01 a medium level. Under normal conditions, this setting IS adequate and should not be altered. In case which require changing gain proceed as lollows:

Selecting frequencies

Switch @on the transmitter selects one 01three Irequencies, i. e. 36,7 MHz, 37,1MHz and 37,9 MHz (see tig. 5 b).

Fastening neck strap and clip

The set is supplied with a neck strap and a clip lor lastening the set to the body. The strap must be attached at the slots shown in lig. 6. When lastening it must snap into place with an audible click.

Switch on transmitter and receiver. Make sure that both sets are

operating at the same Irequency. Turn the contral @ to its left stop. Speak into the microphone at normal voice. Optium results have in practice been reached by speaking a long "aaahh" into the micro- phone. During this level check hold the transmitter in into normal operating position.

Listen to the signal with a set 01 headphones while you speak into the microphone. Slowly increase gain until the volume ceases to rise. Now reduce the setting by a quarter-turn.
