1.2.5 Build-in microphone with indicator
DIS uses a highly sensitive condenser electret microphone on a flexible gooseneck
frame. The microphone has a red LED that indicates the type of incoming or outgoing
communication by a solid light or flashing. With an outgoing voice connection, the
microphone indicator constantly glows red, with incoming - flashes red. The microphone has
a wide range of perceived frequencies and a one-way directionality that minimizes the effect
of third-party interference.
1.2.6 Headset or external microphone with a push-to-talk button
A handset of any model or any manufacturer (not included in the scope of supply) with
the following parameters can be used:
Microphone type – electret;
Microphone sensitivity – at least 30 dB;
Speakers impedance – in the range from 32 to 300 Ohm;
Earphone frequency range – at least 100-16000 Hz.
Instead of a headset, an external microphone with a push-to-talk button can be used.
Selection of the headset type is made using the DIP switch SW5 on the main board of the
DIS.
The pin assignment of the connector for connecting the specified additional equipment
must comply with the information given in Table A.2 (Appendix A).
