1.5 Scope of Functionality
Frequency Indication
• A liquid crystal display (LCD) do the frequency indication.
• The required operating frequency is selectable with a rotary encoder.
• The relation between the real operating frequency and the shown frequency complies with
the standards (ED-23C, chapter 1.3.2).

Audio Outputs
The transceivers have four configurable outputs:
• Headphone 1 output:
o Rated output power is 300 mW into 75 Ω.
• Headphone 2 output:
o Rated output power is 200 mW into 75 Ω.
• Speaker output:
o Rated output power is 4 W into 4 Ω.
• LINE-OUT output:
o For ground station use only.
Notice: Headphone 2 and the speaker output cannot be active at the same time.
Mike Inputs
• The transceivers have four microphone inputs:
o Standard microphone input 1 (STD_MIKE1)
o Standard microphone input 2 (STD_MIKE2)
o Standard microphone input 3 (STD_MIKE3)
o Dynamic microphone input (DYN_MIKE)
• Each input can operate with one single microphone or with two microphones of the same
type connected in parallel.
AF Auxiliary Input
• The AF auxiliary input is the interface to connect an external audio source (e.g. other radio
services, music-player).
o The interconnection of multiple external audio sources on this port make an
additional external decupling/isolation resistor necessary.
o The external audio is audible only when the transceiver is in receiving mode.
o The individual audio volume is set directly at the external equipment.
