Additional information
• A speech test is to be performed before startup and it should be noted that if the speech test is carried out close to the portable VHF station the results may be positive even if the antenna cable is broken or
• Use a loud voice for speech communication and hold the microphone close to the lips. Otherwise noise can be intrusive and make understanding difficult.
• Use only microphones or headsets which are suitable for use in air- craft. Incoming radiation on the equipment antenna can affect the integrated amplifier of the microphone (feedback). This is noticeable in the portable VHF station by whistling and/or heavy distortion. The described disturbances can occur in different ways on the different transmission channels.
• he PTT (press to transmit) button can stick and cause continuous transmission. Therefore, when transmitting observe the arrow in the top line on the left next to the active frequency display and check that when the PTT is released the arrow disappears.
• The fuse may be replaced only by the specified fuse, otherwise uncontrolled damage can occur at the VHF transceiver.
