Emergency Operation

TX output power ................. ≥ 2 W into 50 Ω (with modulation) @ 9 VDC
TX modulation depth ............. ≥ 50% @ 9 VDC
RX sensitivity .................. ≤ -93 dBm for a (S+N)/N ratio of
Panel & Display backlight ....... switched "OFF"
Speaker output .................. switched "OFF"
Headphone output ................ operating
CAUTION: For power-supply voltages below 10 V the speaker output of the
transceiver will automatically be switched "OFF", without
notification for the pilot!
Depending on settings in Installation Setup "LOW BATT" may be
indicated if supply voltage drops below a predefined threshold.
If the threshold adjusted within the range 10.3 ... 10.5V is
reached the "LOW BATTERY" warning indicates the user, that he
should connect his headset because the speaker may be switched
"OFF" soon).
