                                                              Spurious Rejection:                 Better than 85dB
                                                              Conducted Spurious Emission:        <-57dBm
Talk Around                                                   Selectivity -6dB:                   >12kHz
 The feature causes a button to select simplex operation                 -60dB:                   <30kHz
on semi-duplex channels: the transmit frequency               External Audio Output Power:        12 watts into 4 ohms
becomes the same as the receive frequency (regardless                                             with < 5% THD
of any programmed offset for the channel).
Note: This feature has no effect on simplex channels.         Transmitter

 When the Voice Scrambler feature is enabled, pressing        Hum & Noise Ratio:                  Better than 45 dB (25kHz/step)
a button toggles the Scrambler on and off.                                                        Better than 40 dB (12.5kHz/step)

                                                              Microphone Impedance:               600ohms
 When the “alarm” function is enabled, pressing a button
                                                              Microphone Sensitivity:             -48dBm (3.0 mV)
causes the radio to revert to a specially designated
channel, and causes the special “alarm” identifier code to
be transmitted automatically.                                 Physical
                                                              Size (WHD,approx.):                 178mm x 60mm x 195 mm
Note: This feature is only available as a “Secondary”         Weight (approx.):                   2.2kg
accessory to prevent accidental activation.
