Discreet mode and zeroise
Discreet mode switch
The discreet mode switch allows the operator to control audio and light emissions from the radio,
that is to say, that all of the speakers and backlighting on the device turn off when in discreet
mode, allowing the device to operate with reduced sound and light signature.
Discreet mode on
Discreet mode off
Zeroise
The discreet mode switch can also be configured to zeroise (erase) or lock the radio to prevent
unauthorised access to the unit when compromised. By default, the zeroise function is set to
prompt the user with erase or lock options.
Turning Discreet mode on and off
Turning on discreet mode ensures that the radio will operate without emitting light or sound.
WARNING: If the H-250 Discreet Mode Override audio option is enabled, the audio
will still be emitted from any audio device connected to the H-250 (J5) port. Contact your
HF Network Administrator for more information.
