50 | Modes
If you turn off the radio in the Silent Emergency Mode, the radio switches to pseudo power off state. In this state, the
radio appears to be turned off. However, the radio is still on and in the Silent Emergency Mode. On turning the radio
on during the pseudo power off state, the radio acts as during turning on and still is in the Silent Emergency Mode.

Invisible Emergency

It is possible for the service provider to disable visual and audible indications of performing Emergency Operations
on the radio. The purpose of this feature is to hide the fact of using Emergency Operations in a critical situation (e.g.
direct attack on the user) and thus to provide additional layer of safety.

Disaster Alert

Disaster Alert call is a broadcast emergency call initiated by the radio, with emergency pre-emptive priority that
everyone in a broadcast area can hear. This feature is specifically designed for catastrophic situations, such as
earthquakes, and has the highest priority over other calls. All radios under Disaster Alert display emergency
notification on their screens. The alert message, its duration and destination talkgroup can be configured in the
codeplug.
In order to initiate Disaster Alert, switch the radio to Disaster Alert mode and press PTT button. When the call ends,
the radio will exit the Disaster Alert state.
During Disaster Alert, other functionality is impacted:
• When Disaster Alert begins, any other ongoing services are terminated.
• No other services can interrupt this type of call.
• Hot Mic functionality cannot be used.
• Speech can only be in Clear mode, even if any of the encryption services are enabled. The only exception is E2E
Encryption.
Note: Not all infrastructures support this feature. Please consult with your service provider before enabling
this feature.
