Controls and Display
2.4.1.1 RSSI Threshold Indications
In conventional mode only if programmed, the user can see the signal strength of the last
call displayed as a signal strength indicator icon. At the start of every call, the radio will
take an RSSI measurement and set a corresponding signal strength indicator icon. The call
must be long enough for a full measurement (40 ms) or the measurement will be ignored.
The signal strength indicator icon from the last call will stay displayed until a new call is
received. The icon signifies the strength of the last received call not the current signal
strength. If the radio goes out of range because it did not receive a beacon within the
Inactivity Duration, it will automatically set the signal strength indicator to Out Of Range.
2.5 Signaling Tones
Information is communicated to users of the Viking Portable radio using signal tones and
alerts and by LED signaling. Table 2.5 shows the information and signaling tones
supported by the Viking Portable radio. If you are viewing a PDF of this manual on a
computer equipped with a sound card, click on the Message Name to hear the tone.
