Controls and Display
Under certain environmental conditions (such as in cold and/or dry areas), electrostatic
discharge (ESD) can cause the display to go blank. Pressing and holding the “Up” button
for at least three seconds will reset the display and restore its normal operation.
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.
