Optional Signaling LED
Optional Signaling LED
is the function that causes the LED to flash in yellow when the Optional Signaling received matches
that of the transceiver.
A user can notice by the LED that the transceiver is receiving a call.
When Optional Signaling is no longer matching due to operation of the transceiver key or upon elapse of the time configured
in
Auto Reset Timer
, the light of the LED goes off.
However, if
Selective Call Alert LED
is enabled, the LED flashes according to the configuration of
Selective Call Alert
LED
even when
Optional Signaling LED
is enabled.

Late Entry Fast Unmute
Late Entry Fast Unmute
is the function to immediately unmute the speaker before the transceiver determines whether the
received signal is encrypted upon receipt of a signal.
0
Transceiver behavior if this function is enabled
Upon receipt of a P25 digital signal, the transceiver immediately unmutes the speaker and emits the received audio from
the speaker prior to determining whether or not the signal is encrypted. The transceiver can unmute the speaker for the
length of time from approximately 180 ms to 360 ms. The transceiver determines whether or not the received signal is
encrypted after the transceiver completes unmuting the speaker.
If no signal is encrypted, the transceiver keeps unmuting the speaker.
If the signal is encrypted, the transceiver keeps unmuting the speaker after decrypting the received signal normally.
If the transceiver does not have information required for decryption, the transceiver determines that the encrypted signal
cannot be decrypted, and then mutes the speaker.
This function can be used to listen to the received audio even a little earlier. However, if the transceiver unmutes the
speaker prior to validating the received data, noises may be audible; hence, extra caution is required for this configuration.
