If this feature is enabled, an unoccupied two way radio will automatically enter the
power save mode, i.e. making certain features in standby mode. After a certain
time or when a user presses any key, the two-way radio returns normal operation
and check if any incoming call in the channel. If it is not detected, the two-way radio
will return to power save mode, which will not only extend battery life (depending
on chemical property of the battery and its application condition), but also delay
response time.
It shall be noted that if this feature is enabled, for TX two-way radio, after the PTT key
is depressed, a call will be established with a slight time lag (within ms). For RX
two-way radio, it has lower possibility of correct synchronization in power save
mode, which may make delay more serious, thus resulting in loss of first-second
message transmitted by some audios when the two-way radio has poor RF.
Nevertheless, in a good RF coverage, this will not happen, but for extension of
battery life, the delay is negligible. Therefore, it is recommended to enable
power-save mode for all two-way radios.

Channel unoccupied indication
If this feature is enabled, you will hear a prompt tone after a voice call ends. You
will also hear a prompt tone when the voice call in the current channel is
interrupted (for example, an incoming impolite call from the two-way radio from the
third party or sending an emergency alarm). However, a voice call ends when the
calling party releases the PTT key irrespective of suspension time. This feature
will prompt the receiver with when to answer it before a voice call from the other
party ends to ensure a smooth talk.

Call allowed indication
The two-way radio sounds this prompt tone after the PTT key is pressed. After this,
the two-way radio can transmit it in the channel to prompt a user to start
