9）Access Authentication (only for repeater mode)
l In repeater mode, the operating mode of a digital two-way radio includes normal mode and
safe mode.
1. In normal mode, a handset only needs to send a connection signal to the repeater. After
successful connection, the repeater will enable a channel. After this, the handset can
communicate with other handsets to be communicated until the session is manually
disconnected or interrupted for timeout to release the repeater. Quick access communication
of a handset can be realized via this mode.
2. In safe mode, handset A sends a linking signal to be connected with the repeater first,
which will then send the linking signal to handset B. After connection, the repeater enables a
repeater channel and responds with a confirmation signal to handset A. Handset A can be
communicated with handset B normally.
10）Power-save Mode
l 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.
l 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.
11）All LED Disabled
l When the two-way radio is started and used, turn all indicators off. Irrespective of backlight
setting, all indicators are disabled (including backlight and start indicator)
n Voice Prompt
1）All mute
l When the two-way radio is enabled and used, turn off all prompt tones. Number reporting
feature is disabled irrespective of number reporting setting.
