Vox (Voice Operated Transmit); Emergency Alarm; Battery Saver; Battery Low Alert - Baofeng BF-888S Manual

* VOX (Voice Operated Transmit)

VOX eliminates the need for using the PTT
key to transmit. The transmitter is keyed
when the VOX circuit senses you are
speaking into the microphone.
• When operating the VOX function, set
the VOX Gain level to recognize the
desired sound level (via software).
• If level is too sensitive, the transceiver
will key with noise in the background.
• If level is not sensitive enough, it will
not pick up your voice. Set level for
smooth transmission.
• On channel 1-5, Press and Hold the PTT
and MONI buttons while switching ON
the transceiver to turn the VOX ON or
OFF.

* EMERGENCY ALARM

On channel 11, Press and Hold the PTT and
MONI buttons while switching ON the
transceiver to turn the Alarm Function ON
or OFF.
This is a function for your receiver only.
You will not transmit the alarm on the
channel.

* BATTERY SAVER

This mode reduces power consumption
when not receiving a signal. Battery saver
turns on automatically 10 seconds after no
signal is received and no operation is being
performed.

BATTERY LOW ALERT

Reminds you that battery needs recharging.
Alert tone will sound and
blink.
* - Indicates that feature can be enabled and programmed through the CHIRP
or Baofeng software.
MONITOR
When no signal is being received, Press and
Hold the MONI. This is helpful for adjusting
volume level and receiving weak signals.
1750 Hz Tone: Pressing the MONI button
after pressing the PTT will send a 1750Hz
tone over the air.
* BUSY CHANNEL LOCK-OUT (BCL)
BCL prevents you from transmitting on a
channel if a signal is present. Pressing the
PTT switch while a channel is in use will
emit an alert tone and inhibit the transmitter.

* BEEP TONE

If turned on, radio will give short tone to
indicate that there is nothing programmed
for that channel.

* CTCSS/DCS Squelch filtering

CTCSS (Continuous Tone Coded Squelch
System) or DCS (Digital Coded Squelch).
You may sometimes want to hear calls only
from specific persons or groups. This option
allows you to ignore unwanted calls from
others on the same frequency. These tones
are sub-audible (cannot be heard) and are
selectable via software.
Note: These tones do NOT cause your
conversation to be private or scrambled. It
only relieves you from listening to unwanted
conversations.
