Charge the battery pack before using it. The
new or stored (more than 2 months) battery
pack cannot reach full capacity after the first
charge. After 2 or 3 charges and discharges,
it will reach full charge.
1. Plug adapter into electrical socket.
2. Insert transceiver or battery into the
charging tray.
3. Ensure that the battery contacts connect
with the drop-in charging tray. While
charging is taking place, the LED will glow
Red.
4. After 3 hours charging, the LED indicator
will light Green.
5. Remove battery or transceiver from the
charging tray.
Asterisk [ * ] designates function changed via
software
*SQUELCH LEVEL
The purpose of the Squelch is to mute the speaker
when no signals are present. With the squelch
correctly set, you will only hear sound when a
signal is present.
*TIME-OUT TIMER (TOT)
The TOT limits the length of a users transmission.
The purpose of the TOT is to prevent transmitting
for a long period of time, causing thermal damage
to the radio. And alert will sound when the limit for
that transmission has been reached.
*SCANNING
Scanning is used for hands off monitoring of your
favorite frequencies. When the transceiver options
are set to SCAN (via software), setting the channel
selector to channel 16 directs the radio to scan the
selected channels from 1-16.
1. Transceiver stops scanning when a signal is
detected and continues when signal is gone.
2. If there are less than 2 channels, it cannot scan.

3. On channel 16, Press and Hold the PTT and
MONI buttons while switching ON the transceiver
to turn the Scanning ON or OFF.
4. If FM Radio function is activated via software,
the radio will not scan. Note: There is no actual FM
Radio function in this radio, so this option should
always remain deactivated in software.
*BEAT SHIFT / SCRAMBLER (not available
on some BF888S)
1. This option activates Voice Inversion.
2. When set, radios will no longer TX/RX normal
audio on the selected channel.
3. All radios in the group must have the option set
on the same channel to function properly between
radios.
Baofeng Disclaimer: On the back of model BF888S
aluminum case there is a “K” tag or an “UPDATE”
tag. Any colored tags are just for the
manufacturer’s internal use. They are only used as
a distinguishing mark for different suppliers. There
is no other practical significance and they are
unrelated to the scrambler. Baofeng Disclaimer
Check your country's regulations regarding the use
of scrambled transmissions.
*VOICE PROMPT
1. VP can be set ON/OFF via software.
2. On channel 10, Press and Hold the PTT and
MONI buttons while switching ON the transceiver
to also Activate or Deactivate Voice Prompt.
3. On channel 15, Press and Hold the PTT and
MONI buttons while switching ON the transceiver
to change Voice Prompt Language (CHI / ENG)
4. Any channel 1-16, Press and Hold MONI only
while switching ON the transceiver will Deactivate
Voice Prompt for that session only.
*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.
1. When operating the VOX function, set the VOX
Gain level to recognize the desired sound level.
2. If level is too sensitive, transceiver will key with
noise in the background.

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.

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.

conversation to be private or scrambled. It only
relieves you from listening to unwanted
