Coverage/Range
The maximum range depends on terrain condition and is obtained during use in an open space. The only limitation to
maximum possible range are environmental factors such as blockage caused by trees, buildings, or other obstructions.
Inside a car or a metallic constructions, the range can be reduced. Normally the coverage in the city, with buildings or
other obstructions is about 1 or 2 Km. In open space but with obstructions like trees, leaves or houses the maximum
possible range is about 4-8 Km. In open space, without obstructions and in sight, like for example in mountain, the
coverage can be more than 10Km.
Battery recharge
BF-88A is equipped for using a 3.7V Li-ion rechargeable battery pack which can be recharged connecting the socket of the
AC/DC wall adaptor to a mains power socket and inserting the jack of the wall adaptor into the desktop charger plug. It
takes 4-5 hours to fully recharge the radio. For maximum battery life, we recommend charging the battery pack when the
BF-88A is off and the battery pack is fully discharged.
Using a different battery charger other than the one specified can cause damage to your device or may even
cause explosions and personal injuries.
The Battery power saving feature enables a reduction in consumption of up to 50%. If it has been set, it automatically
activates when the transceiver does not receive any signal for more than 5 seconds in order to save the battery life.

Operations
Power on/off and volume adjustment
Rotate the Power/Volume knob clockwise to turn the radio on. Rotate the control clockwise /counter-clockwise to adjust
the volume level as you prefer. To turn the radio off, rotate the control counter-clockwise till hearing a mechanical “click”.
Transmission
To communicate, all radios in your group must be set to the same channel. Briefly press the Side key 1 to enable the
Monitor feature in order to make sure that the frequency is not busy, and then press the PTT button. Release the PTT key
to receive. Only one user at a time can talk during radio communications. Therefore, it is important not to transmit when
you are receiving a communication and use the transmission mode sparingly to allow other users to talk. Transmission
consumes a significant amount of energy and should therefore be used sparingly to prolong the battery life. If you are
unable to contact a station that you have no problems in receiving, the station may be using CTCSS tones or DCS codes.
Monitor
The Monitor feature is for excluding (opening) the Squelch, in order to listen to signals that are too weak to keep the
Squelch permanently opened. Hold down the Side key 1 to enable such function.
Scan
This function can be activated only by means of the optional programming software. To enable the Scan function, all 16
channels must be programmed. If you turn on the radio on channel 14, the scanning will automatically start. Whenever
any signal is detected, the scanning will stop on a busy channel. If the PTT is pressed, you will transmit on the latest busy
User Manual（FCC&IC）Draft
Model: BF-88A
channel. Channel 14 is the priority channel; therefore if you don’t pick up any signal when you press PTT, the radio will
transmit on channel 14.
CTCSS/DCS tones
CTCSS and DCS tones are similar to access codes and enable the radio to communicate only with the users that are tuned
on the same channel and have set the same code. For each channel, you can set up to 50 CTCSS tones and 210 DCS codes.
The CTCSS/DCS tones are a sort of “access codes” and enable the radio to communicate only with the other users set on
the same frequency and on the same CTCSS/DCS tone. Undesired signals coming from other stations set on the same
frequency but with different CTCSS/DCS tones won’t be received.
Flashlight
With BF-88A turned on, shortly press the Side key 2 to turn on/off the flashlight at the top side of the radio.
Prompt voice switch settings
The encoder is selected to the 10th channel. Press and hold the PTT and Side Key 1 to turn on the radio, and turn the
prompt voice on or off.
Turn on the prompt voice function, and there will be voice prompts when the encoder is turned on or operated. If you
turn off the prompt voice function, there is only a “beep” prompt when you turn on or operate the encoder.
