Product Description
This feature-rich analog two-way radio comes with a numeric keypad and an HD LCD display, delivering more efficiency and safety to your radio communication. BF-3111 is a cost-effective choice for hotels, malls, transportation and many other professional users.
PC Programming
The user can program BF-3111 according to his communication needs on a PC via a programming cable.
Monitor
The user can use this feature to pick up weak signals on a channel. When there is no radio signals on the current channel, the user can adjust the radio volume according to the volume of the background noise.
Scan
This enables the user to monitor all the radio communications on the preset channels. The user can stop at any channel he wants. BF-3111 will only scan preset channels.
VOX
This function helps you to enjoy the hand-free operation. You can transmit via your voice while your hands are doing more important things. (It needs to be used with a paired accessory.)
Squelch Level (0-9)
This feature helps to reduce background noise and deliver clearer audio. The user can set the squelch level according to his communication needs.
TOT (Time-out Timer)
This can effectively prevent a channel from being unnecessarily occupied by misoperation. The user can set a timeout for each transmission. When the time is out, the transmitting will automatically stop and a warning tone will go off.
Programmable Bandwidth
BF-3111 supports both wide (25kHz) and narrow (12.5kHz) bands. The user can set the bandwidth via the PC programming software according to his communication needs.
Low Battery Alert
When the battery runs low, BF-3111 will give a warning and the user should recharge the radio A.S.A.P.
Busy Channel Lockout (BCL)
When activated, this feature prevents the radio from receiving unauthorized signals or transmitting signals to busy channels. So channels can be kept from unnecessary interference.
Auto Battery Save
When BF-3111 is not receiving signals and there are no other operations, it will go into battery save mode to save energy and extend radio standby time.
CTCSS/CDCSS
This also helps to keep out unwanted signals and deliver more channel clarity and efficiency.
Frequency Reverse
The user can reverse the frequencies of the transmitter and receiver, together with the respective CTCSS/CDCSS if there is any. The screen will display "R" when this function is activated.
FM Radio
BF-3111 can be used as an FM radio. When this feature is activated, the user can listen to the radio for recreation.
Built-in Torchlight
The integrated torchlight keeps the darkness at bay. This can be especially helpful when the user is working in a dark environment.
Battery Status
This enables the user to access the battery status at any time.
