Product Details

Product Description

Product Description
BelFone long talk range analog radio BF-7110 comes with a tensile antenna to further extend the communication coverage. Its robust body and rich features both serve to make it an ideal choice for security workers, construction sites and many more fields of work.
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 Levels (0-9)
This feature helps to reduce background noise and deliver a clearer audio. The user can set the squelch level according to his communication needs.
Channel Announcement
When the user is switching channels using the channel knob, the radio will announce the current channel number. The user can choose from Chinese and English announcements, or he can turn off this feature if he doesn't need it.
TOT (Timeout Timer)
This can effectively prevent a channel from being unnecessarily occupied by mis-operation. 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.
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-7110 will only scan preset channels.
High/low Power Switchable
The user can switch between high and low transmitting powers (H: 7W L: 1W ). This makes BF-7110 more flexible and can extend the battery standby time when high power is not needed.
Programmable Bandwidth
BF-7110 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.
Busy Channel Lockout (BCL)
When activated, this feature prevents the radio to receive unauthorized signals or transmit signals to busy channels. So channels can be kept from unnecessary interference.
QT/DQT
The user can only receive signals programmed with the same QT/DQT code, which can effectively keep off unwanted signals.
Low Battery Alert
When the user turns on BF-7110, the radio will automatically run a battery check. When the voltage is lower than 3.3V, the LED will flash red and a warning tone will go off every other ten seconds. The user will find the radio unable to transmit. Please recharge your battery A.S.A.P.
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.
