- What is Bluetooth Wireless Technology?
- Bluetooth Wireless Technology is a short-range communications technology using encryption for high security data/voice transmission.
- Is it safe to use Bluetooth devices? I have heard they can allow connections to my phone?
- For Bluetooth security reasons, once you have set up your Bluetooth devices we recommend setting the visibility option
in the Bluetooth menu of your phone to off so that other Bluetooth users cannot see the your phone.
This advice only applies to a few mainly older Bluetooth-enabled phones. Most new phones have better security.
- Can somebody else take control of my BlueAnt device if they are in range?
- No, your BlueAnt device can only connect to previously paired devices that have been authenticated.
The pairing procedure generates an encrypted key that is known only to the two paired devices.
- What is the difference between the Handsfree and Headset Bluetooth Profiles?
- The Handsfree and Headset Profiles are specifications for communication
between Bluetooth devices.
The Handsfree Profile is the one more commonly used to allow mobile phones to communicate with Bluetooth
headsets and car kits.
The Handsfree Profile provides the ability to carry out basic functions such as answering, rejecting and
ending calls, and adjusting
the call audio volume, as well as more advanced features like using the phone's voice dial functionality.
The Headset Profile is a more basic profile. It provides the ability to carry out basic functions such as
answering, rejecting and ending calls, as well as adjusting the call audio volume.
- How do I know if my devices are connected?
- When Bluetooth is turned on, your phone will display a Bluetooth symbol on the main screen. When your phone
is connected to a Bluetooth device, this symbol will change slightly to indicate that this is the case.
Some phones show a headset or a car symbol to notify you that they are connected to a Bluetooth device.
- How far can my mobile phone be from my BlueAnt device and still remain connected?
- Your BlueAnt device will remain connected within a range of 10 metres (30 feet), although please note that the
sound quality may start to deteriorate when your phone is more than about 7 metres (23 feet) away from the headset,
depending on your environment.
- Can other electrical devices cause interference with Bluetooth?
- Bluetooth technology employs a technique called frequency hopping. This means that Bluetooth devices
constantly change the frequency at which they send data, reducing interference with wireless devices like
wireless LANs and cordless landline phones.
Noise Interference can occur if the Bluetooth device is used in close proximity with a microwave.
If you are experiencing problems with your BlueAnt device, check if there are any such devices in
the surroundings, and if so keep the distance between the microwave and your BlueAnt device
to at least 5 to 10 metres.
Any interference will usually only cause a slight crackling sound. The frequency of Bluetooth is much
higher than that of radio station bands.
- If I cup my hand over a Bluetooth device the signal strength and quality suffers. Why does this happen?
- Bluetooth signals are radio waves and so do not need "line of sight" to operate. However, radio waves
cannot travel through water and as the human body is made up of mostly water they cannot travel through it.
Therefore, your hand will create a barrier causing slight interference and a loss of signal quality.
- How do I connect two Interphones in intercom mode?
- To use the intercom mode, you need to pair the two Interphones. To do this, turn both units off, then press and hold the Multi-Function Button (MFB) on each device for about 8 seconds, until the lights start to flash red and blue.
Then press and release the MFB on one of the Interphones. The lights on the Interphone F4 will turn solid blue.
You can also connect an Interphone F4 to the original Interphone in intercom mode. The pairing process is the same, except that
the light on the original Interphone will rapidly flash blue to indicate that the pairing is complete.
- Why doesn't the intercom work when I turn my Interphone back on?
- When the Interphone is switched back on, it will attempt to reconnect back to your mobile phone by default. To switch back to intercom mode, press and hold the Multi-Function Button (MFB) on one of the Interphones for about 3 seconds until you hear the second beep.
- Why does the battery life of my Interphone F4 not match the specifications?
- The battery life listed in the device specifications is indicative, based on typical usage of the different
features of the device. Some features use more power than others, so your actual usage may vary from the specification.
During intercom communication, one of the two Interphone devices has a greater battery consumption than the other, so
will require charging more quickly. Due to the increased battery usage required in intercom mode, you are recommended to enable the
intercom only when you want to communicate, with the devices in standby mode when you are not actually communicating.
- Why is the sound on my BlueAnt device noisy and distorted?
- You may have the volume too high. Turn the volume down on your BlueAnt device to a level that does not give echo or feedback.
You should also turn the volume down on your phone.
This issue can also be caused by a low battery, so you should charge your BlueAnt device and see if this resolves the problem.
Another possible cause is if your phone's ringtone is set to play very loudly, as this can cause distortion when
played through your BlueAnt device. In your phone, set up a profile with lower ringing volumes and keypad tones
and activate this profile for use with your BlueAnt device. See your phone's user manual for instructions on
setting up profiles.
Alternatively, you may have low antenna strength from your phone network which may cause signal drop outs or disruption.
- Why can't I hear any sound from the Speaker?
- The phone's memory may have become corrupt. This can be fixed by rebooting the phone (turn your phone off and remove the battery for a few seconds, then replace the battery and turn it back on again). If this does not resolve the issue, delete the pairing information for your BlueAnt device and pair it with your phone again.
- My BlueAnt device worked great but now it won't connect. What can I do?
- As newer phones are like small computers, they may become corrupt over time and you may need to reset them every so often.
Simply turn your phone off and remove the battery for a few seconds, then replace the battery and turn it back on again.
If this does not resolve the issue, delete the pairing information for your BlueAnt device and pair it with your phone again.
- Why does the talk time and standby time not match the product specification?
- The talk time and standby time will be affected by a number of factors. For example, different phone models
draw different amounts of power.
- Why does my phone's battery not last as long as it used to?
- When you switch Bluetooth on, your phone searches for Bluetooth devices in the area. This will use more battery power than without Bluetooth on. Your BlueAnt device has a standby mode it enters when connected to your phone so that it minimises battery loss. This allows your BlueAnt device to have such outstanding battery life as well as reducing the power required by the phone.
- My phone says "Bluetooth Module not found". What can I do?
- This means that your phone cannot find its internal Bluetooth chip for some reason. Restarting your phone should fix this problem. If not please contact your phone manufacturer for assistance.
- I am having trouble pairing a second phone. What can I do?
- When Pairing a second mobile phone, make sure the first is off or out of range.
If you cannot connect to a previously paired and connected phone, go to the Bluetooth menu in the phone, select your BlueAnt device and press Connect. Some phones may require you to connect manually in this way if this is the second device used.
- How can I stay near my BlueAnt device but not have calls diverted through it?
- Your BlueAnt device will remain connected within a range of 10 metres. If you want to take calls through the phone simply switch your BlueAnt device off.
- I have a PDA phone that pairs to my BlueAnt device but has trouble transferring calls. How can I fix this?
- Go to the phone manufacturer's website and download and install the latest software for your device. Many new PDA phones are software upgradeable and fixes are made available for problems such as this. This is especially the case with newer devices.
- Phone commands (the phone's inbuilt voice dialling feature) are not successful every time. What can I do?
- Using your headset to record the voice tags can enhance the recognition rate. Please refer to your phone's manual for more information about recording voice tags.
Noisy environments can also affect the voice recognition. Record your voice commands in a quiet environment.
