- The default password for the Phonelabs Bluetooth Module is "3774". Bluetooth devices transmit and receive at approximately 1 milliwatt in the 2.4Ghz frequency spectrum. There can be interference issues with using any Bluetooth device in the same area as 2.4Ghz cordless phones, hybrid 5.8 Ghz cordless phones, and WiFi 802.11b/g/n, which also operates on the 2.4Ghz frequency, but at much higher (400 milliwatts or higher) power. For best results when using other 2.4Ghz devices, keep those devices as far away as possible from the Dock-N-Talk™ equipment and cell phone when you are using the Bluetooth module. If you are still having interference issues, try resetting the operating channel on your WiFi router to channel 11, or it's highest setting, and your cordless phones to the highest channel available. (Bluetooth operates on channel 1 or 2.) See your wireless router and cordless phone owner's manuals for instructions on resetting the operating channels.

Phone Labs is currently delivering the BT03-B Bluetooth Module which provides the Bluetooth Module (shown larger than life)latest Class 1 Bluetooth 2.0 advanced features and extended range (Class 1) of 300' or more. It is only supported by current Phonelabs equipment with firmware versions 1.47. Older firmware versions do not support this new Bluetooth Module. The maximum effective range of the early Bluetooth Module BT01 was 30 ft and for the BT03-B is 300 ft or more but can be less depending on enviromental conditions and the Bluetooth software in the connecting cell phone. Many of the new cell phones today will NOT work with the older Bluetooth Modules. You must use the BT03-B Bluetooth Module to use these new cell phones.

Important new features of the latest Bluetooth Module (BT03-B) allows the user to pair up to 8 phones to the same Bluetooth Module and is compatible with new voice compression technology that is currently being introduced. Sound Quality has been improved from earlier versions as well as greater ability to reject outside 2.4Ghz interference. This means that this module works well in enviroments that have WiFi, cordless phones, and other 2.4Ghz transmitters. As in older Bluetooth Modules, only one cell phone at a time can be actively connected to the Bluetooth Module. The new Bluetooth module can be identified by the model number of BT03-B on the back label. The Bluetooth Module has a "Flash" memory allowing it to remember paired phones if the power is disconnected or the module is stored for some time.

As stated above, former firmware versions (1.46 and below) of Phonelabs equipment are not compatible with the new BT03-B Bluetooth Module. However, all the original versions of the Bluetooth Modules (BT01) will continue to be compatible with the newest Phonelabs equipment firmware versions. If you own one of the older firmware versions of Phonelabs equipment and you want to use the new BT03-B Bluetooth Module, you will need to send your device to Phonelabs for a firmware upgrade to 1.47. The cost for this upgrade is $25 which also covers return shipping costs back to you. Contact Phonelabs directly for information on returning your device for the firmware upgrade.

If you are planning to use the Dock-N-Talk™ instead of a conventional telephone land-line with non-cellular commercial equipment (ie: irrigation pivots, pumps, meters, alarm systems, PBX, etc.) please be aware that CDMA systems (older Verizon, Sprint, Altell, Cellular One) do not pass DTMF tones (touch-tones) clearly through their networks. For this reason, it is highly recommended that you use a GSM (AT&T, T-Mobile) or LTE (new 4G Verizon & AT&T) system in order to interface with your commercial equipment as GSM and LTE transmission technology does not garble DTMF tones.

Lindsay Manufacturing Co., the manufacturer of Zimmatic center pivot and lateral move irrigation systems, upgraded their computer speech boards in 2006 to clear up the distorted DTMF tones sent through a CDMA network. You can use a CDMA carrier with the latest Zimmatic computer speech board from Lindsay. If your speech board is older than 2006, you must upgrade to this new speech board to use a CDMA carrier. Contact your local Zimmatic dealer for more information and pricing.

If you are wanting to use the Dock-N-Talk™ with more than 5 or 6 wired phones, I can supply you with a "Ring Booster" that will increase the 3 REN (Ringer Equivalency Number) of the Dock-N-Talk™ to 15 REN allowing the your unit to ring up to 15 phones.

Phonelabs interface equipment does not boost cellular signals. Voice quality and proper operation of your Phonelabs interface equipment is dependent on the signal quality of your cell phone reaching the nearest cell site. Many inside locations may not require an external antenna for your cell phone to work properly. If your cell phone works well at the location where the Phonelabs interface equipment will be placed (3 or 4 bars or upper 3/4 or higher on the phone's signal strength meter) then you don't need an external antenna. With marginal signal strength at the planned location ( 2 bars or middle of the meter) you should purchase an external antenna for best performance. A low signal strength (1 bar or 1/4 or lower part of the meter) indicates the absolute need for an inside repeater system. You should also try different indoor locations to see if any of those locations improves the cell phone's signal strength before deciding on purchasing an external antenna or repeater system. I supply a variety of antenna connectors, adapters, external antennas (including Yagi's), low-loss cables, and signal boosters depending on your needs and type of cellular service.
