  Cobra Lynx BT215Cobra PhoneLynx


The PhoneLynx connects your Bluetooth-enabled hand-held cell phone to any conventional telephone or PBX system with a simple RJ11 modular phone cable. Up to 2 cell phones can share this unit, but both connect to the single telephone jack, one call at a time. Call waiting is enabled to allow switching between calls on the same or different phones. Caller ID is passed through. 12 vdc operation with AC power supply included. Order model BT215.    $39

 

Note: Not all cellular telephones are Bluetooth enabled. Check yours before ordering this unit.

 

 How They Work 


Cell phone docking stations let you use a regular hand-held cell phone to provide dial tone to one of our field deployable telephone systems. They provide conventional dialtone and ringing signals to the telephone system’s incoming line jack. This allows multiple users to share a cellular phone line with regular phones at their own desks.

 Docking stations connect to your handheld cell phone with a wireless Bluetooth signal. Bluetooth capability permits the use of many different cellphones, and changing phones is quick and easy. You can still connect your cell phone to its charger while in use to avoid dead batteries when you need it the most. Even if you have other dial tone sources, a docking station makes a great resource tool to keep in the kit.

 

Docking stations have both advantages and disadvantages

for disaster & emergency telephone service 

Advantages


Docking stations allow you to use the same Bluetooth-enabled handheld cell phones your agency issues for everyday use, without the additional monthly service charges associated with dedicated cellular base station terminals like our SX5. The purchase cost of a docking station is also significantly lower than a dedicated cellular telephone terminal.

 

Disadvantages


Handheld cell phones only work well in locations with good cellular signal strength. If you will be working inside a metal-skinned trailer, vehicle, or building, we recommend that you perform signal strength tests with the cell phone you to plan to use before purchasing the docking station. It may be necessary to install an “in-building” signal booster with an external antenna. 

(Our SX5 1-line and GFX44 GSM 4-line cellular telephone terminals with external antennas will work better than most hand-held phones in weak signal areas.)

 At this time, no brand of docking station supports fax or computer connections due to limitations in the cell phones themselves.

 Many hand-held cell phones are not designed for continuous duty operation and may fail when you need them most. If you anticipate a heavy call volume or long calls, (likely during an emergency) you should consider using a cellular base station instead.
