4.0 out of 5 stars Great product, useless manual, 22 Jun 2012
Verified Purchase(What is this?)
This review is from: RTX Wireless Phone Jack (Office Product)
This is a very useful product which has solved a problem for us, but it is let down by poor instructions. Some are written awkwardly, and some are just missing. To avoid headaches for others I'll try to document what I worked out with a combination of the manual, their website, prior knowledge and experimentation:

* The UK version comes supplied with the necessary dongles to adapt British phones to the RJ11 sockets. Use these with the supplied leads rather than ones you have lying around as not all RJ11 plugs are wired the same way. As supplied it works fine with old-school phones with mechanical ringers (e.g. Wild & Wolf Series 302 Desk Phone). No extra adapter is required.

* DECT can't carry ADSL in any configuration. Connect the base unit to the filtered (phone) side of your microfilter if you have one. If you want to get your broadband to some other place in the house without wiring you don't need this product, you need a wireless router. If your ADSL modem/router has an ethernet port (as most do) then you can plug in one of these: TP Link TL-WR702N 150Mbps Wireless N Nano Router

* The two sockets on the base unit appear to be wired in parallel. You can plug your master/emergency phone into it, and it will still work even in a power cut. This phone will ring before the others do (which is a limitation of the technology).

* The base unit comes already paired to the extension. If for some reason you need to unpair them you can do a hard reset: Unplug any leads from the base and turn off the power. Wait a few seconds. Flick it on-off EIGHT (8) times (waiting for the light to go off each time) and finally back on. The light should flicker to indicate a successful reset. Follow the same procedure with the extension(s), but cycle FIVE (5) times. It might take a few tries; at least it did for me, as I have difficulty operating switches.

* There's a switch on the extension unit. Set it to 'S' (Speech) if you're going to plug a phone into it, or 'C' (Computer) for a modem or fax machine. You can still take and place voice calls in modem mode but there will be a burst of noise on the line before you get a dialtone.

* The base supports up to 4 extensions. The relevant product is RTX Wireless Phone Jack Slave. To pair with a new extension (or the original one if you've unpaired it): Turn both units off. Disconnect the phone line and connect a lead directly between the base and the extension. Turn on the base. Wait a moment. Turn on the extension. The light on the extension will start red, then turn either yellow or green on a successful pairing. The colour merely indicates which mode you've set the switch to.

* The base supports using a DECT/GAP handset directly as an extension. The pairing procedure is similar to the reset: Unplug any leads from the base and turn off the power. Wait a few seconds. Flick it on-off FIVE (5) times and finally back on. If you're successful the light will flash quickly. Now do whatever your handset requires to register to a DECT base station. Mine prompted for a pin. I tried 0000, 1111 and 1234. I can't remember which one worked but it doesn't take long to try. Feel free to leave a comment with the right answer :) You need to complete the registration before the light stops flashing. For reference, I'm using one of these: BT Diverse 7200 Dect Cordless Additional Handset.

* Hitting the Intercom button on the DECT handset rings the other voice extensions, which is useful. It doesn't ring the master phone or any extensions set to 'C'. GAP features not directly related to placing calls don't work.

* It doesn't appear possible to "butt in" to a call (party line style) except from the master phone. Whether this is a good thing depends on your needs.

I think I've got that all right. If there's any minor errors please do point them out so that this otherwise very good product is actually documented somewhere.
