Nice phone. Would really love the Telecom Australia version of this model, came out here in 1987, called the Telecom Walkabout.
Wow, amazing diassembled photos, EPROM, button cells, filters, oscillators :-)
Hi Tailor & others.
I now have 2 of the Telecom Australia Walkabout phones, identical to this BT Roamer model.
But they are both faulty. They power on ok, but displays ERROR 2 immediately in the display.
They do not get past the initial boot up stage, the only button that works is the Power button.
Does anyone have any info about this error code ? A copy of the service manual would be great !
There are 2 small backup button cells in the phone, I wonder if it could be related to these ?
Tailor, does your phone power up ok, any error codes on yours ?
Sorry but i have nothing for you, both of mine power up fine and I don't have a service manual either.
The backup up buttons are interesting, that's definitely a possibility. Have you tried chucking a little voltage in them? I've had good success with dry cells this way, they won't last long but perhaps enough to eliminate it as a cause.
these backup-battery-button-cells might be a problem .
atleast on some ericsson phone , when cell is coroded and shortened phone went unstable ( random reboots, power offs etc )
Thanks guys. I have tried replacing the 2 button cells in one of my phones, but it did not help.
Same old error message still. Oh well. Cannot do more without a service manual.
