Thank you Dan for your information.
"make sure the Nicad battery has not leaked and damaged the circuit board."
Sorry I don't follow. This unit have a batery inside?
It has a Nicad battery to back up the settings. It is an epoxy encapsulated thing, yellow with white printed label, about 3 x 5 cm, visible on one of the boards when you remove the case. It has two or three button cells in it and can be replicated easily enough with NiMH cells and then will not leak in the future.
My Thomson TRC 310 have two pins with 15 V Pos and the other with 15 V Neg. Would this work?
I have used these with both 12V and 24 V Racals, so presumably 15 V is fine.
I know that almost all British radios uses a 300 OHms audio accesories. When you refer to audio levels is because of this?
This unit is for the PRM-4031 family of radios?
It matches those in appearance yes. I have used it with both the TRA931 and 967. Fishermen use it with presumably standard marine VHF radios, Narco trafficantes, I have no idea, but they can also be used with telephones and fax machines.
Pin B should be power in?
Patricio, I am pretty sure the manual is available for download somewhere on line, have you searched for it? In any case the plug wiring is the standard Racal audio one, but I don't have my books to hand.
