Technical Information We hope the following Sopho-K notes are helpful. Remember...safety first. The information on this page is provided as a service and we can accept no liability for those who use this information to maintain or modify a system. The Sopho-K range of systems (K8, K308, K12 K512, K24 K824) are now very old and it may be time to consider a replacement. Good reliable, low cost, easy to install systems are now available and can be seen by visiting the Phone Systems section Enough of that...let's talk about the Sopho K... To install the system you will need a 2/3A secondary line jack unit (wall-socket) for each terminal. The MDF (main distribution frame) has connection points A.B.C.D for each extension (terminal). The wiring from the MDF to the secondary socket is as follows. ISDN- Unfortunately the Sopho-K systems cannot be connected to ISDN lines. If you have a Sopho-K system, and need access to ISDN, we suggest you take a close look at the NEC XN120. Tone Dialling- The most common problem reported on the Sopho-K is that it is too slow when making external calls. This is usually because it is set up to dial in 'pulse' mode instead of 'tone'. The reason for this is that many of the systems were sold before the public exchanges could support tone dialling. To set it up correctly for tone dialling you have to remove the front cover on the Control Panel. Switch 1 (relates to Line 1). 4 (relates to line 2), 7 (relates to line 3), 10 (relates to line 4) and 13 (relates to line 5 ) should be in the up position. Remove power before setting this up and if you have any doubt at all give us a call. Because this needs to be done in the Control Unit...I must point out that we do not accept any liability for problems so be very careful. Attached to a larger system- The Sopho K range can be connected to larger systems. For example the K308 (K8) equipped with K365 terminals makes an ideal manager/secretary. You simple wire connect one of the exchange lines to an extension port on the larger system. Switches inside the Control Unit can be changed to configure the exchange line port to accept earth or timed break recall. If you want some help with this let us know what type of system you have and tell us the 12 digit part number that will be found at the base of the unit. Self Test- You can run a simple self test for the terminals by holding down the * and hold key when you plug the set in. If it has a display it will tell you the terminal type. All of the LED's will flash. Press keys in the following order, soft keys 16-1,keypad 1-9, *,0,#, function keys recall, transmit, program, hold, go off-hook sounder is activated, go on hook. Programming-Far too many programming options are available for us to mention here. Unfortunately, we do not have authority to copy the Supervisor's Programming Guide. But...if you have any specific problems, give us a call and we may be able to help. Power Fail- In the event of Power failure, Power Fail MDFs switch exchange lines direct to an independent circuit. Ordinary telephone sets are then connected via master line jack units. Headsets- Two special terminals were released that included amplifiers and a connection for a headset. These were known as the K365(H) and the K261 (H). Sopho-K Feature Codes Many of our customers already have Sopho-K systems but have lost their User Guides and forgotten some of the most common feature codes.
