4. IF IT IS NOT wORkING:
NO PHONE CONNECTION:
- Check if the programming switch is set to 1.
- Check the connection by connecting the telephone direct to the main line.
- Check the power on the Trunk terminals (A, B; TRUNK, TRUNK). This must be the same as on the telephone line terminals (TEL).
NO CONTACT wITH THE SIMPLEBUS SySTEM:
- Direct after programming the Simplebus code, the LED shows the status of the bus line. If the LED blinks 4 times, measure than the power between the bus line terminals
(L - L). (This must be between 17 and 30VDC).
- Did you program the right code? If any doubt, please follow the programming procedure mentioned in chapter 2.
- If the telephone rings, but you are not able to speak, it could be that the interface, the reason could be the programmed bus mode in the interface. This could happen if you
forgot to program the interface, while in the programming procedure the bus type automatically will be adapted. Please follow the programming procedure of chapter 2.
NO DIvERSION:
- Be sure that the number of the diversion has been programmed properly. If the interface is connected to a telephone switchboard (PABX), normally there must be programmed
a "0". For some switchboards it could be necessary to program a pause after the first number, by adding ## (wait after each # for an acknowledge).
5. SETTINGS OF THE INTERFACE: In the table below you find the default settings of the telephone interface.

L
Keep local phone ringing, while "special follow me with call
M waiting"started (see point C)
N Reset to factory settings
* If you use this function, you also must setup the Simplebus mode (dafault SB1). If address 000 is programmed, the interface will activate on all codes.
If the system is working fine, but it is desired to change the factory settings, please follow the instructions below:
Important: An analogue telephone must be connected to the output of the telephone interface.
1 Set the programming dipswitch to the position "ON".
2 Choose between on of the codes mentioned in the table followed by the required setting.
Example: setting internal call time to 40 sec. (line 2) choose:
3 Set the programming dipswitch to the position "1" to enter into the normal mode.
