The Emergency ‘E’ button may be configured to generate an 1850Hz tone that is used by some
emergency desks if fitted with the tone detector.
To program Emergency ‘E’ button to generate the tone:
Press and release the DA key to make the telephone go off hook.
Press the store button located on the main PCB (see figure 5). A short beep should be heard.
Press store button again. Again a short beep should be heard.
Finally press the Emergency ‘E’ button, the telephone will sound a longer beep indicating that the
1850 Hz tone has been restored.
6.2 FACTORY SETTINGS FOR DTMF.
All the configuration settings are achieved by changing the position of the jumper links located on
the main PCB which is inside the polyester telephone enclosure rear casing.
To prepare for installation, undo the three retaining screws shown to remove the front casing from
the rear. The screws are not captive in the front casing; a 5mm Allen key is required.
Note:
Do not remove the polyester telephone enclosure rear from the metallic surround as this is
not necessary.
Disconnect the ribbon cable at either the keypad PCB or the main PCB to prevent damage.
The A103 telephone is factory set to tone dialling (DTMF) as default (HD3 & HD4 set to the position as
shown below in Figure 3).

6.3 ASSEMBLY OF TELEPHONE ON TO INSTALLED BASE
Ensure that the keypad connection between the base and the keypad PCB is made observing the
correct orientation of the connector. A keyway on the connector facilitates ensuring that the ribbon
cable connector is correctly orientated. Do not forcibly fit the connectors
