MATRA 420 Manuel utilisateur

Key programming is typically managed by the Telephone Manager. However, it is possible to program customizable keys. Press the PROGRAMMING key, then the key to be programmed, select the desired programming type, enter the value corresponding to the service, and press the PROGRAMMING key again to validate. Common programming types include:

• Type 1: to save external and internal numbers.
• Type 3: to program a transmission of voice frequency codes (e.g., for voicemail).
• Type 4: to program the Intercom function: to display the status of a station, intercept calls, and allow direct calling.
• Type 5: to program the filtering function: to display the status of a station, intercept calls, and allow direct calling.
• Type 8: to save a code that provides access to a programmable service (e.g., filtering, forwarding, etc.).

According to the manual, the programming of keys or services on a phone is generally set by the Telephony Manager. However, some simpler functions are described in the document, allowing you to program certain customizable keys. To do this, press the PROGRAMMING key, then the key you want to program, indicate the type of programming you want, indicate the value corresponding to the service you want, and to validate, press the PROGRAMMING key again. The most used programming types are as follows:

• Type 1: saves external and internal numbers.
• Type 3: programs a voice frequency code transmission (to directly consult your voicemail, for example).
• Type 4: programs the Intercom function: visualization of the status of a phone, interception of calls intended for it, as well as direct calling of this phone.
• Type 5: programs the filtering function: visualization of the status of a phone, interception of calls intended for you or that are forwarded to the filtering phone or another forwarding phone, as well as direct calling of this phone.
• Type 8: saves a code that gives access to a programmable service (e.g., filtering, forwarding, etc.).
