The flash time depends on your telephone exchange or host PBX. You can select the following
flash times: "80, 90, 100, 110, 200, 250, 300, 400, 600, 700 ms (milliseconds)". Your phone comes
from the factory set to "600 ms".
Make sure that a call is not put on hold.
- If you are connected via a PBX, a longer flash time may be
necessary to use PBX functions (transferring a call, etc.). Consult
your PBX installer for the correct setting.
5.3. Setting the Pin Code
A 4-digit Pin Code (Personal Identification Number) prevents unauthorized persons from using
your unit. The Pin Code is required for the dial lock and call restriction to be set or canceled.
The factory preset Pin code is "1111".
Make sure that a call is not put on hold.
