HOOKFLASH (RECALL) PERIOD

Set the length of the hookflash signal. Three options are offered, 600mS, 200mS or 100mS.

The nominal flash signal length for the PSTN network in Australia is 100mS. (200mS in New Zealand)  

If your Touchfone Executive is connected to a PABX rather than the PSTN, you may need to use the front panel RECALL / FLASH button to transfer calls, or recall a local operator.  Consult your PABX documentation or serviceman to determine the correct signal length for your PABX.
