Previous Edit and Immediately Dial Out

The HT95168 provides previous edit for dialing convenience and the maximum edit length is

32-digit, once off-hook or hand-free the edited number will be dialed out immediately. Besides,

pressing the [Call back/Redial] key or the [Add

¢0¢ Call back] key can also be dialed out directly.

Unauthorized-dialing Protection Setting

The meaning of [Unauthorized-dialing] is that the telephone line was illegally shunted by another

phone and making the line dial out.

· When the protection function is enabled, the HT95168 generates an interference signal to pro-

tect the line from being illegally used.

· At On-hook state, press the [#] key for 2 seconds, then turn on the LCD [Protection] icon to en-

able the protection function.

· Pressing again the [#] key for 2 seconds, turn off the icon to disable the function.

Note

The initial setting of this function is disabled.

To ensure that this function works normally for long distance conditions, fill-in or re-charge the bat-

tery.
