HT81x User Guide

“Device not registered”

This prompt will be played immediately after off hook If

the device is not register and the option “Outgoing Call

without Registration” is in NO

Five success tips when using the voice prompt

 “*” shifts down to the next menu option and “#” returns to the main menu

 “9” functions as the ENTER key in many cases to confirm or toggle an option.

 All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP

address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26

should be key in like 192168000026. No decimal is needed).

 Key entry cannot be deleted but the phone may prompt error once it is detected.

Note: Please make sure to reboot the device after changing network settings (IP Address, Gateway,

Subnet…) to apply the new configuration.
