Revert radio settings to customisation settings
Users have the ability to add personal data to the radio, such as adding contacts to the phonebook,
changing the talkgroups and sending and receiving SDS/Status messages. Such changes may be
undesirable on fleet radios that have been specifically customised for fleet users—where radios are
not personal processions. Using the Revert All Changes option, the radio settings can be reset
back to the last customisation settings.
There is also a Revert Non-Personal Changes option that allows users to reset the radio settings
back to the last customisation, but keep their personal changes to the phonebook, talkgroups and
messages.
To revert the radio settings:
1. Select Menu>Options>Settings, then select the Revert User Changes option.
2. Select the option you require. Press the Select key.
