Cellular (LTE) connection. If there is no cellular (or WiFi) connection, the radio will not be able to contact the PoC server. For cellular settings, please refer to the following page: DN: DN495 cellular connection – check list
WiFi connection. If there is no WiFi connection (or cellular), the radio will not be able to contact the server. For wifi settings, please refer to the following page: https://faq.entel.co.uk/2020/11/20/dn-dn495-425-wifi-configuration/ DN: WiFi connection
User Settings. Some user settings have a direct impact on how the radio connects to the server. Please refer to the following page for more details: https://faq.entel.co.uk/2020/11/20/dnuser-settings/ DN:User Settings
Self-Test. This can provide a quick check of some basic functionality, including the tilt sensor. https://faq.entel.co.uk/2020/11/20/dn-self-test-including-man-down-sensor/ DN: Self Test (including Man Down Sensor)
Server Settings. The PoC server user account for the radio may be missing or invalid. This can happen if the radio is being moved from an existing server to a different server where there is no corresponding user account, or if the username or password for that account does not match the radio settings. A DN radio that is moved to a server that has no matching user account may be become blocked, which then must be cleared from the Blocked Clients List (BCL) in T.Commander. https://faq.entel.co.uk/2020/11/24/dn-blocked-clients-list-bcl/ DN: Blocked Clients List (BCL)
Radio Re-boot (Cold Boot). If the operating system has become corrupted for any reason, a cold boot could resolve a connection problem. Switching the radio off using the on/off volume switch does not completely shut down the radio, instead it stays in a low power state. This is convenient because restarting the radio from this state is much quicker (referred to as ‘warm boot’) than loading all the software from scratch. However, sometimes it may be necessary to perform a ‘cold boot’ by removing the battery from the radio before switching it back on.
