10-18 5300 ES Series Mobile Radio Operating Manual March 2008
Secure Communication (Encryption)
Note
The radio will reset after a successful download in this mode, but the previous radio
profile will remain in use until the radio user or PC Configure operator activates the
OTAP parameter.
If the OTAP procedure is not successful, the radio will reboot and return to normal
operating mode with the current parameters.
10.7.2 OTAP Transfer Times
Larger files tie up the radio for a long time. Therefore, any user interface event, such as a
channel change, zone change, button press or toggle switch position change (portable
radios only) stops the OTAP procedure and returns the radio to normal operating mode.
For button presses/toggle switch position changes, the radio exits OTAP mode only if a
function is programmed for the button/toggle switch; otherwise, the bad tone sounds.
Low signal conditions may also cause the radio to exit OTAP. If the radio does not receive
a response from PC Configure one minute after receiving its last data packet, the radio
stops the OTAP procedure and returns to normal operating mode.
