Chapter 4 Troubleshooting
4.1
Power-Up Errors
In the event that there is a setup problem while powering up the system, the system attempts to
notify the user of this problem by displaying power-up error messages as follows. The O7 Control
Head displays power-up errors occurring in either radio.
Any power-up failure during the self-check routine will cause the associated radio to generate a Bad
Key Tone.
4.1.1
Missing Radio
If one of the radios is not connected at power-up, an error message is displayed, and the remaining
radio continues to function. For example, when only the Primary Radio is connected, it will show
"Secondary missing", and when only the Secondary Radio is connected, it will show "Primary
missing".
NOTE: While only one Primary or Secondary Radio is connected, customer is not recommended to
rely on the radio, as its function shall be limited. In order to use the radio as a Standalone
Radio, it is required to change the "Radio Selection" field to "Standalone Radio".
4.1.2
Improper Radio Combinations
If both radios go through improper radio configuration setup, "FL 01-90" is displayed to indicate a
communication error with the control head has occurred. If the error cannot be recovered, the radio
keeps resetting before it enters the maintenance mode. See
details on codeplug configuration. The improper APX Dual-Radio setup can have any of the following
radio combination:
• two Primary Radios
• two Secondary Radios
• two Standalone Radios
• one Primary Radio with one Standalone Radio
• one Secondary Radio with one Standalone Radio
4.1.2.1 Secondary Radio FL 01-90 Scenarios
The first time a Secondary Radio is powered up without a Primary Radio attached, the Secondary
Radio will reconfigure itself to communicate directly with the O7 Control Head. During this process,
the control head will time out, displays a "FL 01/90" error message, and resets the radio. After the
reset, the radio will power up with full single-radio functionality, but will permanently display the
"Primary Missing" error message.
NOTE: The first time an APX Dual-Radio System is powered up, the Secondary Radio will
reconfigure itself to communicate indirectly with the O7 Control Head. During this process, the
control head will time out, displays a "FL 01/90" error message, and resets the radios. After
the reset, the Dual-Radio System will power up successfully.
