11.5.2 Troubleshooting
No 2H Lock during Firmware Download
During a firmware download all other functions are temporarily suspended.
• Do not attempt to initiate 2H Lock mode select amplifier for gradient shimming or any
diagnostic mode during download.
Firmware Download Takes too Long
If the firmware download takes much longer than 5 minutes the Service Web message log
configuration may be amiss.
• Check Service Web Service | Log Configuration that the setting for Log Specific Info:
SSRB communication to slave units is set to Off (default).
Without this setting all communication to the L-TRX is logged in detail which extends the
download time indefinitely.
Missing Reference Clock
The reference clock is vital to most operations of the L-TRX. The clock is generated by the
AV4 REFERENCE board. SSRB communication with the ELCB is possible without reference
clock.
In case of a missing reference clock the PWR/CLK LED is deactivated.
• Check the clock wiring and the AV4 REFERENCE board for correct operation.
