 WARNING: ITAR CONTROLLED INFORMATION

This release does not support the following:
 Upside-Down mounting
 Base Station Direction Finding

Resolved Issues


Erratic LOBs for UMTS MSDF – This issue only occurs when running UMTS MSDF after a
power-up, and does not occur if MSDF on another protocol (GSM, CDMA, LTE) is run prior to
UMTS. Most ArrowHead units will not exhibit this issue.

Known Issues
The following are known issues that were uncovered during the testing of this software release.
 Self Test – The Arrowhead self test is not fully populated. Status provided and displayed on the
PCC does not provide all self-test status.
 RF Overload Protection Indicator – The RF overload indicator does not show when the RF
overload condition happens. However, the protection circuit works as designed.
 Critical Temperature Indicator – When Arrowhead reaches the critical temperature,
Arrowhead shuts down but the Critical Temperature Indicator is not shown every time the
condition happens.
