The LCD display shows all main parameters so no further menus are 
provided or required (except frequency setting detailed above). During 
normal operation, therefore, the menu buttons do not have 
any function. 
 
The following are LCD display fault indicators and their meaning: 
 

 TEMP!  

The system is running too hot and has shut down the RF 

output as a safety precaution. Check the fans for correct 
operation. Also check the antenna system, including all cabling 
(and/or filters and/or combiners where fitted) for correct 
operation. The FWD! indicator (see below) will also show and the 
standby transmission system (where used) will have activated 
(TTL control). 
 

 REF!

! The system has detected a fault in the antenna system 

and has shut down the RF output as a safety precaution. Check 
the antenna system, including all cabling (and/or filters and/or 
combiners where fitted) for correct operation. The FWD! 
indicator (see below) will also show and the standby 
transmission system (where used) will have activated (TTL 
control). 
 

 FWD!  

The system has detected there is no forward power. This 

may be due to one or both of the above symptoms, due to a PLL 
failure, or due to excessive power setting. The standby 
transmission system (where used) will have activated (TTL 
control). 

 
Ensure air vents and internal air tunnels are kept free from dust during 
operation.
