TROUBLESHOOTING

Bypass TEMP: (as seen on the TFT display)

The LA-1K is in 

BYPASS

 to protect itself from high temperatures.  The 

temperature will show in red when it exceeds 70°C.  When the heatsink 
temperature exceeds 100°C 

BYPASS TEMP

 will show on the display.

Solution:

Allow time for the heatsink to cool down below 70°C.

Operate (OPR) will automatically return.  Verify that the side vents are 
clear from obstructions.

High SWR or prolonged transmission in carrier modes may cause 
elevated temperatures.

TX OVERDRIVE: (as seen on the TFT display)

This displays when the drive level exceeds approximately 60W.

Solution:

Reduce the drive level to prevent displaying this fault.

 Vd: (as seen on the TFT display)

The LA-1K is in 

BYPASS

 to protect from loss of +50V, drain voltage supply.  

The fault should clear in a few seconds.  This can occur when operating 
on 120V if the drain current (Id) exceeds 32A.

Solution:

Switch the supply voltage to 240VAC or if operating on 120VAC is desired, 
reduce drive power.

OPERATIONAL MODE

ANTENNA SELECT 

To switch antennas between ANT 1 (Coax 1), ANT 2 (Coax 2) and ANT 3 
(Coax 3) press the ANT button on the touch-screen display.  

Then select the desired antenna output.  This setting will automatically 
select when changing bands to the last one used on any particular band.  
The default value is ANT 1 (Coax 1).

Select the antenna by pressing the corresponding number on the 
touch-screen display.  A yellow arrow below the number of the antenna 
will indicate which antenna is selected.  Press EXIT to return to the main 
menu.
