Turning the meter off and on 

 

If the meter is powered by your transceiver power supply, it will simply go off when the transceiver goes 
off  and  come  on  again  when  the  transceiver  comes  on.  No  power  switching  of  the  meter  is  needed.  If 
however you are powering the meter from a source that is always on, you may wish to switch the meter 
off and on independently. The meter allows you to do this. To switch off, hold the button until the menu 
screen appears, then keep the button pressed until the “goodbye” screen appears, then release. To restart 
the meter, momentarily press the button. Interrupting the power supply will also restart the meter. 

 
 

Using the Menu 

 

The menu enables the operator to adjust the brightness of the display and to set-up the alarm parameters. 
To enter the menu, hold the button until the menu screen appears and then release immediately. Holding 
the button for longer causes the meter to turn off. 

 

This is followed by the help screen. It reminds you how the menu works. A quick press will move to the 
next  item.  A  long  press  will  change  the  displayed  item.  Note  that  the  help  screen  is  only  shown  once  in 
each session. 

 

The first menu item allows you to adjust the screen brightness in four stages to suit the ambient lighting in 
your shack. Brightness 1 is quite dim, rising to brightness 4, the brightest. 

 

 The high SWR warning and alarm screens are at full brightness and independent of the brightness setting. 
When the brightness number is at the desired level, a short press will skip to the next item. 

The second menu item turns on or off the high SWR alarm. When the meter leaves the factory, the alarm is 
turned off. If the alarm is not to be used, there are no further menu items and a short press will leave the 
menu.
