2.2.1 Function (F) / Backlight ( )
NOTE - Secondary functions are only available on scanning versions of
the VHF.
Several of the keys have secondary functions in addition to the
main function. These are accessed by pressing F, then the
appropriate key within two seconds (do not hold the F key
down). When F is pressed, the F legend will appear on the
LCD for the two seconds it is active. Pressing another key
within this time will access its second function.
Backlighting
The LCD backlighting is switched on and off as a secondary
function of the F key. To turn the backlighting on/off press F
twice (Fig 2.2). If the F key is held down the second press, the
lighting will step through five brightness levels. Release the
key when the desired lighting level is reached.

2.1 Location of Controls
The RT62 and RT64 VHFs are very simple to operate, using
only five buttons and three rotary knobs to access a variety of
functions. The functions available will depend on whether the
radio is a scanning or non-scanning version (scanning func-
tions are not permitted in certain countries).
