About the hand-held control head (HHCH)
Your radio may have a hand-held control head
installed, to enable you to operate the radio at a
distance from the radio body.
The keys and controls work in the same way as those
on the standard control head, with the exception of the
volume up and down keys. The hand-held control
head also has two additional function keys.
