tI' Talk Range
The IC-4008A is designed to maximize performance
and im-
prove transmission
range in the field.
However, the single
most important
factor in transmit
range (talk power) is your
surrounding
environment.
These radios are "line of sight" ra-
dios and as such, transmission
range is influenced by the de-
gree to which you can "see" the other communicating
party.
Large concrete structures
and heavy foliage or transmission
from inside a building or vehicle will reduce your talk power.
. Optimal range: wide, open areas free of obstructions. (up to
2 miles)
. Medium range: large buildings or trees blocking your line of
sight.
. Minimum range: mountainous areas or areas of heavy fo-
liage.

RING FUNCTION
The ring function has an answer back feature. This allows you to
confirm whether or not a call has reached the receiving party even
if the operator is temporarily away from the transceiver. (This func-
tion available between IC-4008As only.)
CDSet the same group channel number for
all of your group transceivers. (See left.)
