tant factor in transmit range (talk power) is the surrounding envi-
ronment. These radios are line of sight radios and as such, transmission range are influenced by the degree to which you can see the other communicating party. Large concrete struc-
tures and heavy foliage or transmission from inside a building or vehicle will reduce the talk power range. Optimal range: wide, open areas free of obstructions. Medium range: large buildings or trees blocking your line of Minimum range: mountainous areas or areas of heavy foliage. sight. 5 11 IC-4088A_3_Draft.qxd 03.7.16 21:05 Page 12 (1,1) 6 GROUP MODE (CTCSS) I Setting the group code The IC-4088A is equipped with 38 group codes.

CTCSS (Continuous Tone Coded Squelch System) GROUP MODE allows communication with silent stand by. Only signals containing a specic group code can open the squelch. This conveniently eliminates unwanted audio and is useful in group activities or security related activities where unwanted out-
put can be a problem. Note that CTCSS group mode is not pri-
vateanyone can receive your calls. The IC-4088A is equipped with 38 tone codes for CTCSS GROUP MODE use. Selecting a code applies it to all 14 operating chan-
nels. Each push of [PTT] superimposes your group code over your transmit signal; and, only signals containing the same code can open your squelch. To temporarily hear all signals (including noise) push and hold [MODE].
