- Communication can only be accomplished when the channel and
CTCSS tone frequency of at least two parties are the same.
- The CTC icon will be displayed on the LCD panel if the CTCSS tone
frequency function is enabled.
Channel Selection
In order to communicate with other FRS units, both transmitting and re-
ceiving party must be on the same frequency.
The FRS-3000PK has 14 FRS channels (frequencies) (1-14) indicated by
the large digits on the LCD display panel. Channels 1-7 are shared
GMRS/FRS channels; channels 8-14 are FRS only. Communication with
Audiovox FRS and compatible units is possible on these 14 channels.
Before transmitting on the selected channel, press the Monitor (M) Button
(2, *10) to check the activity on that channel. If there is activity on the
selected channel, change to another channel that is clear.
To change the channel:
- From FRS standby mode, press the MODE button (15, *4) until the
channel number flashes.
- Press the Up Button (10, *12) briefly to move to the next higher main
channel number.
- Press the Down Button (13, *12) briefly to move to the next lower main
channel number.
CTCSS Mode (Sub-Channel) Selection
The Coded Tone Controlled Squelch System (CTCSS) provides 38 Sub-Fre-
quencies. This feature allows you to utilize the coded squelch tones (01–
38) within a main channel and enables you to communicate with another
party on the same main channel using the same subcode. (This filters out
unwanted transmissions without the same coded squelch tone). There
