3.4 Setting and Operation
3.4.1 BASIC CHANNEL SELECTION
In order to communicate with other PMR units, both you and the receiving party
must be on the same channel. Tectalk has 8 channels (1-8) as indicated by
the large digits in the LCD Display Panel (#8).
Before, trying to transmit on the selected channel, you should press the Monitor
Button (#2) to check the activity on that channel.
If someone is already on the selected channel, you should try another
channel which is not occupied.
To change the basic channel, in the standby mode, press the
Up Button (#10)
briefly to move to the next higher main channel number.
Press the
Down Button (#11)
briefly to move to the next lower main channel
number.
3.4.2 CTCSS (Coded Tone Controlled Squelch System)
SUB-CHANNEL SELECTION MODE
This feature allows you to have more privacy on the main channel by using tone codes
(international numbering system 00-38) within a main channel. This enables you to
communicate with Your partners on the same main channel when all partner stations use
the same subcode. This helps to avoid congestion on the main channel and filters out
unwanted noise, static and other stations using different codes.
There are 38 CTCSS subchannels for each main channel.
To change the CTCSS subchannel,
Press the Function Button (#12) until the word cTc appears in the LCD Panel (#8).
Press the Up Button (#10) or the Down Button (#11) to choose the desired subchannel to
use. The corresponding subcode frequency will be displayed in the lower right corner.
Press the Enter Button (#13) to confirm your selection.
NOTE:
To communicate with other PMR units, they must be switched to the same
channel and CTCSS subcode. To communicate with other LPD units that do
not have subcodes, switch your unit to the same channel with the subcode
set to OFF.
3.4.3 AUTO CHANNEL SCAN MODE
This feature allows you to scan for an active channel and communicate with the party
transmitting.
