6. SELECT A CHANNEL OR CTCSS/DCS
The transmitter and receiver must be on the same channel using the same CTCSS code in order for you to
communicate with another party.
This feature allows you to utilize a less often-used range of CTCSS codes within a main channel to avoid
congestion on the main channel and filter out unwanted noise and static. There are 38 CTCSS codes for each
main channel.
IMPORTANT: The channels must be programmed, using the PC software provided, before using the
device / transmitter for the first time. Only then will the user be able to choose between the available
channels.
To select channels
Press CH+ or CH- to change channels.
To check transmitter and receiver are using the same channel:
Press PTT button. The other party should hear a distortion noise.
NOTE The noise can be loud. Please place earphone a certain distance away from ear when checking to
avoid discomfort.
NOTE By pressing CH+ or CH- button once, a voice prompt will indicate which channel is currently being
used, e.g., “one, two,…”.
By pressing CH+ or CH- button again, you will Increase or Decrease the channel. Voice prompts will
indicate the new channel set.
NOTE To communicate with other units that do not have CTCSS code capability, switch your unit to the same
channel and set the CTCSS code to“0”.
