Setting The Communication Channels - JRC JSS-2250 Instruction Manual

4.3.2

Setting the communication channels

Besides the free frequencies described previously, ITU channel mode and user channel modes
can also be set. The ITU channel mode is mode for using channels based on the international
standard and is built-in to the equipment. The user channel mode is the mode for using channels
on pre-registered frequencies. These modes can be used according to the operations.
