TRANSMISSION/ RECEPTION
4.1
Transmit/ Receive Frequencies
Transmit/ Receive Frequencies is a pair of frequencies used for transmitting and receiving.
Transmit and receive frequencies can be configured for each channel.
NX-240/ NX-240V
NX-740H/ NX-740HV
NX-340
NX-340U
NX-840H/ NX-840HU

Transmission Power
Transmit Power is the transmission power of the transceiver.
Portable
For Portable, a user can use the transceiver by switching the transmission power to high power or low power.
If the transceiver is located near repeaters or target party, a user can set the transmission power to be lower in order to
avoid causing unnecessary radio interference to other transceivers. Also, the battery operating time of the transceiver is
extended by reducing power consumption.
NX-240/ NX-240V
NX-340/ NX-340U
Either "High" or "Low" can be configured for Transmit Power for each channel.
If "High" is configured for Transmit Power of the selected channel, the transmit power can be changed to low power by a
press of the Low Transmit Power key. The low power state is retained even after the transceiver is turned OFF. The
transmit power of a channel for which high power is preconfigured can be changed to low power according to the usage
environment.
