Maintenance
Transceiver NF-368 you purchased is an exactitude
design electronic products and please use it carefully.
Following maintenance ways may help extend its
lifetime.
1. Please don’t try to disassemble the transceiver
because non-technicians’ processing may cause
damage to the device.
2. To use stable power supply, please connect the
specified USB cable to the DC jack of the
transceiver.
33
3. Please don’t put the transceiver in sun or hot place
for long time, because the high temperature will
shorten use life of electronic parts and cause
distortion to plastic parts.
4. Please keep the transceiver dry, because rain and
moisture will erode the electronic circuits.
5. Please power off the transceiver and remove its
battery pack immediately once there is peculiar
smell or smog emit from the device.
