8. Using a Transceiver
(1) When a transceiver is used very near a transmitter, its transmission frequency (in
the form of high frequency noise) may cause radio interference.
(2) When using a transceiver, determine the distance that will be necessary for avoid-
ing any interference, and ensure that the distance between the transceiver and the
transmitter is greater.
(3) When using a transceiver, be sure to close the cover of the transmitter
9. Welding in Proximity
(1) When welding is to be carried out near the transmitter, the welding current may
affect the operation of the transmitter depending on the grounding method.
(2) Directly ground the welding equipment and power transformer. Do not ground to
the stanchion pipe of the transmitter.
(3) Turn off the power supply to the transmitter.
