Page 10: Precautions
PRECAUTIONS To avoid malfunctions and damages, and to achieve full performance, please pay careful attention to the following matters: During transmission, the heat sink may reach a high temperature (approx. 50°C-80°C). Set the amplifier in a well- ventilated place. Do not place objects on top of the amplifier. - Page 11 When utilizing a mono band antenna, check before operation that the antenna is identical with the transceiver operating frequency. When inserting the coaxial switch to either or both of the input and output sides of the amplifier unit in order to operate two sets of transceivers and antennas which have different frequencies, carefully check the position of the coaxial switch.
