COOLING FAN AND TEMPERATURE PROTECTION FOR
FINAL UNIT
To protect internal circuits from high temperatures, the
transceiver senses the temperature of the final unit
regardless of the operation state, either transmitting or
receiving, and controls the cooling fan rotation speed for
the final unit and the transmit power as described below.
If a thermistor detects a temperature increase in the final
unit, the cooling fan at first starts rotating at low speed. If
the temperature increases further, the cooling fan rotates
at high speed.
If excessively high temperature is detected, the transmit
power is limited until the internal temperature cools down.
Note:
◆ If a message notifies you of a detected high temperature, do not
shut down the transceiver with a press down of the main I/O power
switch to the "O" position.
◆ If the main power (I/O) is shut down, the cooling fan stops, and it
may take longer until the transceiver cools down.
