About Protection Displays; Screen Saver Function - Icom IC-7600 Instruction Manual

■ About protection displays

The IC-7600 has a 2-step protection function to
protect the final power amplifiers.
The protector monitors the power amplifier
temperature and activates when the temperature
becomes extremely high.
• Reduced power transmission
Reduces the transmit output power to 50 W.
"LMT" appears beside the TX indicator (p. 14)
during transmit.
• Transmission inhibit
Deactivates the transmitter.
The TX indicator (p. 14) is displayed in gray during
transmit.
When the protector is activated, wait until the
power amplifier cools down, using the transceiver
in only stand-by or receive mode.
NOTE: DO NOT turn the transceiver power OFF
when the protector is ON. If you do, the cooling fan
will not function and it will take longer to cool the
transceiver.
The power amplifier temperature can be monitored in
the multi-function meter, TEMP gauge.
