About protection indications
The IC-7700 has a 2-step protection function to pro-
tect the final power amplifiers.
The protector monitors the power amplifier tempera-
ture and activates when the temperature becomes
extremely high.
• Power down transmission
Reduces the transmit output power to 100 W.
“LMT” appears beside the transmit indicator during
transmit.
• Transmission inhibit
Deactivates the transmitter.
The transmit indicator is displayed in gray during
transmit.
When the protector is activated, wait until the
power amplifier cools down using the transceiver in
stand-by or receive condition.
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.
