■ About protection indications 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. • Power down 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 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. ■ Screen saver function The IC-7600 has a screen saver function to protect the LCD from the "burn-in" effect. q P ush [EXIT/SET] several times to close a multifunction screen, if necessary. w Push [SET] (F-6) to select set mode menu screen. e Push [DISP] (F-3) to enter display set mode. r P ush [Y] (F-1) or [Z] (F-2) several times to select the "Screen Saver Function" item. t R otate the main dial to select the desired time period for the screen saver activation from 15, 30, 60 min. and OFF. • Deactivate the screen saver with "OFF" selection. y P ush [Z] (F-2) to select the "Screen Saver Type" item. u R otate the main dial to select the screen saver type from "Bound," "Rotation" and "Twist." • Push and hold [PREVIEW] (F-5) to display the indica- tion for your reference. i P ush [EXIT/SET] twice to exit set mode.

About protection indications
The IC-7600 has a 2-step protect±on funct±on to pro-
tect the f±nal power ampl±f±ers.
The protector mon±tors the power ampl±f±er temper-
ature and act±vates when the temperature becomes
extremely h±gh.
• Power down transmission
Reduces the transm±t output power to 50 W.
“LMT” appears bes±de the TX ±nd±cator (p. 14) dur-
±ng transm±t.
• Transmission inhibit
Deact±vates the transm±tter.
The TX ±nd±cator (p. 14) ±s d±splayed ±n gray dur±ng
transm±t.
When the protector ±s act±vated, wa±t unt±l the
power ampl±f±er cools down us±ng the transce±ver ±n
stand-by or rece±ve cond±t±on.
NOTE: DO NOT
turn the transce±ver power OFF
when the protector ±s ON. If you do, the cool±ng fan
w±ll not funct±on and ±t w±ll take longer to cool the
transce±ver.
The power ampl±f±er temperature can be mon±tored ±n
the mult±-funct±on meter, TEMP gauge.
