#3MULTI-FUNCTION SWITCHES

Push to select the functions indicated in the LCD display to the right of these switches.

• Functions vary depending on the operating condition.

MF1 (MULTI-FUNCTION 1 SWITCH)

ANT

Selects the antenna connector from

1ANT1, ANT2, ANT3 and ANT4 when pushed. (p. 10-2)

Displays antenna selection memory when pushed and held for 1 sec.

When the receive antenna is activated, the antenna connected to [ANT4] is used for receive only.

When a transverter is in use, this [ANT] does not function and ‘TRV’ appears.

MF2 (MULTI-FUNCTION 2 SWITCH)

METER

 

Selects RF power (Po), SWR, ALC,

 

 

COMP, VD or ID metering during trans-

Po

 

 

 

mit. (p. 3-10)

Switches the multi-function digital meter ON and OFF when pushed and held for 1 sec. (p. 3-10)

MF3 (MULTI-FUNCTION 3 SWITCH)

P.AMP

Selects one of 2 receive RF preamps

1or bypasses them. (p. 5-9)

“P. AMP1” activates 10 dB preamp.

“P. AMP2” activates 16 dB high-gain pre- amp.

What is the preamp?

The preamp amplifies signals in the receiver front end to improve S/N ratio and sensitivity. Select “P. AMP1” or “P. AMP2” when receiving weak signals..

MF4 (MULTI-FUNCTION 4 SWITCH)

ATT

Selects 6 dB, 12 dB or 18 dB attenua-

tor when pushed. (p. 5-9)

OFF

Turns the attenuator function OFF when pushed and held for 1 sec. (p. 5-9)

What is the attenuator?

The attenuator prevents a desired signal from being distorted when very strong signals are near the desired fre- quency, or when very strong electromagnetic fields, such as from a broadcasting station, are near your location.
