4 OPERATING BASICS 1 SELECTING A MODE Depending on which operating mode you want to select, press the [LSB/USB], [CW/FSK], or [FM/AM] button. The second function on each button is accessed by 2 again pressing the same button. For example, repeatedly pressing [LSB/USB] toggles between LSB and USB modes. 3 LSB USB CW FSK 4 FM AM SELECTING A FREQUENCY There are two simple methods to select a frequency. A Manual Tuning Turn the Tuning control or press Mic [UP]/[DWN] to select the exact frequency. QUICK MEMO 5 6 7 8 9 10 In SSB mode, the transceiver automatically selects LSB for frequencies lower than 9.5 MHz, and selects USB for 9.5 MHz or higher frequencies if the Tuning control, the MULTI/CH control, or Mic [UP]/[DWN] is used to cross the frequency of 9.5 MHz. This is also true if using the front panel [UP] or [DOWN] button when the 1 MHz Step mode is used. ADJUSTING SQUELCH The purpose of squelch is to silence audio output from the speaker when no signal is present. When squelch is set correctly, you will hear sound only while a station is actually being received. The point at which ambient noise on a frequency just disappears, called the squelch threshold, depends on the frequency. Turn the SQL control clockwise to just eliminate the background noise when no signal is present. Many operators prefer leaving the squelch control fully counterclockwise unless operating full-carrier modes such as FM or AM. 11 IF SHIFT SQL 4 6 2 8 QUICK MEMO 12 0 10 13 14 15 B Direct Frequency Entry (Keypad) Press [ENT], then directly enter the desired frequency using the numeric keypad.

The appropriate meters automatically become functional according to which state the transceiver is in. Peak readings for the S-meter, ALC, SWR, COMP, and PWR functions are held for a brief moment.

When the COMP meter appears, the SWR meter disappears. ◆ Peak Hold readings cannot be deactivated on this transceiver. 16 14
