1 PANEL DESCRIPTION e TX/RX LED ➥➥Lights green when the squelch opens, or a signal is received. ➥➥Lights red when transmitting. y PBT LED Lights green when the [M-CH/BANK] controls act as the PBT control. • Push the [M-CH] switch to select PBT control. r MEMORY BANK CONTROL [BANK] ❍ When both the PBT and RIT LEDs are OFF Rotate to select a Memory bank. ❍ When the PBT LED (y) lights green (Mode: SSB/CW/RTTY/AM) Rotate to adjust the receiver's IF filter passband width using the DSP circuit. ❍ When the RIT LED (u) lights orange Disable this control. t M-CH CONTROL•CLEAR SWITCH [M-CH]•[CLR] Push to select the action of the [M-CH/BANK] con- trols as the Memory/Bank selection, PBT control or RIT control. ❍ When the both RIT and PBT LEDs are OFF Rotate to select a Memory channel. ❍ When the RIT LED lights orange ➥ Rotate to adjust the RIT frequency shift. • The frequency shift range is ±9.99 kHz in 10 Hz steps. The control tunes in 1 Hz steps when the operating frequency readout is set to the 1 Hz step. ➥ H old down for 1 second to clear the RIT shift frequency. ✔ What is the RIT function? The RIT (Receiver Incremental Tuning) shifts the receive frequency without shifting the transmit frequency. This is useful for fine tuning stations calling you off-frequency, or when you prefer to listen to slightly differentsounding voice characteristics. ❍ When the PBT LED lights green (Mode: SSB/CW/RTTY/AM) ➥ R otate to adjust the receiver's IF filter pass- band width using the DSP circuit. ➥ H old down for 1 second to reset the PBT set- tings. • The PBT is adjustable in 50 Hz steps in the SSB/ CW/RTTY modes, and 200 Hz in the AM mode. At that time, the shift value changes in 25 Hz steps in the SSB/CW/RTTY modes, and 100 Hz in the AM mode. • The PBT controls function as an IF shift control. ✔ What is the PBT control? The PBT function electronically modifies the IF passband width to reject interference. This transceiver uses the DSP circuit for the PBT function. u RIT LED ➥➥ Lights orange when the RIT function is turned ON. ➥➥Lights orange when the [M-CH/BANK] controls act as the RIT control. • Push the [M-CH] switch to select RIT control. • T he RIT control is the inner control. The outer control is disabled. i RIT KEY RIT (AI sec. 5) ➥➥Push to turn the RIT function ON or OFF. • Use the [M-CH] control to vary the RIT frequency. ➥ Hold down for 1 second to add the shift frequency of the RIT function to, or subtract it from, the displayed frequency. o ANTENNA TUNER/CALL KEY TUNER/CALL ❍ ANTENNA TUNER KEY Operation (AI sec. 16) (Frequency band: HF/50 MHz) ➥ Push to turn an optional automatic antenna tuner ON or OFF (bypass). ➥ Hold down for 1 second to manually tune the antenna tuner. • If the tuner cannot tune the antenna within 20 sec- onds, the tuning circuit is automatically bypassed. ❍ CALL KEY Operation (AI sec. 11) (Frequency band: 144/430 MHz) Push to select the Call channel. In the 70 MHz band, push to sound an error beep. !0 MENU KEY MENU (p. 1-10) Push to change the set of functions assigned to the touch keys. • T oggles the function display menu between M-1, M-2 and M-3 menus or D-1 and D-2 menus. !1 M IC GAIN/RF POWER ADJUSTMENT KEY MIC/RF PWR (p. 3-24) Push to open the MIC gain/RF power adjustment display. • Rotate [M-CH] to adjust the MIC gain. • R otate [BANK] to adjust the RF power. Frequency band RF output power range HF/50 MHz 2 to 100 W (AM: 1 to 30 W) 70 MHz* 2 to 50 W (AM: 1 to 15 W) 144 MHz 2 to 50 W 430 MHz 2 to 35 W • P ush again to close the window. * 70 MHz band transmission is available, depending on the transceiver version. 1-3
