DISPLAY BRIGHTNESS The brightness of the LCD display can be selected from OFF, and 1 to 4 by accessing Menu No. 00. 1 Press [MENU/ F.LOCK], then turn the MULTI control to access Menu No. 00. 2 Press [ ]/ [ ] to select "oFF", "1", "2", "3", or "4". 3 Press [MENU/ F.LOCK] to store the setting and exit Menu mode. KEY ILLUMINATION The Remote Control panel key illumination can be switched ON or OFF. 1 Press [MENU/ F.LOCK], then turn the MULTI control to access Menu No. 01. 2 Press [ ]/ [ ] to select "oFF" or "on". 3 Press [MENU/ F.LOCK] to store the setting and exit Menu mode. LINEAR AMPLIFIER CONTROL When you connect an external HF or 50 MHz linear amplifier to the transceiver using the REMOTE connector, select "1", "2", or "3" to activate the internal relay and/ or DC output (12 V) so you can interface with the HF/ 50 MHz linear amplifier {page 80}. The DC output (12 V) works without any annoying chattering sounds ("1") but the output current is limited to 10 mA. If your linear amplifier control circuit draws more than DC 12 V/ 10 mA, use the relay switching ("2" or "3") instead. Also, some linear amplifiers require a long transmission delay time because of the slow antenna relay switching time. In this case, select "3" for the slow switching (25 ms delay). 1 Press [MENU/ F.LOCK], then turn the MULTI control to select Menu No. 28 (HF) or 29 (50 MHz). 2 Press [ ]/ [ ] to select "oFF", "1", "2", or "3".
