Use [B] key to writetuning data through tuning modes, and [ ]/[ ] to adjust tun-ing requirements (1 to 256 appeares on LCD).Use [C] key to select the adjustment item through tuningmodes. Use [A] key to adjust 3 or 5 reference level adjust-ments, and use [■] key to switch between Wide 5k/Wide 4k/Narrow.Channel appears on LCD.
