SWAPPING THE OPERATING DATA BETWEEN MAIN BAND AND SUB BAND There two independent receivers in this transceiver, such as the main band and the sub band. These two receivers can behave separately; hence, you can configure different frequencies and modes for each band. If there is only one key available for the main band and sub band, you can operate the transceiver with the key by swapping the operating band for the main band and sub band. The frequency displayed on the left side of the main screen is the main band, and the one on the right side is the sub band. . 1 Rotate the AF (M) or AF (S) control. • Clockwise increases the volume and counterclockwise decreases it. Note: ◆◆Depending on the configurations for Squelch and CTCSS, no audio sounds even with a rotation of the AF control. In such a case, rotate the SQL control counterclockwise or deactivate the CTCSS. 1 Press [] to select the band to operate. • Frequency display for the band to operate will be larger in the main screen. • Main Band: The "MAIN" LED lights green. • Sub Band: The "SUB" LED lights green. MUTING THE RECEIVED AUDIO You can mute the received audio with a simple key press, rather than by rotating the AF control. You can press [MUTE] for the main band and the sub band respectively. For example, if you are receiving on both the main band and the sub band, but would like to concentrate on listening to the received audio of the station calling on the main band, you can temporarily mute the sub band. 1 Press [MUTE] (M) or [MUTE] (S) to mute the received audio. • The "MUTE" (M) or "MUTE" (S) LED light orange. • Press again to make the received signal audible. Note: ◆◆The "HIGH/SHIFT LOW/WIDTH" (Sub) LED turns Off upon selection of the main band, and lights orange upon selection of the sub band so as to prevent fault operation. Contents Index 4-7
