Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.
Symbol indicates a capacitor.
No differentiation is made between chip capacitors and
discrete capacitors.
The > mark found on some component parts indicates
the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of
identical designation.

Note:
• To select channels with the AVR-W6100’s main unit, first switch the selection mode to MANUAL/SEEK. Each time you simultaneously press the 2/3 CH button, the mode switches between MANUAL/SEEK and PRESET. Next, switch channels with a CH button.
BSSM (Best Station Sequential Memory)
The BSSM function automatically memorizes strongly transmitted broadcast stations in order from the lowest channel up.
• To switch the BSSM ON, press the CH CALL button for 2 seconds.
Each press changes the Mode ...
• To cancel the process, press the CH CALL button for 2 seconds again before memorization is complete.
