CIRCUITS & ZONES (CONTINUED)
The option in Fig 6.1.3 A could be implemented by "tacking" the 560E resistor (or 6V8
Zener) onto the PCB. The 2 AZC option (Fig 6.1.4) could also be implemented by soldering
the extra resistor and wires onto the unused contact of the rotary switch on the PCB.
In all cases, "auto" is zone "normal".
