install the remote indicator connector to the receiver

now (refer to Figure 8).

larger wire. You can wire the D306 a maximum of

500 ft (152 m) from the receiver.

2. Slide the remote indicator connector over the pins

located to the right of the receiver’s terminal strip.

Refer to the D307 Installation Instructions (P/N:
