Step-By-Step: Pairing Spectra Receivers for Remote in-cab display functionality.

This pairing process applies to HL760 to HL760, HL760 to CR700, and CR700 to CR700 receiver combinations.

1. Turn Both Receivers On

Make sure both units have good batteries.

---

2. Activate Menu

On the receiver you want to configure:

• Press Menu
• Scroll to RDIO
• Press Enter

---

3. Select Radio Mode

• Scroll to RDIO HL
• Press Enter

---

4. Select Pair

• Scroll to PAIR ↑
• Press Enter

Now repeat the same steps on the second receiver.

---

5. Power Cycle

After pairing:

• Power both receivers off
• Power on the receiver you want to be the main laser receiver first

That unit becomes the primary receiver.

The second receiver will display:

“RMT.D OKAY”

Press Enter to confirm remote display mode.

You will now see a radio symbol on both receivers indicating successful communication.

What “MODE HL” Means

MODE HL sets handheld receiver 2-way communication to operate with another CR700 or HL760.

After pairing:

• Turn the receiver off
• First unit powered becomes main receiver
• Second unit confirms as remote display

---

What “PAIR ↑” Means

PAIR stores an identification code in memory so the two receivers communicate only with each other.

This prevents cross-communication from other crews working nearby.

---

Pairing Other Receiver Combinations

This procedure is essentially the same for:

• Pairing two HL760 receivers together
• Pairing two CR700 receivers together
• Pairing an HL760 to a CR700 in either direction

The menu structure and pairing steps remain consistent.
