How Manaras Rolling Code Remotes Work

Manaras-Opera Series «100» remotes — the RADIOEM 101 (single button) and RADIOEM 144 (three button, up to 144 doors) — use rolling code technology. Every time you press the button, the transmitter sends a new code. The receiver on the operator accepts it once, then marks that code used. A captured code cannot be replayed. This is why you cannot clone a rolling code remote with a generic duplicator. You must pair each remote to the operator’s on-board receiver.

Both models retrofit with older Series «100» Manaras rolling code devices. If your building already has Manaras remotes in use, new ones join the same system without replacing existing transmitters or receivers.

Pairing a RADIOEM 101 to a Manaras Operator

1. Stand within 100 feet of the operator. The LED on the remote will flash during programming.

2. Press and hold the Learn button on the operator’s radio receiver (usually a small push button on the circuit board or a wired learn switch) until the receiver LED lights steady — about three seconds.

3. Within 30 seconds, press and hold the button on the RADIOEM 101. The operator LED will flash rapidly, then go solid. Release the remote button.

4. Press the remote button once more to test. The door should activate.

If the operator LED does not respond, the receiver may be in a different mode or the learn button was not held long enough. Start over from step 2.

Pairing a RADIOEM 144 to a Manaras Operator

The 144 uses two rotary dials to select a door address (1–144) before pairing. Each door in the facility gets a unique address.

1. Set the two rotary dials on the 144 to the address assigned to the door you are pairing. Example: Door 7 = dial 1 at “0”, dial 2 at “7”. Door 112 = dial 1 at “11”, dial 2 at “2”.

2. Press and hold the Learn button on that door’s operator receiver until its LED lights steady.

3. Within 30 seconds, press and hold the Open button on the 144. The operator LED flashes rapidly, then goes solid. Release.

4. Test: press Open — the door should move. Press Close — it should reverse or close. Press Stop — it should halt mid-travel.

5. Repeat for each door, changing the dials to the next address before each new pairing.

The 144 stores all 144 addresses in one handset. You do not re-pair the whole remote when adding a door — only the new address.

Clearing All Remotes from an Operator

When a remote is lost or an employee leaves, clear the receiver and re-pair only the remotes that should remain active.

1. Press and hold the Learn button on the operator receiver until the LED flashes rapidly (usually 10–15 seconds), then release.

2. The receiver memory is now empty. No previously paired remote will work.

3. Re-pair each authorized remote using the steps above.

This is the only way to revoke a lost remote. There is no “delete one remote” function on the operator side.

Using the RADIORE901 Universal Receiver

If the operator is not a Manaras model — or if the on-board receiver has failed — the RADIORE901 universal receiver bridges Manaras rolling code remotes to most commercial operator brands. Wire the RE901’s relay outputs to the operator’s open/close/stop inputs. Pair remotes to the RE901 using its own learn button (same press-and-hold sequence). The remotes then behave exactly as they would on a native Manaras operator.

Common Failure Modes

Remote works intermittently — Usually a weak battery (CR2032 coin cell). Replace it before re-pairing. Cold weather drops coin-cell voltage enough to cut range in half.

LED flashes but door does not move — The remote paired, but the operator did not receive the command. Check antenna wire on the receiver: it should hang loose, not coiled or cut. Metal buildings and reinforced concrete walls absorb signal. Relocating the receiver antenna or adding an external antenna kit often fixes this.

Multiple doors activate from one button — Two operators learned the same remote address. Clear both receivers and re-pair with distinct addresses (critical on the 144).

New remote will not pair at all — Verify the remote is Series «100» rolling code. Older fixed-code Manaras remotes (pre-Series 100) are not compatible. The label on the back of the remote should read “Rolling Code” and show the FCC/IC IDs listed in the spec sheet.

When to Call a Technician

The operator has no learn button visible, or the receiver board shows corrosion / water damage.
You need to integrate remotes with a building access control system (fob readers, keypads, loop detectors).
The facility has more than 144 doors — you need a networked access layer, not handheld remotes.
Pairing works at the bench but fails at the mounted operator — indicates RF environment issues that require spectrum analysis or antenna relocation.

CCGDS stocks RADIOEM 101, RADIOEM 144, and RADIORE901 units. We program on site and verify range at each door.

Next Step

If you have the remote in hand and the operator is accessible, the steps above cover 90 percent of pairings. For multi-door buildings, lost-remote purges, or integration with access control, call (604) 206-5727. We dispatch a tech with the right remotes and receiver hardware the same day.
