Why is my cordless scanner no longer communicating with its base?
Explore preventive maintenance
Preventive battery replacement, Wi-Fi coverage audit and a general check of your scanners and mobile computers.
In brief. A cordless scanner only transmits its scans if it is paired with its base, or with a Bluetooth device, and within range of it. Manufacturers cite a scanner that is not paired or is paired with another base, a base that is not powered or not properly connected to the host computer, and a scanner that is too far away. Depending on the model, you pair it again by placing the scanner on its base or by scanning the base's pairing barcode.

Why is the link with the base lost? The causes cited by manufacturers
These causes are taken from the manufacturers' guides; each example names the model concerned. The entry for your model, in the model-by-model table below, gives the exact procedure.
- Scanner not pairedFor the DS3600, Zebra has you scan the base's pairing barcode; on the Datalogic PowerScan 9100, you place the scanner on the base and three rising beeps confirm the link.
- Scanner linked to another baseDatalogic first has you unlink the scanner: “Unlink” label on the PowerScan 9100, base button held for more than 5 seconds then the “Déconnecter” (disconnect) barcode on the PowerScan 9500. On the latter, pressing the button unlinks all the scanners from the base.
- Base not powered or not properly connected to the host computerHoneywell requires a base connected to the mains and to the computer for cordless Granit scanners; Zebra has you check the cable between the base and the host computer.
- Scanner out of rangeOn the Unitech MS852B, a solid green light when not charging indicates a handheld scanner that is paired but disconnected from the host; for Bluetooth on Zebra mobile computers, the manufacturer cites a device more than 10 metres away.
What to check, in order
- Check the basePowered, connected to the host computer, power light on.
- Move the scanner closerThen do a test scan.
- Pair againBy placing the scanner on the base or by scanning its pairing barcode, according to your model's guide; unlink it first if it was linked to another base.
- Check the confirmation signalA single beep on Honeywell Granit scanners, three rising beeps on the Datalogic PowerScan 9100.

Frequently asked questions
How do I re-pair a handheld scanner with its base?
Depending on the model: place the handheld scanner on its base (cordless Honeywell Granit, Datalogic PowerScan) or scan the base's pairing barcode (Zebra DS3600). If it was linked to another base, unlink it first as your model's guide explains.
Why does my handheld scanner beep three times when I scan?
On cordless Honeywell Granit scanners (1981i, 1991i, 2105i), three beeps when scanning mean that the handheld scanner is not linked to its base. Connect the base to the mains and to the computer, then place the handheld scanner on it.
Why does my handheld scanner lose the link with its base?
It is too far from the base, or the base has lost its power or its link with the host computer. Move it closer and check the base; if the link does not come back, pair it again according to your model's guide.
