Configuration codes

To change scanner settings, scan the barcode below directly with the HD7700.

💡 Tip: print this page ("Download this page as PDF" button above) to keep the codes at hand during configuration.

Restore factory defaults

If the scanner does not behave as expected, scan the code below to restore all settings to their default values:

Version information (output the firmware version):

Battery level (output the current battery charge):

Scanning mode

The scanner supports three trigger modes (v6000 QR family):

Manual mode — push button (default):

Continuous mode (one scan after another):

Automatic mode (proximity-triggered):

Connection and pairing

The HD7700 connects to the host in several ways. By default the bundled 2.4 GHz USB receiver works as a keyboard (HID) — just plug it in.

2.4 GHz

2.4 GHz mode (pair with the USB receiver):

Enter pairing mode:

2.4 GHz Virtual COM port

Use this when your software expects a serial (COM) device: scan COM port mode, then Enter pairing mode, plug in the receiver — a COM port is created on the host.

Clock calibration

The time encoded in the code below comes from the supplier manual (an example). To set the current date and time, generate your own code with the supplier's "Scanner Time Setting Offline Web Version" tool (downloadable from symcode.cn) and scan it:

Symbology settings (v6000 QR codes)

The QR codes below enable/disable individual code types and their options (check digit, supplementals, length limits). They come from the supplier's supplementary manual "BARCODE FAMILY ENABLE/DISABLE (v6000)". For length parameters, scan "Set Length Limit" first, then the value code.

Frequently asked questions

What is the difference between the HD7700 and the HD770?

The HD7700 uses a CMOS sensor that reads both 1D barcodes and 2D codes (QR, Data Matrix) including from screens. The HD770 uses a laser engine and reads only 1D barcodes. Both feature a phone holder, Bluetooth, 2.4G and 50,000-code memory.

Can the HD7700 scan QR codes from a phone screen?

Yes. The CMOS imaging engine reads 1D and 2D codes from paper labels and LCD/LED/OLED screens, including smartphone displays.

How many codes can be stored in memory mode?

The built-in memory stores up to 50,000 scanned codes. Stored data can be uploaded to a computer later via USB or wireless connection.

How do I mount a phone in the holder?

The slide-and-clamp mechanism fits phones 14 to 17.5 cm tall and up to 1 cm thick. The cradle has an anti-slip insert, and data can be transferred over Bluetooth or with the included USB-C cable.

How do I configure the HD7700?

All settings are changed by scanning the configuration codes on this page — e.g. keyboard layout, end mark, prefixes/suffixes, operating modes or symbology switches. If anything goes wrong, scan the Restore factory defaults code.
