This guide walks dental professionals through everyday operation of the XRD 70 portable handheld dental X-ray. In about a minute and a half, it shows how to power the unit on, use the four home-screen controls (Mode, Teeth, Up, and Down), select the patient mode, choose an optimized tooth-region preset, set a custom exposure time, lock and unlock the system, capture the X-ray by pressing and holding the trigger (70 kV, 2 mA, Canon tube), review the cumulative radiation dose, clear an Error E01, and verify the live kV and mA output.

Steps shown in the guide

1. Power on — press and hold the power button for three seconds, until the display turns on.
2. Home-screen controls — four controls run everything: Mode, Teeth, Up, and Down.
3. Patient mode — press Mode to choose Adult or Child; the XRD 70 sets the exposure profile automatically.
