This manual explains how to install batteries, connect the output leads and attach the conductive electrode band, then operate the FM‑56 BGS therapy unit. It describes the eight treatment modes, adjustable output intensity, automatic polarity switching and timer functions.
Safety precautions, contraindications and detailed troubleshooting steps are included, along with maintenance instructions for the electrode pads and storage guidelines. This manual is written in Chinese.
| Battery type | 4 × AA (DC 3.0 V) |
|---|---|
| Frequency range | 2 – 150 Hz |
| Maximum working current | 30 mA |
| Output wave‑adjustment steps | 0 – 8 (8 steps) |
| Output function modes | A‑H (8 modes) |
| Battery life | ≈ 30 hours (continuous use) |
| Weight (without battery) | ≈ 60 g |
| Weight (with battery) | ≈ 76 g |
Check that the batteries are correctly installed and have sufficient charge; replace them if needed, then verify that the power switch and connector are properly engaged.
Press the mode‑selection key to cycle through the eight modes (A‑H). The device will automatically reduce output intensity to zero when a new mode is chosen, allowing you to set the desired intensity afterward.
