A service technician is required depending on whether the system was initially installed as Pre-Assembled or Assembly on Site. Please contact AlterG Customer Support for additional instructions.
The “E” indicates that the Emergency magnet has been pulled. The VIA and M/F320 will not function until the Emergency magnet has been replaced.
Use the following table to troubleshoot a system error.
| Code | Explanation | Action Taken |
|---|---|---|
| E | The safety magnet has been displaced. | Ensure the cockpit is fully locked in position and press Start. |
| L | The cockpit has not been locked prior to Start. | Ensure the cockpit is fully locked in position and press Start. |
| OPR | Over Pressure Error. The pressure is higher than requested for a particular degree of unweighting. Outflow from the pressure control valve may be blocked or the valve may not be operating correctly. | Outflow from the pressure control valve may be blocked or the valve may not be operating correctly. Press Start. If the error persists, contact AlterG Customer Support |
| UPR | Under Pressure Error. The system is unable to reach requested pressure for a particular degree of unweighting. There may be a leak, the subject may be too heavy, or the output of the blower may be blocked. | Check system for leaks. Press Start. If error persists, please contact AlterG Customer Support |
| SCO | The Scale Offset value is out of range. Only on new installation. See Base Weight setting instructions. | Remove the subject from the system. Check the Base Weight via instructions in manual. |
| PRS | The Pressure Offset value is out of range. The pressure sensor may need replacement. | Remove the subject from the system. Raise the cockpit and cycle the power switch off/on. Wait 30 seconds before attempting to use the system again. If error persists, please contact AlterG Customer Support |

If your Woodway treadmill is creeping, please contact AlterG and a technician will walk you through the calibration process.
Video Monitoring System (VMS)
There are three cameras on the VMS. One front-mounted permanent camera and two side cameras, mounted on stands, which can be freely positioned.
The Video Monitoring System requires that a 120VAC outlet be available within ten feet of the front of the Anti-Gravity Treadmill.
The primary use of the Video Monitoring System is to allow the user to view their workouts on the video monitor. AlterG cannot guarantee availability of all additional inputs as VMS monitors can change when the manufacturer discontinues specific models.
Shorts
AlterG Standard Shorts are available in 3XS-4XL. AlterG Performance Shorts are available in XS-3XL.
Shorts should be inspected regularly for normal wear and tear. Replacements should be ordered if holes, tears, rips, and/or severe unstitching are found.
Your AlterG shorts can be hand-washed, machine-washed, or disinfected/sanitized using AlterG approved sprays. Please review our Shorts Care Guide for additional information.
Shorts may be ordered by contacting the AlterG Customer Support team.
Shipping
Our Treadmills are shipped using a full van line service and are delivered to the exact location within the facility or home. Our freight rates are for a two-man crew in addition to a certified AlterG Technician.
Your AlterG Sales Associate will work with you to schedule an installation date. Once a date has been approved, it takes nine business days for transit. The planning and installation process will take three weeks or more and cannot proceed without a verified site survey with proper electrical service.
Delay in submission of the Site Survey and/or incorrect electrical or entryway specifications can delay deliveries.
