  If your Hanger Medical Equipment unit isn't powering on, first ensure the power cord, specifically a HOSPITAL GRADE plug, is correctly plugged into both the unit and a functional AC outlet. Check the cord for any signs of fraying or damage. If the outlet isn't working, try a different one.

  If the 'APPL' message shows up on your Hanger Medical Equipment unit, check that the drum inductive applicator connector is properly plugged into the back of the main unit. Make sure the connectors are securely attached. If the message persists after restarting the unit, further assistance is needed.

Why patient cannot detect output from Hanger ACP MEGAPULSE II?

  kylegarciaAug 27, 2025
  If a patient can't feel the output during a treatment with your Hanger Medical Equipment, check if the drum inductive applicator is emitting output. If available, use an output tester to see if the unit is working correctly. If the LED is not properly illuminated, unit replacement is needed. If the LED is lit, stop the treatment and check the patient for impaired sensation in the treatment area.

This document is the User Manual for the MEGAPULSE® II Shortwave Diathermy system, manufactured by Accelerated Care Plus (ACP), a Hanger Company.

Function Description:

The MEGAPULSE® II is a pulsed shortwave diathermy device designed to therapeutically increase tissue temperature. It operates by generating high-frequency currents (27.12 MHz) that cause vibration of ions and molecules within cells and tissues, leading to tissue heating. The energy is directed to the body without direct electrical contact of electrodes, primarily through an inductive drum applicator. This system is part of ACP's premier line of rehabilitation technologies, aimed at improving patient outcomes and quality of life.

Indications for Use:

Diathermy is generally accepted to produce desirable therapeutic effects such as:

Relieving pain
Increasing the extensibility of collagen tissues
Decreasing joint stiffness
Relieving muscle spasm
Increasing local blood flow

Specifically, the MEGAPULSE® II is indicated for use in:

Disorders of the musculoskeletal system: Muscle spasm, joint stiffness, joint contractures.
Chronic inflammatory or infective conditions: Tenosynovitis, bursitis, synovitis, chronic inflammatory pelvic diseases.

Contraindications:

Patients who do not understand potential risks or cannot cooperate in maintaining position and reporting heating sensations.
Pregnant patients.
Open wounds, hemorrhage, ischemic tissue, tuberculous joints, or acute infections within the treatment area.
Patients lacking normal pain and thermal sensation in the treatment area.
Over or in close proximity to active cancer (except terminal/palliative/hospice care).
Patients with Cardiac Pacemakers, implanted defibrillators, or any implanted systems with RF programming, metallic lead, or other implanted systems (within 10 feet).
Over carotid sinus nerves, testes, heart, or eyes.
When high fever is present, over swollen, severe infection, or inflamed areas/skin eruptions.
Over the lumbar or abdominal region, or uterus during menstruation.
Over exposed spinal cord (e.g., following laminectomy, spinal fusion).
Directly over the cranial region.
Directly over the epiphysis of growing bones in children and adolescents.
On a patient connected to patient monitoring devices, or within 5 feet of active monitoring devices.
When metal is present in tissues in the treatment field (e.g., joint replacements, screws, wires, shrapnel, stents, shunts).
Directly over or in close proximity to Deep Vein Thrombosis (DVT).
Through synthetic blend clothing or if the body is wet.
Over areas with excess adipose tissue.

Important Warnings:

Read the User Manual thoroughly before operation.
Operation near other shortwave or microwave diathermy units may cause instability or burns.
Keep cables spaced apart, away from metal or grounded objects, and never cross them.
Do not lean on or hold cables while the generator is activated.
Use a nonconductive treatment table and mattress without metal parts.
Operator and other patients should stand at least 2 feet from the device during application.
All hearing aids must be removed during treatment.
Do not turn on output until the drum is properly placed over the treatment area.
Use caution when applying thermal shortwave over areas with diminished sensation.

Important Precautions:

Application site and settings should be based on prescribing practitioner guidance.
Connect only to properly grounded wall outlets.
Use only ACP-specified accessories, power cords, and supplies.
Do not immerse the device in water or other liquids during cleaning.
Follow manufacturer's prescribed maintenance schedules.
Only qualified service personnel should perform service and repairs.
Inspect and cleanse skin prior to application; check for irritation/burns post-treatment.
Adjust output or discontinue treatment if patient complains of pain or overheating.
Do not apply directly over/under hot or cold packs.
Do not apply treatment after medicated patches, salves, or creams.
Use caution with recent surgical procedures, fractures, or healing bone/soft tissue.
Exercise caution with patients exhibiting psychological or physical hypersensitivity.
Pregnant operators should remain at least 5 meters away from the applicator when the unit is on.

Maintenance Features:

Cleaning and Disinfection:
- Low Level Disinfection (Daily/Routine): Clean equipment daily with ACP germicidal wipes. Wipe common contact surfaces (control panel, diathermy arm, head) with germicidal disposable wipe and allow to air dry. Clean diathermy head with ACP germicidal wipes after each patient use.
- Intermediate Level Disinfection (Between patients for non-intact skin/incontinence): After each use, clean common contact surfaces with ACP germicidal wipes, then wipe again, leaving surfaces wet for at least 5 minutes to air dry.
- Barriers: Use an all-purpose barrier film for surface protection from cross-contamination, especially with non-intact skin or bodily fluids. Apply barrier film over operatory surfaces, adjustment points of the applicator arm, and use a plastic cover over the drum inductive applicator. Barriers are single-use and discarded after each patient treatment.
General Cleaning: Ensure machine is OFF and unplugged before cleaning. Periodically clean outer case, drum inductive applicator, and cables with ACP approved infection control products. Avoid excess moisture. NEVER IMMERSE THE MEGAPULSE® IN ANY LIQUID OR CLEANING SOLUTION.
