Instructions for use/user manual
Attention: Be sure to read and understand
these Instructions for Use before applying the
firefly™ T-1 device.
1.0 firefly™ T-1 device
1.1
Description of firefly™ T-1 device
The firefly™ T-1 device is a small disposable,
internally powered, neuromuscular stimulation
device for muscle conditioning. It is an integrated
device and there are no additional cables or
electrodes required for its operation. Familiarize
yourself with the components before you use the
device and the skin preparation materials.
1.2 Indications for use
The firefly™ T-1 device is intended for the
stimulation of healthy muscles in order to
improve or facilitate muscle performance. The
firefly™ T-1 device is not intended to be used in
conjunction with therapy or treatment of
diseases or medical conditions of any kind.
2.0 Contradictions
Do not use this device if you have a cardiac
pacemaker, implanted defibrillator, or other
implanted metallic or electronic device. Such use
could cause electric shock, burns, electrical
interference, or death.
3.0 Warnings
• If you are in the care of a physician, consult with
your physician before using this device.
• Do not apply stimulation over your neck because
this could cause severe muscle spasms resulting
in closure of your airway, difficulty in breathing, or
adverse effects on heart rhythm or blood
pressure.
• Do not apply stimulation across your chest
because the introduction of electrical current into
the chest may cause rhythm disturbances to your
heart, which could be lethal.
• Do not apply stimulation over painful areas. If
you have painful areas, you should consult with
your physician before using this device.
• Do not apply stimulation over open wounds or
rashes, or over swollen, red, infected, or inflamed
areas or skin eruptions (e.g., phlebitis,
thrombophlebitis, varicose veins).
• Do not apply stimulation over, or in proximity to,
cancerous lesions.
• Do not apply stimulation in the presence of
electronic monitoring equipment (e.g., cardiac
monitors, ECG alarms), which may not operate
properly when the electrical stimulation device is
in use.
• The firefly™ T-1 device must be kept dry. Do not
use the firefly™ T-1 device in a humid atmosphere
(e.g., sauna, hydrotherapy) or while in the bath or
shower.
• Do not apply stimulation while driving, operating
machinery, or during any activity in which
electrical stimulation can put you at risk of injury.
• Do not use the device on children, it has not been
evaluated for pediatric use.
• Apply stimulation only to normal, intact, clean,
healthy skin.
4.0 Precautions
• The long-term effects of electrical stimulation are
unknown.
• Since the effects of stimulation of the brain are
unknown, stimulation should not be applied
across your head, and electrodes should not be
placed on your head.
• The safety of electrical stimulation during
pregnancy has not been established.
• You may experience skin irritation or
hypersensitivity due to the electrical stimulation
or electrical conductive medium (gel).
• Consult your physician before using the firefly™
T-1 device if any of the following apply to you:
– You are pregnant
– You have a suspected or diagnosed heart
disease
– You have suspected or diagnosed epilepsy
– You have a tendency to haemorrhage (bleed
internally) after an injury or fracture
– You have had a recent surgical procedure as
muscle contractions may disrupt the healing
process
• Follow any other precautions recommended by
your physician.
• Use caution if stimulation is applied over areas of
skin that lack normal sensation.
• Keep this device out of the reach of children.
• Use this device only with the leads, electrodes,
and accessories recommended by the
manufacturer.
• Operation in close proximity (e.g. within 3 feet) to
a shortwave or microwave equipment may
produce instability in the stimulator output.
• The firefly™ T-1 device has no replaceable or
serviceable parts and requires no user
maintenance. The unit must not be disassembled.
• The firefly™ T-1 device is not compatible for use
with an MRI scanner. Remove the device if you
need to undergo an MRI.
• Do not share the firefly™ T-1 device with others.
Everyone should have their own device to avoid
any possibility of contamination that could result
in skin reactions.
• Do not use the firefly™ T-1 device if the device or
its packaging show visible signs of damage.
5.0 Adverse reactions
Some users may experience skin irritation or
hypersensitivity due to the adhesion material,
electrical stimulation or electrical conductive
medium. If this happens, you can try reducing the
irritation by using an alternate electrode
placement, see fireflyrecovery.com for further
details. If the skin irritation is significant, switch off
the device, remove, and discontinue use. If the
skin irritation persists you should consult with
your doctor.
6.0 Reporting of any side effects or
adverse reactions
Any side effects or adverse reactions due to use
of the firefly™ T-1 device should be reported
