OVERVIEW

The Hotronic FootWarmer is dedicated to your foot wherever it goes and
easily transfers from one type of footwear to another. Based on
computer technology, Battery Pack"s micro-controller permits four (4)
temperature-duration settings. High quality, rechargeable NiMH batteries
are selected for cold temperature performance. Heating Elements locate
directly under toes. Recharger globally accepts input ranging from
100-240VAC, 50/60Hz. Following temperatures and durations are
approximations only as ratings are affected by recharging process and
various tolerances of batteries and electronics. Durations are
determined when Battery Packs are used in ambient temperature of
-4°F (-20°C).

OPERATING BATTERY PACK SETTINGS

1. To turn on or off, press-and-hold ON or OFF until LED light is ON or
OFF (~2.0 seconds).
2. To change setting, press-and-hold
changes (~0.5 seconds).
3. Once selected, setting 4 auto-resets to setting 3 after 3 minutes
("timed setting 4"). ("Timed setting 4" LED lights are ON continuously
and do NOT blink.)
4. To use "continuous setting 4", start at "timed setting 4", then press
and hold until all LED lights blink (~5.0 seconds). ("Continuous
setting 4" LED lights BLINK continuously until setting is changed.)
5. DO NOT USE "TIMED SETTING 4" or "CONTINUOUS SETTING 4"
for more than three minutes at a time as it may become too hot and
may result in burns. SEE CAUTIONS REGARDING BURNS.

BATTERY PACK LED LIGHTS (LEDs)

1. Battery Pack LEDs indicate power is on or off and setting selected.
LEDs do not indicate charge level.
2. LEDs will not light when batteries are fully discharged, are below
minimum voltage cutoff level, or do not have enough power to heat
Element.

EXCESS HEAT ON ANY SETTING, INCLUDING OFF

1. WHEN BATTERY PACK LED stays ON and CANNOT BE TURNED
OFF, water may be around electrical contacts, may cause Heating
Element to become hot at any setting, and MAY RESULT IN BURNS.
See CAUTIONS REGARDING BURNS.

2. WHEN BATTERY PACK IS ON ANY SETTING, INCLUDING OFF,
and you feel your foot getting hot, you think you might be getting a
burn, or you experience any early warning sensations of a burn,
IMMEDIATELY UNPLUG Heating Element from Battery Pack and
IMMEDIATELY REMOVE your foot from FootWarmer. See
Cautions Regarding Burns.

USING HEAT SETTINGS

1. Use FootWarmer to maintain comfort and warmth. (Note: Prevent feet
from getting cold. Warming cold feet requires more energy, is less
effective, and is not intended use of FootWarmer.)
2. Before going into cold, set at 1, 2, or 3 to maintain comfort and
warmth.
3. For additional burst of heat, set to "timed setting 4". "Timed setting 4"
auto-resets to setting 3 after 3 minutes.
4. DO NOT USE "TIMED SETTING 4" or "CONTINUOUS SETTING 4"
for more than three minutes at a time as it may become too hot and
may result in burns. SEE CAUTIONS REGARDING BURNS.
5. Heat does not thermostatically cycle on and off. Settings 1 and 2
maintain warmth AND save energy.

WHAT TO EXPECT OF HEAT SETTINGS

1. Expect imperceptible heat to maintain comfort and warmth.
2. Do not expect "fireplace toes".
3. Learn what personally works best over time.
4. Think of your FootWarmer as Thermo Active Insulation (TM). As cold
penetrates through insole, it draws heat off Element rather than toes.
Balanced heat is imperceptible yet maintains comfort and warmth.
Too much heat and feet feel excess heat. Too little heat and feet feel
cold penetrating through.
5. If feet are comfortable yet feel excess heat, turn to lower setting to
minimize perspiration and maximize battery duration.
6. If feet begin to feel cool, turn setting up to maintain comfort and
warmth.
7. If you think FootWarmer is not working, try turning left Battery Pack
off. If left foot becomes colder, FootWarmer is working.
8. Ability to feel heat and maintain comfort and warmth depends upon:
proper installation; type, fit, and dryness of footwear, sock, and insole;
foot callus size; activity levels; weather conditions; and other factors.
9. Expect bottom of toes to feel heat less than fingers and hands.

COMFORT AND WARMTH RANGES

When first learning use of FootWarmer, following chart may help in
setting selection. Chart represents approximate ranges for comfort and
warmth maintenance. First determine outside temperature then select
setting based on personal sensitivity to cold. More sensitive select left of
range. Less sensitive select right.
