Low Battery Indicator
The 3M™ PPS™ Sun Gun™ Color Matching Light is configured with a voltage regulator
to insure that the proper spectral output of the lamp is maintained. Once the supplied
voltage drops to a predetermined level, the Low Battery indicator will illuminate to let the
user know that the 3M™ PPS™ SUN GUN™ Battery Pack needs to be recharged. The
3M™ PPS™ SUN GUN™ Battery Pack should be recharged at this time. The lamp will
continue to provide proper spectral output until the voltage regulator determines that the
supplied power is inadequate. At this time the unit will shut-down and the Low Battery
LED will remain illuminated. NOTE: When this occurs, the 3M™ PPS™ SUN GUN™
Battery Pack should be disconnedcted from the 3M™ PPS™ SUN GUN™ Light and
inserted into the 3M™ PPS™ SUN GUN™ Battery Charger. If the battery is allowed to
discharge further, the LED indicator will not illuminate and the switch will not turn on the
light. The 3M™ PPS™ SUN GUN™ Light will not function until the 3M™ PPS™ SUN
GUN™ Battery Pack has been fully recharged. This functionality has been implemented
to insure that the 3M™ PPS™ SUN GUN™ Color Matching Light always provides the
proper spectral output for its intended use.
Cleaning
Only use a mild soap solution on a damp cloth to clean the 3M™ PPS™ SUN GUN™
Light, Battery Pack, Battery Charger or Power Supply. Other cleaners may contain
chemicals that could cause damage to the plastic. Do not use flammable or combustible
solvents (refer to warning and caution instructions). Never let liquids get inside 3M™
PPS™ SUN GUN™ Light; never immerse any part of 3M™ PPS™ SUN GUN™ Light
into liquid.
Replacing the Light Bulb
To replace bulb, remove the lamp bezel by turning it counter-clockwise to release it from the

to release the bulb from its socket. To install a new bulb, insert the bulb into the keyed socket
