A NOTE FROM THE HEAD MONSTER
THANK YOU for purchasing the Monster Power®Home Theater Uninterruptible Power Supply 3700. The
HTUPS 3700 is designed to maintain power to critical home theater components during power outages for
up to 4 hours* with an internal backup battery. This lets your DVR record scheduled shows, preserves home
theater settings, prevents data corruption on media servers, and prevents costly projector bulb damage.
The HTUPS 3700 also incorporates Monster’s patented HD Clean Power filters, which are specifically engineered
for today’s digital high definition components. This advanced technology reduces stress on delicate digital
circuitry, delivering improved performance and maximizing the lifespan of connected equipment.
Monster’s advanced surge protection technology features patented Tri-Mode that automatically disconnects equipment from
both live power lines (line and neutral) and sounds an alarm. Microprocessor-controlled T2 works with Tri-Mode circuitry to
automatically disconnect both the PowerCenter itself and your equipment from damaging surges and spikes.
The HTUPS 3700 also features automatic voltage regulation, which keeps the voltage going to your home theater within
a safe range.
To save you energy and money, the HTUPS 3700 includes Monster GreenPower™switched outlets that automatically shut
off when you’re not using the equipment connected to them. This stops energy waste caused by HDTVs, Blu-ray Disc™
players and other components in stand-by mode.
I’m sure you’ll enjoy the advanced protection, enhanced home theater performance, energy savings and backup power
reassurance the HTUPS 3700 provides.

PATENTED MONSTER HD CLEAN POWER®FILTERING
Your home’s electricity is full of noise and interference caused by all of your appliances and electronics: cell phones,
computers, even your lights, all contribute to the problem. This “dirty power” stresses the delicate digital circuitry inside
HDTVs and other home theater equipment, reducing their performance and potentially shortening their lives.
However, ordinary surge protectors can’t remove the effects of dirty power. The HTUPS 3700 features HD Clean Power
Stage 3 filtering that is precision-engineered to remove electrical noise and interference. This protects the delicate circuitry
inside your HDTV and other electronics from unnecessary wear. HD Clean Power maximizes your equipment’s lifespan and
ensures the best possible picture and sound performance.

PATENTED MONSTER T2™TECHNOLOGY
The Monster Power HTUPS 3700 features exclusive Monster T2 technology. T2 is an active electronic microprocessor-
controlled circuit that sits in front of the surge protection circuitry in select Monster Power products. T2 monitors the line,
neutral and ground lines and automatically disconnects the HTUPS 3700 from the AC power line when a long duration
low-voltage sag or high-voltage swell occurs (continuous voltage below 80Vrms or above 132Vrms).
Unlike ordinary power management devices, T2 will disconnect the HTUPS 3700 before the MOVs (Metal OxideVaristors)
and thermal fuses sense an overload condition and sacrifice themselves to protect your connected components. This will
extend the PowerCenter’s life, while providing the system protection you need.
™

MONSTER AUTOMATIC VOLTAGE REGULATION
Your home theater electronics are engineered to operate at 120 volts. But common power sags and swells can severely
affect the performance and life of your valuable audio and video equipment. When this occurs, Monster automatic voltage
regulation keeps the voltage going to your home theater within a safe range. This reduces wear on delicate circuitry,
extending the life of your home theater components.
MONSTER GREENPOWER™OUTLET MANAGEMENT
Monster GreenPower is a revolutionary new way to automatically eliminate energy waste and save money. Simply
plug your HDTV or AV receiver into the Monster GreenPower Control outlet. When it’s turned off or goes to sleep,
the Monster GreenPower outlets switch off, automatically eliminating energy wasted by your subwoofer, DVD player,
and more, when you’re not using them. When your HDTV or AV receiver switches back on, the GreenPower outlets
automatically power up again.

MONSTER COUNTDOWN TECHNOLOGY
The Monster HTUPS 3700 features a digital LED display that displays remaining battery power time in minutes. You can instantly
see how much time you have left to safely shut down your system, or how much time you can keep your system running.
When power to the HTUPS is cut, the LED screen automatically switches from displaying voltage to the Countdown timer,
which will begin counting backwards to zero. The Countdown start time will vary depending on how much battery capacity
you have, the initial battery charge level, and the power consumption of equipment connected to the UPS.
The Countdown timer actively measures current draw. As you turn on or off individual components in your system, the
Countdown timer will dynamically adjust to reflect the backup time left. The more power consumed, the less time available,
the less power being used, the more time available.
Backup Time Testing
You can test various system configurations to see how much backup time you’ll have when there’s a power outage. First,
fully charge the HTUPS 3700,* and plug all your equipment into the HTUPS 3700. Refer to the setup instructions on pages
9-10. Then unplug the HTUPS 3700 from the wall outlet so it’s running purely on battery power. The HTUPS 3700
Countdown timer will activate displaying backup time.
You may want to try testing with different components into the UPS outlets to gain more backup time.
*Charge the battery for at least 4 hours to reach full charge capacity.
