OPERATION
Important Notes
• Power Pack must remain CLOSED when operating outdoors. Internal electronics are only protected against moisture when
the lid is closed.
• DO NOT block pressure vent. This vent (item A) prevents pressure/vacuum buildup when there are changes in temperature
or altitude.
• The power pack is equipped with a resettable circuit breaker (item B) to protect the equipment.
Procedure
1. Press the test button (item C) to display the charge level of the power pack.
2. Read the power pack’s battery level on the charge indicator display (item D).
• If the power pack’s battery is below the desired level, then skip to the CHARGING section and perform the steps listed.
3. Connect provided ‘power supply to DC input’ cable (not shown) between the power pack’s DC output connector (item E)
and the DC input connector on the LRAD.
4. Turn on the POWER switch (item F).
5. Once power is on, PWR indicator light (item G) will illuminate. The power pack is now ready for use.
The LRAD Power Pack
The LRAD Power Pack is a portable power system containing two 12-volt batteries and a charger and is designed to power all
LRAD units that have a source power requirement of 12-28 VDC. The Power Pack allows users to power units without being
tethered to an outlet, resulting in greater deployment flexibility.

CHARGING
Important Notes
• Charging must be performed indoors to prevent the internal batteries and electronics from exposure to the elements while
the lid is open.
• All batteries lose capacity through self-discharge. For best performance, it is recommended that re-charge be applied
every 6 months or sooner while in storage, prior to putting power pack into service. Charge at a temperature between
5 °F (-15 °C) and 122 °F (50 °C).
• DO NOT store power packs in hot places—elevated temperatures can lead to capacity loss, leakage, or rupture. Power Packs
should be stored at a temperature above -4 °F (-20 °C) and below 140 °F (60 °C).
Procedure
1. Connect the AC power cable (item H) to an electrical outlet. Cable must be plugged into a 120/230 VAC ground fault circuit
interrupter (GFCI) outlet.
2. Once connected, the Pack will begin charging, and LEDs on the battery charger (item J) will illuminate.
The battery charger has the following LED indicators (shown above):
• AC Power: Illuminates blue when the power cord is plugged into an electrical outlet and AC power is being received.
• System Check OK: Illuminates green after the battery charger successfully completes a self test without any issues.
The self test analyzes batteries and connections to ensure charging can successfully take place.
• NOTE: The self test happens automatically whenever the charger receives AC power.
• NOTE: The self test can take up to two minutes.
• Charge Mode: Indicates the charging status.
• Charging: Illuminates red when charging. Will also flash red during system check.
• Conditioning: Illuminates amber to indicate batteries are holding at 14.6 VDC and charging while conditioning.
• Auto Maintain: Illuminates green when batteries are fully charged and being automatically maintained while
idle.
• Battery Bank Trouble Status: Illuminates red if there is a wiring problem or fault at one of the batteries connected to the
charger.
• Battery Type: Illuminates red for Flooded/STD AGM, the type of batteries used with the power pack.
3. Once sufficiently charged, unplug and store the AC power cord. The Power Pack is now ready for operation.
