INTRODUCTION CHAPTER 1

To prevent damage to your Q-See product or injury to yourself or to others, read and understand the following safety precautions in their entirety before installing or using this equipment. Keep these safety instructions where all those who use the product will read them.

WARNING! ELECTRIC SHOCK RISK!

nCheck the unit and any accessories included in the package immediately after opening. If items are missing or damaged, repackage and return to the point of purchase.

nUse the proper power source. Only use the power adapter supplied with your system. Do not use this product with a power source that applies more than the specified voltage (100- 240V AC).

nNever insert anything metallic into the DVR. Inserting anything into the DVR or its case can be a source of dangerous electric shock.

nDo not operate in dusty areas.

nDo not expose this product to rain or use near water. If this product accidentally gets wet, unplug it and contact an authorized dealer immediately.

nKeep product surfaces clean and dry. To clean the outside case of the DVR, gently wipe using a lightly dampened cloth (only use water, do not use solvents).

nDo not operate this DVR without the cover securely in place. Do not attempt to do any repairs to the DVR yourself. If there are unusual sounds or smells coming from the DVR, unplug it immediately and contact Q-See technical support. Under no circumstances should the cover be removed while the device is connected to a power source. You should only remove the cover to install/replace the hard disk drive (See Chapter 7) or replace the standard 3v lithium cell battery on the motherboard. These are the only user serviceable parts. You may need to replace the battery if the internal clock resets itself after a power outage

nHandle DVR box carefully. If you accidentally drop your DVR on any hard surface, it may cause a malfunction. If the DVR doesn’t work properly due to physical damage, contact an authorized dealer for repair or exchange.

nMake sure there is proper air circulation around the unit. This DVR system uses a hard drive for video storage which generates heat during operation. Do not block air holes located on the bottom, top, sides and back of the DVR as they are designed to keep the system cool while running. Install or place this product in an area where there is ample air circulation.

nProvide proper ventilation. This DVR has a built-in fan that properly ventilates the system. Do not cover or impede this fan.
