How-to install a GPS module on a DVL-75 with 300m enclosure

Please Read: Reducing electrostatic discharges.

• Limit your movement. Movement can cause static electricity to build up around you.

• Wear an electrostatic-discharge wrist strap, if available.

• Handle the device carefully, holding it by its edges or its frame.

• Do not touch solder joints, pins, or bare circuitry.

• Please do not leave the device where others can handle and damage it.

• While the device is still in its static-protective package, touch it to an unpainted metal part of the chassis or rack for at least 2 seconds. Touching the chassis drains static electricity from the package and from your body.

• Remove the device from its package and install it immediately without setting down the device. If it is necessary to set down the device, put it back into its static-protective package.

• Take extra care when you handle devices during times of cold weather. Indoor heating reduces ambient humidity and increases the conditions that cause static electricity to accumulate.
