1.4 Turning On
Press Power key to turn on your Microlog dBX. It takes several seconds to load the operational system, and then the instrument will show you the main display as follows.
Your display will show the icons of programs installed. You may have several programs shown depending on what was purchased. At the top right corner, you can see the clock and the battery power gage.
To run a program, move the focus to the program icon with navigation keys, and press OK key to run it. You can also run a program by double tapping the icon with your finger.
1.5 Charging the battery
The Microlog dBX is designed to run continuously for 8 to 10 hours with a pair of fully charged batteries. When you turn on your Microlog dBX, you can see the condition of the battery power gage at the top right corner of the screen.
To charge your Microlog dBX, plug the connector of power supply to the 7-pin connector (TRIG/PWR) of Microlog dBX. The power supply unit accepts 100 ~ 200 V AC power. During the charging process, if you turn on the instrument, you’ll see that the battery power gage scrolling. It is normal that the casing of the instrument gets a little bit warmer during charging.
You can extend the operational hour in the field by replacing the battery with a backup one. Besides, if you plan to use the instrument within 4 hours, you can use only one battery to reduce the weight.
Handle battery packs carefully
This product contains a Li-ion battery. There is a risk of fire and burns if the battery pack is handled improperly. Do not attempt to open or service the battery pack. Do not disassemble, crush, puncture, short external contacts, or circuits, dispose of in fire or water, or expose a battery pack to temperatures higher than 60°C (140°F).

1.7 Regulatory Information
FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/ TV technician for help.
CAUTION:
Any changes or modifications not expressly approved by the grantee of this device could void the user’s authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to radio waves. This device is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission of the U.S. Government.
The exposure standard employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. Tests for SAR are conducted using standard operating positions accepted by the FCC with the EUT transmitting at the specified power level in different channels.
The FCC has granted an Equipment Authorization for this device with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this device is on file with the FCC and can be found under the Display Grant section of www.fcc.gov after searching on FCC ID: 2A8TK-9260NGW
To ensure that RF exposure levels remain at or below the tested levels, use a belt-clip, holster, or similar accessory that maintains a minimum separation distance of 5mm between your body and the device.
