Charging and Charge Management

Charging your Bad Elf Flex

Charge your Bad Elf Flex fully before first use. Here’s how to properly charge your Bad Elf Flex:

● Using the supplied USB charging cable, insert the mini-USB connector into your Bad Elf

Flex.

● Insert the other end of the charging cable into the supplied AC wall charger or the

supplied vehicle charger.

● Charge your Bad Elf Flex until the LED on the left turns green.

Operation while charging

You can operate your Bad Elf Flex while it is charging. A charge current of 1500 maH or greater

can sustain unlimited operation regardless of the charge state.

Compatible chargers

The standard configuration for the Bad Elf Flex includes an AC charger and a vehicle charger.

Any standard USB compatible charger may be used as an alternative. The Bad Elf Flex can

support quick-charger adapters as well as standard USB charging from a PC or laptop. The

charge rate depends on the USB charger current.

Temperature limitations

Charging only occurs within the valid temperature range defined in the specifications of this

manual. Battery temperatures outside the listed charge temperature range prevent the Bad Elf

Flex from charging to protect the battery.

Note: The battery temperature may differ from the ambient air temperature as internal

temperatures vary during usage.

Low battery

The Bad Elf Flex actively monitors the charge level of the battery. As the battery’s charge

approaches a low point, an icon appears on the screen. Using the Bad Elf Flex beyond this

point can cause it to automatically shut down to avoid over-discharge of the battery. If this

happens, you must charge the battery sufficiently to restore operation. Normal operation can

begin once the Bad Elf Flex detects either sufficient USB charging or a battery charge level

above low threshold.

Battery Safety

Charge and use the rechargeable Lithium-ion battery only in strict accordance with the

instructions. Charging or using the battery in unauthorized equipment can cause an explosion or

fire, and can result in personal injury and/or equipment damage. To prevent injury or damage:

● Do not charge or use the product if it appears to be damaged or leaking.

● Charge the product only with an approved USB power source that can provide at least

1500 maH of charging current at 5VDC.

● Discontinue charging a battery that gives off extreme heat or a burning odor.

● Use the product only for its intended use and according to the instructions found in this

document.

Logging Features

The Bad Elf Flex produces location data valuable for storage

and analysis after field data collection. The logging feature,

accessed from the main menu, allows you to store different

types of GNSS data. You can also transfer data stored on the

Bad Elf Flex and manage the logging projects.

The Bad Elf Flex records all data in the context of a project, a

logical container of different types of GNSS data. You may

use the default project (created when the Flex starts up) or

create a new project at any time during operation. Each

project may contain one or more of the following types of

data.

● Points - instant or timed in .CSV format

● Track logs - points recorded continuously at the

recording rate configured for this Bad Elf Flex in .CSV

format

● Raw data recordings - both the binary data from the

Bad Elf Flex and a RINEX file. The typical use for

either file type is GNSS data post-correction.

● NMEA logs - a standard ASCII format produced by the

GNSS engine. For more information see the NMEA

0183 standard.

● Project metadata - a JSON file containing information

describing the project contents, information identifying

the Bad Elf Flex that made the recordings, and

date/time information for the project data.

For details on the project container and data files contained

therein, refer to the Data Storage Specifications section of

this document.

Log Instant Point

An instant point records a location sample using the current

GPS fix. If the Bad Elf Flex does not have a fix, then it does

not record anything. When the Bad Elf Flex finishes recording

the point, you’ll hear an audible tone. The Bad Elf Flex stores

the resulting logged point in a .CSV file along with other

logged points.

If you have not already created a project to contain the logged

point, the Bad Elf Flex creates a project for you. You can

create a new project using the Start New Project option as

described below or by using the Bad Elf Flex app.

Log Timed Point

The Bad Elf Flex can record a timed point by averaging the GPS fix over a specified time

interval. The default time interval is 30 seconds, but you can adjust it as needed. The Bad Elf

Flex stores the resulting timed point along with any other logged points in a .CSV file within the

current project.

Actions:

● Press enter button to start recording a timed point. You’ll see the time count down as

recording proceeds. You’ll hear an audible tone once it completes.

● If you press enter button while the timer is still counting down, the Bad Elf Flex

cancels the recording and discards any data recorded so far.

Log Raw GCP (Ground Control Point)

The Bad Elf Flex can record a ground control point as raw observation data in binary format to

be converted to RINEX (Receiver Independent Exchange) format. By default, it converts the raw

data to RINEX 3.x. You can use the Bad Elf Flex app to change the target RINEX version to 2.x.

You can also use the Bad Elf Flex app to configure the recording duration and auto-stop

duration. By default, the Bad Elf Flex will automatically stop recording after 15 minutes. You’ll

hear an audible tone when recording stops. If auto-stop is disabled, recording continues until

you manually stop it.

Actions:

● Press enter button to start recording a raw GCP. The raw GCP recording status

screen then appears.

● Press options button to cancel and discard the current recording or to finish and save

the current recording. Select an option and press enter button or press back button

to continue the recording.

A track log records a series of points at one-second intervals. The Bad Elf Flex stores each

track log in its own separate .CSV file within the current project using the same format as point

data.

Actions:

● Press enter button to start recording a tracklog. Once recording starts, you’ll hear an

audible tone. Notice that the menu item changes to “Stop track logging.”

● Press enter button again to stop recording. You’ll hear an audible tone, and the menu

item reverts to “Start track logging.”

Start New Project

The Bad Elf Flex stores all point and log files in the context of a project. The Start new project

option creates a new project with a name based on the current date and time. (You don’t need

to explicitly start a new project before logging points and tracks, since the Bad Elf Flex will start

one for you when you begin logging of any kind.)

If there is already an open project when you choose the Start new project option, the Bad Elf

Flex stops any logging in progress and closes the current project. It then processes any raw

logs in the project into RINEX.

Actions:

● Press the enter button on the Start new project menu item to confirm the creation of a

new project. You’ll hear an audible tone.

companion app for your operating system. This app is used to check the health of your

hardware, perform firmware upgrades, change settings, and stream correction data to your Bad

Elf Flex.

Bad Elf Flex Tokens

Each Bad Elf Flex Token is good for 24 hours. With one Bad Elf Flex Token you can do any of

the following:

● Unlock multi-constellation and multi-frequency for higher accuracy SBAS (30-60cm

accuracy).*

● Use RTK with your local CORS or VRS network for survey-grade accuracy (1cm).*

● Use L-Band satellite corrections for places without SBAS or Internet connectivity

(5-10cm worldwide).

* If your Bad Elf Flex is permanently unlocked these features do not require a Bad Elf Flex

Token.

Use the Bad Elf Flex app to load tokens

● Scan the QR code on the back of the Bad Elf Flex Token card.

● Or, type in the code on the back of the Bad Elf Flex Token card.

● Transfer some or all of your tokens to your Bad Elf Flex.

● When you require higher accuracy, use a token to activate Extreme mode using the app

or the Bad Elf Flex user interface.

Using a Bad Elf Flex Token does not require wireless data connectivity. Bad Elf Flex Tokens

don’t expire, and you can load more tokens onto your Bad Elf Flex using the Bad Elf Flex app.

Using tokens directly on the Bad Elf Flex

● Select the Tokens menu option from the Bad Elf Flex main menu

● If there are any tokens available, press the enter key to enable Extreme Accuracy

● From the Tokens screen, press enter to enable Extreme Accuracy

RF Disclosures

Class B Statement – Notice to Users:

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.

Note: 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 and Part 90. 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 communication.

However, there is no guarantee that interference will not occur in a particular use. 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 the Bad Elf Flex.

● Consult Bad Elf for help.

Changes and modifications not expressly approved by the manufacturer or registrant of this

equipment can void your authority to operate this equipment under Federal Communications

Commission rules.

Human exposure to radio frequency energy

Like any other mobile device, the Bad Elf Flex emits radio frequency energy (RF) during use.

According to the International Commission on Non-Ionizing Radiation Protection (ICNIRP), the

critical effect of RF exposure relevant to human health and safety is heating of exposed tissue.

According to the Federal Communications Commission (FCC), “Some health and safety interest

groups have interpreted certain reports to suggest that wireless device use may be linked to

cancer and other illnesses, posing potentially greater risks for children than adults. While these

assertions have gained increased public attention, currently no scientific evidence establishes a

causal link between wireless device use and cancer or other illnesses.”

However, above a certain level (referred to as the threshold) depending on the duration of

exposure, RF exposure and the accompanying temperature rise can provoke serious health

effects, such as heat stroke and tissue damage (burns). To avoid hazards to health deriving

from high RF exposure, limits are set in relation to the threshold known to show adverse effects,

with an additional reduction factor to take care of scientific uncertainties. These limits are

generally expressed in terms of the specific absorption rate (SAR). SAR is a measure of the rate

of absorption of RF energy in the body. Tests for SAR are conducted with the device transmitting

at its highest power level in all tested frequency bands. SAR-limits were first established in 1996

by the FCC in the USA and they were then adopted elsewhere.

You can find additional information about SAR at the following pages:

http://fcc.gov

http://icnirp.org

http://ec.europa.eu

Bad Elf Flex has been tested and certified to not exceed SAR limits in the U.S., Canada,

European Union, or Australia.
