Water and dust resistant. Status Indicators Bright LED lights indicate status of device and monitoring. The Trek Tab User Guide Status button, LED Display The Trek Tab LED display utilizes indicator lights in green or red in varying patterns to indicate status. The center LED indicates the recording status. A flashing green LED after a single short button press indicates that the Trek Tab is actively recording. The left [✔] LED indicates with a flashing green LED after a single short button press that the Trek Tab has not experienced conditions that exceed any of the threshold alarm settings. If the button is pressed while the TrekTab is actively recording, the [✔] LED will flash in sequence after the center LED flashing green. The right [✖] LED indicates with a flashing red LED after a single short button press when the Trek Tab has experienced at least one instance of conditions exceeding at least one of the threshold alarm settings. If the button is pressed while the Trek Tab is actively recording, the right [✖] LED will flash in sequence after the center LED flashing green. Shipments To activate the Trek Tab device to track a shipment, press and hold the ‘Push’ button for 3-seconds until the center LED flashes green. Depending on your shipping profile settings, there may be a delay after the unit is activated until it begins recording. 4 Data Transfer In order to access the data recorded on the Trek Tab, it will need to be offloaded by a ​Gateway or the ​Parsyl Mobile App​. To offload data with the app, start by ​logging in​ or selecting ​Transfer Data​. To view the Trek Tab data and analyze findings, log into the ​Parsyl Web Application​ and select the appropriate Shipment from the list within your Company to view the details. 5 The Trek Tab Configuration Settings Excursions An excursion is defined as any time spent outside of “expected ranges” when monitoring your products. Excursion thresholds are defined by your specific needs and set by creating upper and lower limits of temperature. Options for excursions Within our excursion settings, you have two options for tracking the excursions recorded by our Treks: ●Cumulative​ excursions will sum all of the time your Trek Tab records values outside the predetermined range, even if those values temporarily enter back into normal range during the Trek Tab’s journey. Optionally, the Trek Tab can be reset once the alarm has been breached or the device has been turned off. ●Continuous ​excursions occur only when the readings from your Trek are outside the predetermined range, continuously, for a specified amount of time. The timer becomes reset upon detecting that readings have returned to “normal” or “expected” ranges. Alerts The Trek Tab can be configured to display and record varying alert “levels” given certain values and threshold conditions. There are three (optional) severity levels that can be customized to your preferred workflow and procedure requirements: ●Info:​ normal, or expected recordings for data points logged by the Trek Tab. ●Warning:​ “concerning” recordings for data points logged by the Trek Tab. ●Alarm:​ “high-level of concern” recordings for data points logged by the Trek Tab. Note:​ Only alarm and normal conditions are indicated by the LEDs of the TrekTab. Warning conditions are accessible by means of mobile and web interfaces. Customizations Within each alert type, the behavior requested when each severity threshold is met can be customized to your desire. Settings that are customizable for displaying alarms on the Trek Tab include: ●Alarm threshold settings ●Logging start delay Please note that no action is required from the user to ensure uninterrupted use of the device during electromagnetic disturbance. 6 The Android App User Guide Getting Started Shipments Settings 7 The Android App User Guide Getting Started Before you begin, you must have a Parsyl account with appropriate permissions to access the Android App experience for your company’s Parsyl account. Download the Parsyl Android App from the Google Play store, ​here​. Once the download is complete, open the Parsyl App from your Android phone. Log in by entering your email address or phone number and entering the login code we send you. 8 Shipments The Shipments section of the Android app is reserved for the monitoring and analyzing of shipment data recorded by the Trek Tab during its journey. Trek Details Screen Upon scanning the QR code of a Trek Tab, from the Shipments section within the Mobile App, you will be taken to the Trek Details screen. This screen provides an example of the details of the shipment including at least one time-temperature limit violation for each alarm type including the first time-temperature-violation of high and low temperature alarms. 9 The ​Trek Details​ screen highlights the current reading for the given Trek Tab, other details about the Trek Tab including its Product Type, Mode and total monitoring time for that shipment. At the conclusion of a shipment, tap​ Transfer Data​ to transfer the data collected from the Trek Tab device to the Parsyl Web Application for further analysis.

Address: 2825 Larimer Street, Denver CO 80205 USA FCC ID: 2AQ8LTREKC1 1. Product information EUT is a Temperature Data logger, 2.4GHz Bluetooth technology was used for communicating. 2. Limit and Guidelines on Exposure to Electromagnetic Fields According to§15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 Mobile Portable RF Exposure v06, no SAR required if power is lower than the flowing threshold: The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation25 • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. 3. Calculation method [(max. power of` channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 Maximum output power: -0.31dBm = 0.93mW Distance = 5 mm f = 2.402 GHz [0.93/5] * SQRT(2.402) = 0.29 0.29 ≤ 3.0 Therefore, excluded from SAR testing.
