Turn your device into an advanced multispectral gadget that includes all sensors you need: GPS, digital compass, gyroscope, accelerometer, camera.
Reach unbelievable precision with the gyrocompass that is similar to air or marine navigation. Forget about any compass interferences. Get a live compass working on devices with no compass sensor.
Find and track your location. Monitor your coordinates in geo and military formats. Check altitude, current and maximum speed, and course. Use imperial, metric, nautical, and military units.
Find directions with the Mil-Spec compass operating in 3D space at any orientation. Monitor direction hints about lots of targets, updated in real time on the azimuth circle.
Measure distances to objects with a rangefinder reticle as in famous sniper scopes in real time.
Observe both your target’s and your own position on maps rotated automatically according to the current azimuth. Use street, satellite, or hybrid maps.
Track the position of any location, bearing, or star along with the Sun and the Moon in real time. Look at the objects through the planet Earth. Some objects are shown with the help of augmented reality. Get information about object distances, azimuths, and elevations.
Visually estimate the heights of buildings, mountains and other objects. Calculate distances from dimensions or vice versa. Get a visual picture of angles and distances measurements.
Tag locations and bearings.
This video shows how you can save your custom places and waypoints, see them on maps or augmented reality displays, and navigate precisely to them later using the gyrocompass mode and navigating by the sun for higher precision.
This video shows how you can share your current or saved location with your friends so that they could easily find the way to it, no matter what device or software they are using.
This overview video shows what you will see when you first open and start using Spyglass. It covers the app's main features, modes, and customization options. how to reset accu chek guide meter
This video shows how you can use the Rangefinder to measure distance to your target. Just like a reticle in a sniper rifle, the Rangefinder in Spyglass is based on the height of an average human (1.7m/5.6ft).
This video shows how you can solve the hazardous accuracy issues, typical of most digital compasses, and get the highest precision possible on your device. The most common and effective method for addressing
This video shows how using the Sextant tool you can measure the size of a building/object if you know the distance to it. Or vice versa – how you can measure the distance if you know the size.
This video explains how to improve accuracy of the compass on iPhone or iPad using maps and the gyrocompass mode. To perform this, press and hold the triangular
This video shows how you can document significant locations, trail hazards, violations, or incidents by grabbing pictures with myriads of positional data overlaid.
This video shows how you can use Spyglass as a backup speedometer for your vehicle, get clear compass directions on back road and cross country road trips, trace your position on the map, and control your vertical speed.
That's how your iPad screen looks when you use night mode maps in Spyglass and Commander Compass apps.
The most common and effective method for addressing a frozen screen or a non-responsive meter is a via a power-cycle. Unlike a computer, the Accu-Chek Guide does not have a "restart" option in its menu. However, simply turning the device off and on again can clear temporary electronic glitches. To perform this, press and hold the triangular "Power/OK" button for approximately two seconds to turn the meter off. Wait for a full ten seconds, then press the same button again to turn it on. This action forces the meter’s internal processor to reboot and reload the operating system, often resolving minor software lags or unresponsive buttons without deleting any stored data. This should always be the first step before attempting any other reset procedure.
If the meter remains frozen or fails to turn on after a soft reset, the next course of action is a . The Accu-Chek Guide operates on a single CR2032 lithium coin-cell battery. To perform this, slide the battery compartment cover located on the back of the meter in the direction of the arrow to open it. Gently remove the battery using a non-metallic tool (like a toothpick) to avoid damaging the contacts. Leave the battery out for at least one full minute. This allows all residual electrical charge to dissipate from the meter’s internal capacitors, ensuring a complete power-down. After one minute, reinsert the battery with the positive (+) side facing up (visible when looking at the meter’s back), and close the cover. Upon powering on, the meter will prompt you to re-enter the correct time and date, as the internal clock may have reset. Crucially, this procedure will not erase your stored blood glucose results . The readings are saved in a non-volatile memory chip, which retains data even when power is completely disconnected.
It is equally important to note what is regarding a reset. You cannot use any sequence of button presses or battery removals to erase the meter’s result history. This is an intentional safety and compliance feature, as the logbook of readings is a medical record. If you need to clear the memory—for example, before giving the meter to another person—you must manually delete each result individually through the "My Data" or "Results" menu, which is time-consuming. Alternatively, consult Accu-Chek customer support, as they may have proprietary service tools for a true factory reset. Also, if the meter displays persistent error codes like "E-1" (temperature out of range), "E-3" (damaged test strip), or "E-9" (meter malfunction), these often indicate a physical or environmental problem that a reset cannot fix. In such cases, referring to the user manual’s error code section or contacting Roche Diabetes Care is the correct path.
