QuickGuide to theGPS Receiver GP-E21 2 3ACQUIRING A SIGNALOnce the receiver is on, check that the red light is blinking.• Fast blink indicates signal not yet acquired• Slow blink indicates signal acquiredIt normally takes 30–60 seconds for the GP-E2 toacquire a signal. Once it has done so it will shift topower-saving mode, at which point the lightwill blink every 3 to 6 seconds. The GPS will func-tion as normal.Note: It may take longer to acquire a signal andreception is likely to be poor under the followingconditions:• Indoors, underground, or near tall buildings• In tunnels, valleys, or forests• Near high-voltage lines• When the receiver is inside a bag or suitcaseThis is true of all GPS devices. Try to work outdoors,with the receiver exposed, and with an unobstructedview of the sky whenever possible.GPS DEVICE SETTINGS MENUFor cameras with GPS device settings menu: In ad-dition to the GP-E2 itself, you can see a status indi-cator on your camera’s LCD whenever the receiveris on. (The EOS-1D X displays this on smaller rearLCD panel.)• Blinking [GPS] = signal not yet acquired• Constant [GPS] = signal acquiredOVERVIEWThe GPS Receiver GP-E2 can record location infor-mation such as latitude, longitude, elevation,direction, and coordinated universal time (UTC) inthe EXIF data of your images as you shoot. Thiscan be valuable in a wide variety of photographicapplications, including travel, architecture, land-scape, forensics, and documentary.Geotags (GPS information) can be applied toRAW (.CR2) and JPEG images only. They are vis-ible in Canon as well as third-party image browsers,raw converters, and digital asset managers. Whencombined with Canon’s Map Utility software, theGP-E2 also allows you to log and view the routeyou traveled. This guide will provide instructions forhow to use the GP-E2 to its full capabilities.COMPATIBILITYThe GP-E2 can transfer data directly through the hotshoe, as you shoot, when mounted on the EOS-1DX, EOS 5D Mark III, EOS 6D, EOS M, Rebel 4Ti, orany later model that displays [GPS device settings]in its Set-up menu. When used with the EOS 7D, theGP-E2 can transfer data only through the -TAL> terminal. The following additional restrictionsalso apply to the EOS 7D:• Geotagging will not work while recording mov-ies.• Geotagging will not work with movies whenusing the Map Utility.• Electronic compass information and automa-tic time setting are not available.With all cameras listed above, as well as all otherCanon digital cameras, you can use the GP-E2 withCanon’s Map Utility application to geotag imageslater with a Windows or Macintosh computer.ATTACHING AND REMOVING THE GP-E2You can either mount the GP-E2 to your camera’shot shoe or carry it separately and connect it to thecamera with an accessory connector cable. Carry-ing the GP-E2 separately will free up the hot shoefor use with an external flash or other shoe-mountedaccessory. It will also allow you to use your camera’sbuilt-in flash, if available. In either case, always besure to turn the GP-E2 off before attaching or remov-ing it.SWITCHING THE GP-E2 ONAs soon as you switch the GP-E2 to or, the red light should blink ap-proximately every 5 seconds. If it does not, you needto replace the single AA battery; otherwise:• Single slow blink indicates battery okay• Three fast blinks indicates battery low
