The HOLUX M-241 wireless GPS logger provides real time coordinate

logging and easy-to-use trip guiding service. The M-241 can record up to

130,000 positions, each position including longitude, latitude, time, and altitude.

The log file can be transfered for analysis via USB connection. You can

combine these positions with your Digital camera photos to share the track

histories and photo locations to mapping application software such as Google

Earth.

Position information, moving speed, free logging volume and the date &

time can be shown on the LCD display directly at any time. The M-241

supports distance and time logging modes, kilometer and mile distance units,

and 5 languages (English, Traditional Chinese, Simplified Chinese, German,

and French).

GPS coordinate of the picture in the camera, because the integration of

the two parties is performed under the comparison of the time, it is

recommended for the user to adjust the clock time in the camera to

match the GPS time in the M-241.

2. M-241 does not have the water-proof feature; please pay attention to

the moisture while using it in a rainy day.

3. Before turning off, please press “stop” button to prevent log data

(Fig. 3)

、、

In the “setup” panel you can see “Hot Start” “Warm Start” “Cold

Start”, which allow you to re-acquisition the Ephemeris and

Almanac. Basically, the satellites are always moving in the sky, if

Ephemeris and Almanac data in the GPS Logger can’t meet real

satellites status or if the GPS Logger has been powered off for over

0.5 hours but you are no longer in the previous position, then it will

take more time for the GPS Logger to obtain a GPS position fix. We

suggest that you click “Cold Start” or “Warm start” to re-acquisition.

Or you can remove the battery for 120 seconds and reinsert it; this

operation is the same as “Cold Start”.
