Helpful DVR Tips 

 

Press ESC to stop all recordings, playbacks, and to back out of menus. Pausing a 
recording and powering off will erase the unfinished recording.  

 

A MAXIMUM VIDEO LENGTH OF 1.5 HOURS IS RECOMMENDED. 

 

Turn the keyboard power off at the end of your use of the system to preserve longer 
battery life. 

 

After 3 minutes of not using the keyboard, the keyboard goes into Sleep Mode and all 
LED indicators will go out.  Keys will not work until it wakes up which takes a few 
seconds.   After it wakes up, the Green Power LED will light and the keys will work again. 

 

If the unit is not operating properly, restoring the setup settings back to Laval 
Underground Surveys factory settings may fix it.  

See “Reset System Parameters” in the 

System Information section.

 

 

Monitor available free memory for both the internal and external storage in the System 
Information screen.  If more space is need on the internal storage you can move files to 
the external storage by copying and then deleting them. 

 

Stop the movement of the camera (reeling up/down or rotating) when using the 
snapshot function for clearer pictures. 

 

Text overlays must be setup and typed in prior to the recording. 

 

IMPORTANT

: When renaming video files, do not change or delete the file extension, the 

“.mp4” or ”.ts” part of the

 name, as this may make the file in-accessible to the system.  

All video files must have the “.mp4” or “.ts” at the end of their file name.  Likewise, the 
“.jpg” at the end of snapshots file names must be treated the same.

 

 

Always keep the keyboard and its USB receiver paired together with one system, refer 
to the serial codes on them in the event that they are mixed with another set.  

 

Larger storage devices such as external hard drives will most likely need formatting to 
FAT32 to work with the DVR. Keep this in mind and test recording before going into the 
field.  

 

Video files recorded as .ts can be converted if they are not compatible with a video 
player, using a video converter. Converted files may not play back on the DVR.
