CARE OF THE REMOTE CONTROL
The trackball remote control requires no maintenance, other than battery
replacement when required.  To change the batteries, open the battery
holder on the rear of the handset.  Remove the old batteries and dispose of
carefully.  Insert four new batteries of the type described in the Technical
Data
 section, observing the polarity instructions inside the battery holder,
and close the clip-shut door. Test that the remote control functions
correctly by pressing OSD, which should bring up the OSD.
