By pressing the "ENT" , "UP" and "DOWN" keys and holding them
pressed while pressing and releasing the reset switch or removing then returning
the power supply. This will put the unit into a test program. The Display will show
"r" and then "r O" to indicate that the ram is OK. then after a short time the
display will show "d P" to indicate that the default values have been entered, then
after a short time all LED digits and segments will be lit to test if all LED'S are
functioning properly.
When all LED'S are lit press the "ENT" key to reset the unit for normal running.
It may take up to 30 seconds for the Remote display to respond to the TD-196 units
data for display.

matically set all values to there default values if the ram loses its power.
