the volume by a quarter turn. Observe that each digit lights up followed by a scrolling
display of "radel". The display finally shows 00.0. This confirms that the instrument is
ready for operation.
2.4 Select any taal by pressing the number of the group corresponding to the taal. Each
group contains ten leheras in different raags set to the same taal. To select another
lehera of the same taal, press ALT key which would select the next tune. By pressing a

pitch will continue to change till the highest or lowest pitch is reached. Beyond this the
corresponding key would have no effect. FINE TUNING of the pitch is possible by
pressing ALT key before pressing the 'up' arrow and 'down' arrow keys. The fine tuning
is achieved in small steps. When a pitch is selected,
the display changes temporarily to pitch mode. A number following the pitch alphabet
indicates the fine tuned pitch. (eg., D.2 is 2 steps fine tuned above D Sharp and G.-3 is 3
steps fine tuned below G).
2.7 Press SLOW or FAST key to decrease or increase the tempo in small steps. The
display changes to the Tempo mode temporarily and indicates the current tempo in
MATRAS PER MINUTE.

already selected. Pressing START key would start the same lehera again. To select any
particular tune, select the taal number, ALT key, the tune number in that taal group and
the START key in that sequence. (Refer Lehera table for details).
2.10 Select group number 21.0 to obtain a steady pitch for tuning the tabla. (Set the
