Sound volume | Toshiba GD-1160, GD-1260, GD-1250, GD-1270, GD-1210

The relation between the signals and sound volume is as follows.

Sound volume	VOLSEL2	VOLSEL1	VOLSEL0

Max. (7)	LOW	LOW	LOW

(6)	LOW	LOW	HIGH

(5)	LOW	HIGH	LOW

(4)	LOW	HIGH	HIGH

(3)	HIGH	LOW	LOW

(2)	HIGH	LOW	HIGH

Min. (1)	HIGH	HIGH	LOW

Silent (0)	HIGH	HIGH	HIGH

The monitoring signal whose volume is controlled by IC9 [IC2] is amplified by the OP amplifier (IC10 [IC1]), then output to the speaker.

Signal Name	Type	Active	Description	Destination

SP-SEL	O	H	Line/Tone Selection Signal	IC3

MON	O	H	Ring/Tone Selection Signal	IC3

VOLSEL0-2	O	H	Speaker Volume Control Signals 0-2	IC9 [IC2]

*Values in [ ] are for GD-1250/1270 in case that the descriptions vary between GD-1210 and GD- 1250/1270.
