xTone: When you press any key, phone generates sound, which consist of two tones. Parameters 1Tone and 2Tone change then. First tone is short, second is emitted all time, when you press key. When you press C, NaviKey, Up or Down keys, change parameter 1Tone only (value 0E10 - 3600 decimal) - sound consist of one tone only. And now the most important thing: you will divide displayed in these parameters values by 4, you will have frequencies in Hz connected with pressing adequate keys in DTMF (Dual Tone Multi Frequency) system. I think, you use DTMF very often - it's used in tone system in all modern phones during calling number. Adequate values are in table (decimal) - parameter 1Tone is connected with vertical values, 2Tone with horizontal:

	1209 Hz	1336 Hz	1477 Hz
697 Hz	1	2	3
770 Hz	4	5	6
852 Hz	7	8	9
941 Hz	#	0	*

Conf: API_CONFIG: connected with sound setting from Test 71 and 72: you will see here number (hexadecimal), which was displayed there below AUDIO ENHANCEMENT (in last selected menu). Here are some examples:

normally (for example during standby)	dialing a number	call
5148 (cracks) - 20808 decimal	5149	5140
851A - 34074 decimal	851B	8512
C6A4 (cracks) - 50852 decimal	C6AD	C6A4
DB34 (cracks) - 56116 decimal	DB3D	DB34
DF29 (after enabling phone) - 57129 decimal	DF29	DF20
F436 - 62518 decimal	F43F	F436
F437 - 62519 decimal	F43F	F436

HFVol: API_HF_VOL: volume during call - you will count it from the "110 - HFVol" formula (subtract value of this parameter from 110). It's displayed too (during call only) in Test 76. When you connect headset, values here change - volume can be count from "510 - HFVol" formula then (for car kit use "2210 - HFVol"). Type of connected audio accesories can be checked in Test 75 too. Phone remembers volume for each audio accesory separately.
