Power Level Adjustment
Upon start-up, the generator defaults to power level 3 (MIN) and 5 (MAX). The minimum (MIN) power level
is user-settable from power levels 1 to 5. To adjust the power level, depress the UP/DOWN arrow button to
the left of the MIN power level display. Set the power level based on surgeon preference and/or
recommendations provided in the instrument’s package insert (for more information, see Power Levels
section in Chapter 2 – General Description).
Audible Activation Tone Adjustment
The generator has three activation tone sets from which to choose (the mid-pitch tone is factory set).
To choose another tone:
1 Switch power off.
2 Switch power on. Then immediately depress and hold both the STANDBY and HAND
ACTIVATION buttons. When the graphic shown in Fig. 11-1 appears on the display, release the
STANDBY and HAND ACTIVATION buttons.
3 While in the Tone Selection mode, the generator will automatically sequence through the available
tone pitches. To select a tone, depress any button on the control panel. The generator will return to
Standby mode. The tone chosen will be saved until it is changed again by accessing the Tone
Selection mode.
4 Adjust tone volume by turning the knob on the lower left corner of the control panel. A tone will
sound to indicate the volume level selected.
Note: For safety reasons, the audible tone may not be disabled. The audible tone volume
for alarms cannot be changed.
