Table 2. Reviewing and Setting the Line Frequency

Press the COMM key to review the Line Frequency setting, or press and hold the COMM key for 3 seconds to set the Line Frequency.

Press the up/down arrow keys until LinE (Line Frequency) appears in the

primary display (comm appears in the secondary display).

Press the ENTER key. LinE appears in the secondary display and the current LinE frequency setting is in the primary display.

For Line Frequency set procedures, press the up/down arrow keys to select

50 (Hz) or 60 (Hz) line frequency (current setting appears bright).

Press the ENTER key to exit. (Pressing any other function key will cancel set operations.)
