REMOTE UNIT CONFIGURATION & OPERATION

8.Fine-tune the LF equalization to remove ‘black video smearing’ - black smears to the right of large objects such as window title bars (see Figure 11).

LF Equalization Commands	Key Sequence

Increase LF Equalization (Coarse)	<L> + <Up Arrow>
Decrease LF Equalization (Coarse)	<L> + <Down Arrow>

Increase LF Equalization (Fine)	<L> + <Right Arrow>
Decrease LF Equalization (Fine)	<L> + <Left Arrow>

9.Fine-tune the HF equalization to sharpen the video image. Increase HF Equalization until a white edge to the right of small characters just starts to appear (see Figure 11).

HF Equalization Commands	Key Sequence

Increase HF Equalization (Coarse)	<H> + <Up Arrow>
Decrease HF Equalization (Coarse)	<H> + <Down Arrow>

Increase HF Equalization (Fine)	<H> + <Right Arrow>
Decrease HF Equalization (Fine)	<H> + <Left Arrow>

On certain monitors, you may obtain a sharper image by overcompensating HF EQ and then decreasing LF EQ to remove any bright streaks.

10.If you are using one or more flat panel monitors in the Remote consoles, carry out auto- adjustment again.

11.Save the settings by pressing the <Esc> key. Alternatively, to discard any changes and revert to the settings stored in the EEPROM, press <Left Control> + <Esc>. The Remote unit automatically exits Command Mode after 30 sec of inactivity and saves all settings, including any changes.
