Setup

Using the Main Power Cut-Off Switch

The Main Power Cut-Off switch is only used to prevent battery drain when iSCAN is not used for long periods of time. Do not use the Main Power Cut-Off switch on a routine basis.

Always press and hold to turn off iSCAN before switching the Main Power Cut-Off switch to OFF and before removing the batteries. Failure to turn off iSCAN using may result in data loss or corrupted memory on the SD card.

wWarning: The Main Power Cut-Offswitch will not protect your iSCAN from damage due to battery leakage when iSCAN is stored for long periods of time. Always remove the batteries from iSCAN when placing it into long-term storage.

Connecting Earphones or Headphones

For private listening, you can plug 1/8 inch (3.5 mm) mini-plug

earphones or headphones (not supplied) in the HEADPHONE jack

on top of iSCAN. This automatically disconnects the internal speaker.

Connecting an External Speaker

In a noisy area, an amplified speaker (not included, available at your local RadioShack or RadioShack.com) might provide more

comfortable listening. Plug the speaker cable’s 1/8 inch (3.5 mm) mini- plug into iSCAN’s HEADPHONE jack.

Listening Safety

Do not wear headphones, earphones, or earbuds while operating a motor vehicle or riding a bicycle. This can create a traffic hazard and could be illegal in some areas. To protect your hearing, follow these guidelines:

•Do not listen at high volume levels. Extended high-volume listening can lead to permanent hearing loss.

•Set the volume to the lowest setting. Then turn on your iSCAN and adjust the volume to a comfortable level.

•Avoid increasing the volume. Your ears will adapt to the volume level, so a level that does not cause discomfort could still damage your hearing.
