· ·
Caution: Do not plug the power cord into any other kind of outlet. This will damage the machine and is not covered under the warranty. The machine does not have a power on/off switch, so the power is turned on and off by simply plugging in or unplugging the power cord.
Direction of insertion
NOTE: To transmit a carbon-backed document, insert a white sheet of paper between the carbon back of the document and the document carrier. · Those containing an easily separable writing substance (e.g., tracing paper written on with a soft, heavy lead pencil). NOTES:
· · ·
When using the document carrier, carefully read the instructions written on the back. If the document carrier is dirty, clean it with a soft, moist cloth, and then dry it before using for transmission. Do not place more than one document in the carrier at a time.
2 Connect the handset as shown and place it on the handset rest.
The ends of the handset cord are identical, so they will go into either jack.
[4] Installation
1. Site selection
Take the following points into consideration when selecting a site for this model.
ENVIRONMENT
· · · · ·
The machine must be installed on a level surface. Keep the machine away from air conditioners, heaters, direct sunlight, and dust. Provide easy access to the front, back, and sides of the machine. In particular, keep the area in front of the machine clear, or the original document may jam as it comes out after scanning. The temperature should be between 5° and 35°C. The humidity should be between 30% and 85% (without condensation).
Make sure the handset cord goes into the jack marked with a handset symbol on the side of the machine! Use the handset to make ordinary phone calls, or to transmit and receive faxes manually.
3 Attach the original document support as shown below.
ELECTRICITY
AC 120V, 60Hz, grounded (3-prong) AC outlet is required.
Caution!
· ·
Connection to a power source other than that specified will cause damage to the equipment and is not covered under the warranty. If your area experiences a high incidence of lightning or power surges, we recommend that you install a surge protector for the power and telephone lines. Surge protectors can be purchased at most telephone specialty stores.
If the machine is moved from a cold to a warm place...
Condensation may from on the reading glass if machine is moved from a cold to a warm place, this will prevent proper scanning of documents for transmission. Turn on the power and wait approximately 2 hours before using machine.
