eMate

Basics Overview - 1

Overview

The eMate 300 is a portable computer that has the Newton
operating system and a tablet similar to a Newton, plus a
keyboard. Opening the lid turns eMate power on, and closing
the lid shuts eMate power off. The lid angle is adjustable to
get the best viewing position. With the eMate pen you can tap
choices, write, or draw on the screen. The keyboard keys are
similar to those found on other computers. A few special
keys found along the top of the keyboard make some
operations easier, such as scrolling, searching, and closing
applications.

It is easy to access upgradeable components through a single
back panel. Upgradeable components are the battery pack,
DRAM/Flash expansion connector, and system ROM
connector. Fragile components are easily replaced, including
the keyboard, display, tablet, and backlight assembly.

Basics Beaming and Faxing - 2

Beaming and Faxing

Infrared wireless transmission allows exchanging
information with another eMate or Newton device, or
connecting to a desktop computer. To do this, the infrared
windows need to point directly at each other and should be

¯

less than one meter apart (closer in bright sunlight).

To send or receive a fax with the eMate, connect the eMate to
a Newton-compatible fax modem or use a fax modem card.
See the Newton website for a list of compatible modems
(http://www.apple.com/emate).

Basics Printing - 3

Printing

The eMate can be connected directly to some Apple printers
with a serial or printer cable plugged into the
communications port on the side of the eMate. Plug the other
end of the serial cable into one of these printers:

• StyleWriter I and II

• Personal LaserWriter LS

• Personal LaserWriter 300

• StyleWriter 1200

• Color StyleWriter 2200

• Color StyleWriter 2400

Note:

StyleWriter 4100/4500/6500 series printers are
supported with the installation of StyleWriter drivers
available on the Apple Software Updates: Other Newton
Updates: StyleWriter Drivers 3.0.

Basics Printing - 4

Any PostScript-based AppleTalk LaserWriter printer can
be connected to the eMate with a LocalTalk connector. Plug a
LocalTalk box into the eMate and connect it to another
LocalTalk box. The second LocalTalk box can be on the
network or plugged directly into the printer. To connect a
printer that has a parallel (Centronics-type) interface, use
the Newton Print Pack.

Basics Battery - 5

Battery

The eMate comes with a built-in Nickel Metal Hydride
(NiMH) battery that needs periodic recharging. The battery
normally lasts 24 hours. Using the optional power adapter
with the eMate automatically recharges the battery while
the eMate is in use.

If the battery doesn’t last as long as it should, these
activities may have shortened battery life:

• Setting the eMate to “Never sleep”

• Using backlighting for long periods

• Setting the eMate to receive beams automatically

• Using the communications port for faxing, mailing, and

printing

Basics Resetting the eMate - 6

Resetting the eMate

If the eMate is working erratically, the simplest solution is
to reset the operating system.

Soft Reset

Note:

A soft reset doesn’t erase any stored information in
the eMate.

With a pointed instrument, press the Reset button on the
bottom of the eMate for two seconds to do a “soft reset.” If
the eMate didn’t reset, press the Reset button again for at
least 15 seconds. If a soft reset doesn’t solve the problem,
you may want to do a hard reset.

Hard Reset

Caution:

memory.

To do a “hard reset,” follow these steps:

appears asking if you want to erase your data completely.

will be erased, tap OK.

Basics Sharing Newton Information - 8

Sharing Newton Information

The eMate uses the Newton 2.1 operating system. This means
the eMate can share information with a Newton that has the
same operating system version. The eMate can also use
5-volt PC cards and storage cards from a Newton device
having the same operating system.

Basics Freezing Software Packages - 9

Freezing Software Packages

Freezing packages is a technique used to isolate corrupt or
incompatible software installed in memory. This process is
similar to disabling extensions on Mac OS based computers.

1 Remove any inserted PC cards or application cards.

Perform a soft reset.

2 Press and hold the Power button on the keyboard as the

unit is powering on.

3 When a message appears asking whether to activate

packages, tap “No.”

4 One-at-a time, reactivate and test for corrupt packages

by tapping their “frozen” icons. (To activate all frozen
packages, perform a soft reset.)

5 Ensure you have a backup file of packages. Trash any

corrupt packages, and restore from the backup file.

Troubleshooting General - 1

General

The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts in the order of most likely solution, try
the first cure first. Verify whether or not the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(Note: If you have replaced a module, reinstall the original module
before you proceed to the next cure.)

If you are not sure what the problem is, or if the Symptom Charts
do not resolve the problem, refer to the Flowchart for the product
family.

For additional assistance, contact Apple Technical Support.

symptom to a replaceable module. Replaceable modules include:

• Logic board (included with Top Case Assembly, 661-1194).

• RAM and ROM expansion cards

• Display (Assembly)

• Keyboard

• Battery
