Chapter 3: Operating Information
8570 Vehicle-Mount Computer: Freezer Version
If either the Lucent/Agere 802.11b or the Cisco Air350 802.11b PC card radio*
have not been installed, then both Type II slots are available. When no radio is
installed, the PC card slots are covered with a flat lid, rather than a dome cover.
However, one PC card slot is usually reserved for the radio, leaving the other slot
ready for peripheral cards such as: ATA Flash cards, GPS cards, Nokia Cell phone
cards, etc. A communication card can also be installed for system back up, upgrade,
installation of software drivers, or for interfacing with another computer. For
installation of software drivers, see “Installing Software” on page 39.

3.6 8570 Vehicle-Mount Computer: Freezer Version
The 8570 Vehicle-Mount Computer Freezer/Extreme Temperature version is for use
in temperatures ranging from -35˚C to 60˚C (-31˚F to 140˚F). Although the 8570
Freezer computer can be stored at -30˚C and operated at -35˚C, a cold start below
-20˚C (- 4°F) is not recommended due to radio limitations.
The 8570 Freezer computer is water-sealed to withstand rain in outdoor
environments and condensation in freezer environments, when contact lubricant and
natural grease are properly applied as described below.
Regular maintenance precautionary steps should be taken, such as periodically
inspecting and replacing the contact lubricant (PN 95146) and the natural grease
cable sealant (PN 98083). Check with your Psion Teklogix Service Centre
for details.

strictly followed.
• To help maintain an adequate internal temperature to ensure optimal opera-
tion, the computer should be switched on prior to entry into a freezer envi-
ronment and should be left on at all times while in a freezer environment.
• When not in use, the 8570 can be stored at -30˚C, but ideally should be
stored in temperatures above 0˚C (32˚F).
