Operating conditions
Optional freezer units can be
operated at temperatures
between –30 and 140 degrees F
(–34 to 60 degrees C).
The PTC-870IM is designed for use in harsh
environments. Units with a transmissive LCD screen
can be operated at temperatures between 32 and 140
degrees F (0 to 60 degrees C); non-freezer units
with an EL panel display screen can be operated at
temperatures between –22 and 140 degrees F (–30
to 60 degrees C).
Handling the PTC
The following information will help to ensure you
receive reliable and trouble-free service from your
PTC-870IM.
•
Do not open the PTC-870IM’s case. Only a trained
technician can service the parts inside the PTC.
•
Ensure that the PTC-870IM is off before connecting
or removing any accessories.
•
If your PTC has an internal radio, do not operate it
without the antenna installed.
•
Ensure that all accessories are connected correctly.
•
Use only Telxon-approved accessories. Do not
attempt to connect any electrical device that is not
part of your PTC-870IM system to the PTC.
•
If you store non-freezer versions of the PTC in
below-freezing temperatures for more than 1 hour,
you can improve the screen’s performance by
waiting until the unit warms up before using it.
