Teklogix 7035, 8255 & 8260 Terminals User Manual 41
Chapter 2: Assembly And Basic Operation
For Vehicle-Mount Terminals Only
2.12.3.3 For Vehicle-Mount Terminals Only
• 8260 LCD freezer vehicle-mount terminals have a delay programmed into
the software to prevent the display backlight from turning on if the internal
temperature sensor is below 10˚ C. The duration of the delay is between one
and two minutes, depending on the temperature measured by the sensor.
This delay is required to heat up the backlight tube, preventing damage
during cold temperature start up. Although the terminal is operational
during this time, it is extremely difficult to read the display until the back-
light is turned on.
Warning: Do not install a non-heated keyboard in an 8260 freezer
terminal.
Conversely, do not install a heated keyboard in a standard
tempera-
ture 8260 terminal.
Warning: Do not install the terminal in such a way that the power cable is
bent 90˚ at the terminal. Doing so may cause damage to the power
cable and power cable strain relief.
• To prevent condensation when a vehicle-mount freezer terminal is moved
from a freezer to a warmer environment, it is recommended that the termi-
nal power be left on for at least five minutes.
• When not in use, 8260 LCD vehicle-mount freezer terminals should be
stored in temperatures above 0˚ C (32˚ F).
• To prevent keyboard keys from freezing up, the keyboard should be
mounted off the horizontal plane. This allows water to run off the keyboard
and prevents it from pooling on the keypad, freezing and finally physically
jamming the keys. Mounting the keyboard off the horizontal plane also
prevents water from dripping onto the keypad area.
