Teklogix 7035, 8255 & 8260 Terminals User Manual
• Hand-held LCD terminals used in freezers may require some contrast
adjustment if the display darkens due to a rapid drop in temperature.
• When moving between freezer and warm, humid environments, window
condensation or icing on the outside of the display and scanner window is a
normal occurrence. Wiping the condensation from these windows may
help, but the operator may need to wait until the condensation stops forming
before use.
• To reduce condensation and frost on terminal displays, use an anti-fogging
agent once a week or as required.
• Contact lubricant and connector caps must be used on all external connec-
tors to maintain a moisture barrier and prevent corrosion during freezer and
outdoor use. For 7035 terminals, the contact lubricant – PN 93523 (Dow
Corning #111) must be used. On all versions of 8255/8260 vehicle-mount
terminals, the contact lubricant – PN 95146 (Nyogel) must be used. Further,
the appropriate contact lubricant should be replaced at least monthly in
applications requiring daily or frequent removal of cables. Refer to the table
below for connector cap part numbers.
2.12.3.2 For Hand-Held Terminals Only
• Do not charge batteries in a freezer environment.
• If a hand-held terminal is left in a freezer environment for extended periods
of time with the power off, display response time and contrast are severely
affected. After turning the terminal on, the operator should allow a 15
minute warm-up period outside the freezer before use.
• Battery capacity is reduced as the operating temperature cools based on the
application and the type of radio used. The table below generally outlines
battery capacity based on the operating temperature.
