About the CN80G Cold Storage Model Heater
CN80G Cold Storage (CS) models come equipped with touch screen and scan
window heaters to support extended use in freezers as well as transitions into and
out of freezer areas. The heaters can be set to turn On automatically to defrost the
touch screen and scan window based on external temperature changes and timers
or the user can control the heaters by manually turning them On or Off.
• Automatic mode
This is the default mode of operation for the heaters. Automatic mode
maximizes battery life in cold storage environments and provides average
window defrost times. In Automatic mode, cold storage battery life may exceed
6 hours (scanning a barcode every ten seconds). Window defrost times should
be a minute or less with factory default settings implemented.
If your application requires faster defrost times, you can enable the Preemptive
Heating (pre-heat) feature to minimize defrost times with average battery life
in cold storage environments. This feature slightly reduces cold storage battery
life since the heaters enter a low power pre-heat stage before the computer
detects a rise in the ambient temperature.
In Automatic mode with Preemptive Heating enabled, the cold storage battery
life ranges from a maximum of 6 hours to a minimum of 1.5 hours, depending
on the heater
Preemptive delay time set. The window defrost times range from
zero to a maximum of one minute with factory default settings.
• Manual mode
This mode is disabled by default. When enabled, heater activation is controlled
solely by the user. No temperature monitoring and timers are used to control
the heaters. The user must manually turn the heaters On or Off.
Use the Settings app to configure the Heater feature. To learn how, see Heater
Parameters on page 31.
