Freezer Pouch - Motorola WT4090 User Manual

3 - 14 WT4070/90 Wearable Terminal User Guide

Freezer Pouch

The freezer pouch allows the user to use the wearable terminal in a freezer environment on the hip or wrist for use
in voice picking applications. An RS309 or RS409 scanner with an extended cable is required when mounting the
freezer pouch on the hip mount, if scanning is also part of the application.
In order to keep the wearable terminal at a safe operating temperature in a meat or ice cream freezer, the freezer
pouch insulates the wearable terminal to keep the heat generated by the wearable terminal within the pouch. The
pouch is not heated. There are no batteries to worry about or electronics within the pouch.
The freezer pouch can be either hip-mounted or wrist-mounted. For hip-mounting, there is a belt loop on its back
for attached a belt (sold separately). For wrist-mounting, customers can buy either a set of standard-length or
longer-length wrist straps and use them with the pouch. The longer-length wrist straps are recommended for
wrist-mounting over coats. The freezer pouch has openings on each side for wearable scanners and headset
adapters.
While the freezer pouch is designed to allow workers to use the wearable terminal in meat and ice cream freezers,
there are some very important limitations to follow:
•
Do not use in environments that are below -30°C (-22°F).
•
Do not allow the wearable terminal (with or without the freezer pouch) to remain in the suspend mode in
environments below -20°C (-4°F) for more than 10 minutes. This prevents the wearable terminal from cooling
down to the ambient freezer temperature. The pouch maintains the wearable terminal at a sufficient
temperature while it is in use, but lengthy periods of inactivity brings the wearable terminal below its
operating temperature.
•
Do not store wearable terminals in the meat or ice cream freezer. As explained above, this would allow the
wearable terminals to chill to the ambient freezer temperature, which is below their operating temperature.
Furthermore, if batteries were left in wearable terminals stored in the freezer, the batteries themselves could
freeze, which could damage them. At the least, they would not function while frozen.
•
Batteries cannot be charged below 0°C (32°F). Motorola cradles and battery chargers have an automatic
shut-off to insure this.
•
If using wearable scanners with the wearable terminal in the meat or ice cream freezer for a shift, remember
that the RS309 freezer configuration is the correct scanner to choose, due to its lower operating temperature
range and its desiccant pack to remove condensation.
Slide the wearable terminal into the freezer pouch.
