TC73/TC78 Product Reference Guide

Replacing a Battery Using True Hot Swap

This section describes how to replace the battery in premium TC73 and TC78 devices.

Do not put any labels, asset tags, engravings, stickers, or other objects in the battery well. Doing so may compromise the intended performance of the device or accessories. Performance levels such as sealing (Ingress Protection (IP)), impact performance (drop and tumble), functionality, or temperature resistance could be affected.

Do not add or remove a microSD card during battery replacement.

True Hot Swap applies to premium devices only.

If a hand strap is attached, remove the hand strap.

Press the two battery latches down.

Do not attempt to insert fingers under the latches when pulling on the battery. Damage to the latches may occur.

While pressing the latches down, press the two latches in toward the center of the device. The latches must be pressed in completely to release the battery.

Lift the battery from the device.

A 30 second countdown timer displays at the top of the screen. The backup supercapacitor takes over immediately, and the device remains powered with the display dimmed.

If the battery is not replaced after 30 seconds (max.), the device display turns off, and the device enters into memory persistence state for an additional 60 seconds (max.).

Insert the replacement battery, bottom first, into the battery compartment in the back of the device.

Press the battery down until it snaps into place. If the device display turned off, it should automatically turn on.

If the device does not automatically turn on, press and hold the power button for 6 seconds to reboot the device.

Replace the hand strap, if required.
