Telular CDMA SX5T-500C User Manual

If your SX5T has a Power Supply, you may install emergency batteries to power the device in the
event of a power outage. 

Do not install emergency batteries if your SX5T has a BBU. The SX5T

will not automatically switch to battery if AC power fails; you must flip the AC/Battery switch to battery
operation - see Figure 5.

Remove the battery access door screw located on the bottom of the unit - see Figure 4.

Press the battery access door tabs and remove the battery access door.

Install 4 “AA” alkaline batteries (not supplied) - see Figure 4.

Reinstall the battery access door using the screw.

SX5T models with Power Supplies will not automatically switch from AC to battery upon loss of AC
power. The AC/Battery switch must be changed manually - see Figure 5. Battery power will provide
up to 3.5 hours of standby or up to one hour of talk time, depending on the SX5T model.
