Battery Replacement
Spot Vital Signs LXi 
If necessary, replace the internal battery after heavy use or the battery no longer charges.
1. Power off the Spot LXi and disconnect the AC power transformer cord.
2. Remove the four screws holding the battery door using a phillips-head screwdriver. 
Remove the battery door to expose the battery.
3. Tip the Spot LXi backward and slide the battery out. Disconnect the one-way 
connector and then attach a new battery to the connector as shown. The one-way 
connector ends only connect one way. Do this as quickly as possibly to prevent loss 
of clock time.

4. Slide the battery into the compartment as far as it will go. Push the connector down 
into the case next to the battery. 
5. Replace the battery door and tighten each of the four screws.
6. Connect the AC power transformer to the Spot LXi and allow the new battery to 
charge for approximately 6 hours. The rechargeable batteries in the Braun 
ThermoScan PRO 4000 thermometer requires an additional 1 hour to charge. You can 
use the Spot LXi during this charging period via the AC power cord.
If Spot LXi displays the E38 error code after power up, set the date (see “Date/Time 
Menu Options” on page 32).

The battery is a non-spillable lead-acid battery and must be recycled or 
disposed of properly according to national or local regulations.
