POWER CONTROL RESET... POWERING DOWN...
The power control circuit needs to be reset by powering down; TS100 will turn
itself off in 10 seconds.
BATTERY IS LOW... POWERING DOWN...
The battery is too low to operate; TS100 will turn itself off in 10 seconds. Plug in
the AC adapter to initiate battery charging. You can use the TS100 while the battery is being charged.
EXTERNAL POWER IS LOW... POWERING DOWN...
The voltage from the switching regulator is too low to operate; the TS100 will
turn itself off in 10 seconds. Verify that the AC adapter is functional and plugged
into the TS100 correctly.
DIAGNOSTIC TEST LOOP IS RUNNING
This loop repeatedly performs basic operations to check address and data bus
activity, control–signal timing, and keyboard matrix operation. If this test results
in an error condition, an error message will be displayed.
Error Messages
If there is a power–up error, the TS100 will beep twice, display an error message,
and turn itself off after 5 minutes.
All error messages will be the result of some internal failure, either hardware or
software. If any error message is displayed, write down the error message and
include it when you send the instrument in for service.
