Cradle Self Test

On power up, the cradles perform a self-test which checks the RAM and ROM. The
Communications LED flashes during the self-test. The Communications LED on the cradle
reveals the status as follows:
Communications LED Condition
Power up/Self-Test (7 flashes -> off)
LED flashing (8 flashes/second)
LED flashing slowly (4 flashes/second)
If the cradle fails self-test (RAM or ROM failure), power the cradle down and back up. If the
self-test fails again, call the Symbol Support Center for assistance.

Batteries

Primary power for the PDT 7200 is provided by a Lithium-Ion battery. The batteries operate
for 8 hours in typical operating environments, although battery life between charges varies
drastically depending on conditions, equipment options, and power demands.
If the battery is fully discharged and untouched for approximately one week, re-initialize the
battery. Refer to Re-initializing the Battery Pack
