Battery and AC Power
The PSA1301/2701T can operate using its internal rechargeable batteries, or from AC line using the
adaptor provided by TTi.
17.1. Battery Operation
The Palm T
|
X and the PSA1301/2701 incorporate their own rechargeable batteries. The AC adaptor/
charger provided by TTi recharges both batteries simultaneously. Charge control circuitry ensures that
the batteries will not be over charged.
The PSAnalyzer application provides battery condition indicators for both batteries, the left hand
one is for the PSA1301/2701 (providing only a low battery warning), while the right hand one is
for the Palm T
|
X and incorporates a multi-stage 'fuel gauge' type battery indication.
In normal operation within the PSA1301/2701T, the Palm T|X battery will discharge more quickly than
the PSA1301/2701 battery. The PSA1301/2701 battery also has a shorter recharge time.
However, should the PSA1301/2701 battery become fully discharged, communications between it and
the Palm T|X will stop and the red “WAIT” symbol will become permanently on, and the left hand battery
symbol will indicate “empty”.
Battery life depends upon screen brightness, but should be between three and five hours of continuous
operation from a charge. Recharge time is typically less than four hours.
To conserve the battery the PSAnalyzer application can be put into sleep mode when not in use by
pressing and holding the Home/Back key. Also auto-sleep mode can be selected whereby the unit turns
off automatically after a defined period from the last key press. All data is retained when off.

|
X battery condition
The precise condition of the T
|
X battery can be checked from within
PSAnalyzer by accessing the Task Bar.
To display the task bar, press the Help key.
The task bar is displayed below the help screen text.
To check the battery condition select the “System Info” icon
from the Task Bar. Press the Home key to exit.
17.2. AC Power Operation
The AC adaptor/charger provided by TTi can be used as the permanent power source for the
PSA1301/2701T. If the batteries require re-charging, this will be done automatically and charging
terminated at the appropriate point.
Use only the AC power adaptor provided by TTi. Use of any other power source could cause
damage and will void the warranty.
When connected to the external power source, the right hand battery indicator will show a
lightning symbol.
Auto-sleep switch-off is disabled when external power is connected.
An LED next to the DC power input will illuminate while the PSA1301/2701 batteries are charging.
